Coatings for the Printing Industry
Save Money and Increase Productivity

The printing environment presents many challenges that can sap the printer's ability to remain productive and to cut costs. There are mechanical issues with the flow of materials at various stages of completion through conveyor systems and chutes, against sliding plates etc. The environment is full of chemicals that are not only difficult and costly to clean, but sometimes corrosive and harmful to machinery and equipment.


However a vast range of coatings has been developed to deal with these issues. These coatings include polymers, ceramic and metal coatings that provide a choice of properties that can help to reduce costs and increase productivity.

Easy Clean
The increase of water-based technology and the variety of substrates, inks, coatings, and adhesives that form today’s packaging place great demands on press drying and cooling systems. Should press tolerances be exceeded, even momentarily, undried inks and coatings form deposits on roller surfaces, causing print defects and costly cleaning stoppages. The excellent release properties of plasma coatings have proved invaluable for increasing wear resistance minimizing deposits on print contact rollers.

Special Coatings For Metallic Inks
Metallic inks such as gold or silver are easier to clean off a coated surface than a bare metal surface, but might still leave a residue. Often this residue requires the use of solvent to remove it; not much solvent perhaps, but in an environmentally friendly factory the use of even small quantities of solvent will be avoided if possible. Fortunately there are available special coatings that avoid residues from metallic inks for a small price premium that pays for itself in savings of labour, materials and waste disposal.

Improved Colour Print Quality
A colour change is a major source of downtime. The ink dries on the pans, then the pans must be scraped and washed before a different colour ink can be used. This can take hours. The process can be reduced to minutes by coating the ink pans; thereafter, drain the pan of all ink, and simply wipe the residue with a damp rag. Not only is the pan cleaning time reduced, but so also is the surface tension, and this helps the ink to stay dissolved more easily for a more homogeneous colour and a better print product.

Non-Stick
A Swedish label printer achieved “Zero Defects” by having a plasma coating applied to the idler and waste rewind rollers on their label printing machines. Now label stock which has adhesive on the edges can no longer stick to the rollers. The tolerances for applying the ink have become much tighter, and the improved ink registration and printing process have led to a higher label quality. Costly downtime due to labels jamming has been eliminated and the equipment is also more durable thanks to its hard release surface.

Quicker Ink Changes
In a sheet-fed offset press, ink is poured into the ink duct at the top of the inking system and flows from there into the inking system. Every time the ink is changed, the ink duct has to be cleaned. Sheet-fed offset ink is tough to remove. Even very small traces of the old ink cause waste because when the new ink is mixed with the old, the printing quality is affected. By applying the appropriate coating to the duct, less time is needed for ink changes and the risk of cross-contamination is minimised. Employees can change the ink quickly and with little effort, and the reduction in downtime increases productivity.

Hardness and Durability
Laminating rollers require non-stick properties and good traction attuned to the film to ensure safe and reliable web transport. It is also important that the surface structure of the roller does not damage the delicate film, and must also be resistant to wear even when very abrasive substrates are processed. Plasma coating can lend all of these properties.

Its outstanding non-stick properties prevent deposits of sticky substances. There is no residue on the laminating roll, even when it comes into direct contact with the adhesive. Product deposits around the edges can be removed with a damp cloth. The spherical surface structure of the coating ensures that the film material is guided precisely but is not scratched. The high degree of hardness (70 HRc) ensures a long operational lifetime.

High Traction
Because of the fragility of tissue paper, perfect traction is required on both the draw and winding rolls. These pull the tissue from the stock roll and feed it onto the cardboard core to create the final product. These two rolls are very high-wear areas due to the stop/start nature of the process. They also become less effective from the build up of hot melt adhesive within the traction area. Plasma coatings can solve the three requirements of perfect traction, high-wear, and hot melt non-stick.

Reduce Damage to Rollers
Ink and varnish builds up on idler rollers, and normally can be removed only by scratching it off. This leaves grooves on the roller surfaces. A high quality polymer coating can prevent such build-up almost completely. It is easy to clean the roller surfaces from time to time with a rag soaked in solvent, without scratching the surfaces.

Cleaning/Maintenance of Ink Pumps, Cross Contamination
Ink pumps tend to become clogged up with dried ink and the printer cannot strip off the dried ink to carry out maintenance. By coating the pump the ink doesn’t stick to it, which means no clogging up. This means a cost saving to the printer because any maintenance is easy to carry out and can be completed in house. Also, the ink can easily be hosed off with water, which means the pumps can readily be swapped from one colour to another without cross contamination.

Increase Up-Time on Varnishing Equipment
The cleaning of varnishing stations takes a lot of time and labour, and is not a popular task. To minimise this costly downtime one manufacturer opted for a polymer coating. The coating creates a wax-like surface, which prevents the build-up of residue on the surface of the varnish tray. This cuts down greatly on the time and effort needed for cleaning and therefore returns the equipment to production more quickly.

Reduce/Eliminate Cutting/Abrasion Damage, Increase Safety
A plasma coating can increase the hardness of roller surfaces, reducing abrasion damage and facilitating the use of cutter knives and other sharp instruments against the face of the roller. Use of these coatings for the production of plastic film can eliminate the need for costly renovations caused by knife scratches on the rolls. Production runs more smoothly as the occurrence of scratches used to cause the plastic film to twist and curl, resulting in operational interruptions. Prevention of injuries due to abrasions on the rolls has also lead to greater safety for the machine operators.

Increase the Efficiency of Conveyor Systems
An area not often thought about is the equipment used to convey the product around the factory. Polymer coatings are excellent for the conveyor side guides and rails for low friction, and plasma coatings are ideal for the driven conveyor rolls for traction without damaging the conveyed material.

Fluoropolymer Coatings

Fluoropolymer coatings are used in a number of key applications. For example, where low friction or non-stick is required. If corrosion resistance is the objective, then Halar (ECTFE) or PFA are often used. Conductive coating versions are also available.
Fluoropolymer Coatings >>

TempCoat ®

The TempCoat® range is the family name given to the fluoropolymer coatings applied by Impreglon UK. The TempCoat® method creates a high quality polymer surface. These coatings have excellent sliding, non-stick, release and dry lubrication properties and the TempCoat® process ensures that the coating is securely anchored to the base material (substrate).

TempCoat >>

Xylan® Coatings

Click the link below for more information on xylan coatings.
xylan® coatings >>

MagnaCoat ®

MagnaCoat® surfaces are heavy-duty fluoropolymer coatings which are pinhole free. They can also offer good non-stick properties and some have high electrical and impact resistance, even at elevated temperatures. The coatings provide excellent barrier protection to resist aggressive chemicals and other sources of corrosion. The MagnaCoat® range of coatings are probably the best corrosion resistant coatings available.
MagnaCoat >>

 

Low Friction Coatings

Where low friction coatings are needed, PTFE coatings are usually used. Hard wearing low friction coatings can be achieved when combining fluoropolymer coatings with plasma reinforcement (such as stainless steel, Tungsten Carbide or ceramics).

Anti Corrosion Coatings

Special coatings that offer galvanic protection can be used to create a barrier layer. These coatings corrode in preference to the substrate when the coating is damaged. In addition we have corrosion resistant coatings where corrosion is prevented from happening due to the non-porous nature of the protective coating.

Impreglon has a wide range of anti corrosion coatings with varying film thicknesses.
Anti Corrosion Coatings >>

Chemical Resistant Coatings

These coatings, such as Halar, have thicknesses that range from around 200 microns to over 800 microns. Some of these coatings will withstand very aggressive and abrasive environments. Impreglon chemical resistant coatings can be found throughout the chemicals and petrochemicals industries and applied to parts ranging from valves to vessels.
Chemical Resistant Coatings >>


Non Stick Coatings

Special polymers (fluoropolymers, such as PTFE) reduce the surface energy of the substrate surface and prevents many different substances from sticking. The choice of non-stick coating from the hundreds available to Impreglon UK is made based on experience and knowledge on how different fluoropolymers behave in different applications.
Non Stick Coatings >>

Plasma Coatings

The PlasmaCoat® method combines the outstanding hardness and wear resistance of thermally sprayed metal and ceramic coatings with the non-stick and sliding properties of polymers (both fluoropolymers and other polymers).
Plasma coatings can be used in their own right to give hard wearing surfaces.
Plasma Coating >>

 

Polyurethane Coatings

Polyurethane coatings come under the TempCoat® umbrella and are used to give impact resistance and sound deadening. Usually applied at thicknesses from 1mm upwards, the polyurethane coating system is available in a range of colours.
Polyurethane Coatings >>

ECTFE Coating

Halar® ECTFE, a copolymer of ethylene and chlorotrifluoroethylene, is a semi-crystalline melt processable partially fluorinated polymer.

Choosing the best coating system for a particular application comes from many years of experience and a comprehensive knowledge of our industry. We won’t simply offer you the cheapest coating or the one that suits us – we’ll offer you what we believe is the best for the job. So don’t be surprised if we ask you lots of questions as we need to fully understand your problem and requirements. As a key industrial coating solutions company, we take pride in our workmanship.

We have a close working relationship with Whitford, who manufacture fluoropolymer coatings under the Xylan® brand, and with Chemours, who manufacture the Teflon® range of coatings. This ensures we are kept abreast of the latest developments in coating technology.

It is a common misconception that Xylan® or Teflon® is an individual, specific coating. In fact they are brand names which cover a huge range of fluoropolymer coating systems. A fluoropolymer has a Fluorine atom in it – hence the F in PTFE for example. The system may be a single layer, two layer or three or more layers. The coatings themselves are based on different resins, such as PAI (polyamide-imide), PPS (polyphenylene sulphide), epoxy and polyurethane.

In addition to resins and fluoropolymers, the coating systems have additives, pigments and fillers to achieve specific properties: corrosion protection: abrasion resistance: electrical conductivity / resistance; lubricity; aesthetics; non-stick; thickness; colour. The ratios of these various ingredients are varied to achieve different results. All of this is carried out by the coating manufacturers.

But you need not be concerned about choosing the best coating system – that’s our job!

The coatings are applied by us here at our purpose built facility in Tamworth. In some cases we may utilise the coating facilities of our sister companies - for example, if you require very high volumes of fasteners to be coated, we would liaise with one of our European facilities who specialise in this field.
