CYMEL® 385 resin is a methylated high imino melamine resin with a low degree of alkylation. Being supplied in water, it is recommended as a crosslinking agent for hydroxyl-containing emulsion polymers and other aqueous systems containing hydroxyl or amide functionality. It has a high tendency to self-condense and may be used to increase the hardness and resistance properties of thermoplastic waterborne polymers.
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.
