Curatives for epoxy and isocyanate-reactive systems
Amines and other reactive N-H compounds are widely used as curatives, chain extenders, and crosslinkers for epoxy, isocyanate, and other reactive polymer systems. They present the chemist and formulator with virtually limitless opportunities for customization of reactivity profiles and final polymer properties by varying the number, type, and position of reactive N-H groups.

Dytek® Amine Initiated Polyols
Dytek A + PO
Specialty polyols based on multifunctional amine initiators serve as excellent cross-linking agents and catalysts for use in polyurethane coatings and rigid & flexible foams. With a functionality of four and two tertiary nitrogen atoms, diamine-initiated propylene oxide-based polyols provide multiple cross-linking sites with autocatalytic properties. The unique asymmetry and longer backbone of Dytek® A delivers its well-known benefit of lower viscosity compared to similar polyols based on symmetric diamines.
