Phenolic and amino crosslinkers are used with epoxy, polyester, acrylic and alkyd resins and provide the desired balance of flexibility, exterior durability, chemical resistance and film toughness. CYCAT® acid catalysts enhance crosslinking for low acid-containing polymers and lower-temperature applications. The new CYMEL® NF formaldehyde-free crosslinkers are ideal for applications where formaldehyde emissions are a concern.
