CYMEL U-216-8 resin is a partially n-butylated urea crosslinking agent supplied in a mixture of n-butanol and xylene. It possesses a lower molecular weight than most other butylated ureas, which contributes to its low bulk viscosity and high degree of hydrocarbon tolerance. CYMEL U-216-8 resin displays excellent compatibility with most hydrophobic resins, such as epoxies, and can contribute to improved leveling and adhesion characteristics. CYMEL U-216-8 resin is recommended as a crosslinking resin in primer coatings, can coatings, and metal deco finishes.
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.
