DESMOCAP 14CNB is a linear polymer with ether and urethane groups containing crosslinking and blocked isocyanate groups. It functions as a raw material for use in the flexibilisation of epoxy resins and the formulation of flexible coatings and sealing compounds. DESMOCAP 14CNB provides flexibility and elongation to cured coatings and sealants. It improves the elasticity, durability and crack resistance of cured films. DESMOCAP 14CNB can be used to formulate curable, liquid polyurethane systems. When combined with epoxy resins, DESMOCAP 14CNB takes on the R function of a reactive flexibiliser, improving the flexibility and elongation of the cured coating without compromising on other properties. The product is supplied as a high viscosity liquid and offers benefits of flexibility and durability in coatings and sealant applications.
