KEY FEATURES

Superior surface quality and cosmetic perfection
Up to 30% styrene emission reduction
Wide range of applications and flexibility
High chemical resistance and low scaling

Formulation Types

Technical Advantages

Superior Surface Quality

The DCPD component helps to create a better cosmetic finish on finished parts with less stress and distortion. This feature, which is becoming increasingly popular in open molding, significantly improves the visual quality of the final product.

Low Styrene Emission

The use of DCPD in resin formulations makes it possible to reduce styrene levels by up to 30% and thus reduce styrene emissions for manufacturers. This environmentally friendly feature facilitates compliance with occupational safety and environmental protection standards.
