Product Features

APU 42 is based on new, environmentally friendly technology and offers a great alternative to solvent based sealers.

Due to its chemical construction APU 42 is not resistant to yellowing. Therefore a sealing top layer using APU 46 is necessary. If a photo stable polyurethane is required see APU 41

APU 42 is extremely resistant to water-based solutions, diluted acids and alkalis as well as engine and fuel oil.
