Coatings for elastomeric products

ParCoat Coatings from Parker Prädifa for smooth and reliable installation of seals

During assembly processes, there is a risk of seals that look near-identical but have different functions being mixed up. 

Another risk is that of seals being damaged during installation due to high assembly forces. 

Typically going undetected initially, both of these potential error sources may lead to premature failure of the entire sealing system with respective consequential errors and costs.

In addition, high-volume manufacturing of elastomer seals supplied as bulk material that is separated in conveyor systems entails the risk of seals sticking together.

The resulting stacking of sealing elements may lead to in-process trouble up to and including line standstill.

Systematic modification of surface properties

With ParCoat coatings the surface properties of elastomeric components can be systematically modified and optimised. They are suitable for all commonly used elastomer grades and clearly reduce assembly forces, among other things. 

For instance, with standard connectors on automotive air conditioning systems, a reduction by 50% and more can be achieved compared to uncoated O-rings or O-rings with other coatings.

Clean separation, depositing and feeding in high-volume production is ensured by choosing a respective ParCoat coating as well.

 Colour coding prevents mix-ups

Various coatings in coloured and transparent versions are available, depending on the application requirements. 

Coloured versions serve to mark products and to avoid mix-ups. In addition, for corporate identity purposes, elastomer seals may be coated in the customer’s corporate colour. 

Especially for small or special production series, for which the development of a respectively coloured material is not economically feasible, ParCoat coatings are an easy and cost-effective way to provide elastomeric components with the desired colour. 

On the other hand, transparent versions are used to coat coloured basic compounds when the basic colour must not be altered.
