Conformal Coating

World-class PCBs are coated by WERNER WIRTH

WERNER WIRTH offers firmly secure PCB protection - from components partially coated with thin film to completely sealed parts with protection from the sun, from acids and also visual protection.

We supply precisely mixed coating materials with exactly timed post-submersion curing and subsequent durability in use as required by the  environment in your project.

Premium component protection by WERNER WIRTH:

open or closed, transparent or opaque, suitable for every temperature and individually made to measure.

When it comes to premium component protection by conformal coating, the standards are set by WERNER WIRTH, the only specialist for connection technology and component protection from a single source in the electronics industry. You too can benefit from our experience and our one-stop shop platform: alkyd resins, acrylics, acrylic components and polyurethane, solvent or water based coatings and UV or moisture curing coatings. And if it's not available off the shelf, we'll develop and implement it for you and your project.

Spoilt for choice at WERNER WIRTH: on request, we supply just the material, the ready coated product or the right machinery, from manual system through to bulk production module.
