Kirsch Kunststofftechnik specialises in many different processes for surface coating of plastics. One of the main areas is production of scratch-resistant and transparent coatings under cleanroom conditions.Kirsch Kunststofftechnik has successfully established itself as a leading supplier in this field...more

Heat-curable coating systems

We apply an extremely wide variety of transparent coatings in our large Class 1000 cleanroom. Components with dimensions of up to 3,000 mm x 2,000 mm can be coated here. The coatings are applied by means of flood coating. This method is used to manufacture components with absolutely perfect surface quality.

The advantage of this process is that flooding produces a flushing effect and rinses off any remaining dust particles. This process allows application of a very thin film. It is used for coating of either sheet products or finish-moulded parts. Kirsch Kunststofftechnik processes all common scratch-resistant coating systems such as PHC587, AS4000 and AS4700. The plastics used are normally PMMA und PC. The coatings provide the plastics with a protective layer in addition to their existing properties. This layer protects the materials against scratching and damaging UV radiation.

The coatings also increase resistance to chemicals. This is advantageous for many applications in the fields of mechanical and automotive engineering in particular.

UV-curable coating systems

UV-curable coatings are processed in a separate cleanroom at Kirsch Kunststofftechnik. We have various installations with different concepts in this room. We operate an automated continuous coating installation for components up to a width of 350 mm. Coating takes place either using the flooding method or in a spray coating installation. After coating application, the components pass through a heat tunnel and then the corresponding UV unit. Thanks to process automation and absolute cleanliness, components of the highest quality can be produced here both quickly and inexpensively.An additional UV unit further extends our production possibilities in this coating field. This installation allows double-sided curing of components with a height of up to 700 mm. An inert gas such as nitrogen can also be introduced additionally here. This process allows further reinforcement of the coating properties. Kirsch Kunststofftechnikcan call upon decades on experience in practical application of this process.
