BYK S 780 is an additive used to prevent surface tackiness in resin systems. It forms an optimal film on the resin surface that prevents the inhibiting effect of atmospheric oxygen, ensuring tack-free surfaces. BYK S 780 additive is particularly suitable for use in vinyl ester resins and can also be used in orthophthalic resins. It prevents surface oxidation issues in resin systems, allowing for improved material performance. BYK S 780 additive provides benefits like reduced surface defects, improved mechanical properties and interlaminar adhesion in resin composites. Resin composites are widely used in the Advanced Materials industry for applications that require high strength, corrosion resistance and durability. BYK S 780 additive helps resin composite manufacturers overcome surface oxidation challenges and provides enhanced material quality for demanding Advanced Materials applications.
