Epoxy Novolac Resins for Increased Heat and Chemical Resistance

High-functional EPIKOTE™ and EPON™ Epoxy Novolac (EN) Resins are specifically designed to:

Increase glass transition temperature (Tg)
Improve thermal resistance
Improve mechanical resistance
Improve chemical resistance

Increasing the functionality in epoxy resins allows formulators to achieve higher crosslinking densities and significant performance enhancements. A variety of backbones are available with functionalities between 2.5 and 8. Epoxy novolac resins are broadly utilized as primary epoxy resins or as modifiers in multi-resin systems. High functional epoxy resins are preferred in high performance:

Coatings
Containment systems
Composites
Structural adhesives
Electrical laminating and electronics
