Cross-Linking Agents & Accelerators

Descriptions 1.A cross-linking agents A cross-linking agents is a poly isocyanate applied to a 2-component adhesive.Mixing a cross-linking agent with 2-component adhesive results in a cross-linked film with good adhesion, elasticity, and chemical and solvent resistance. The adequate level of hardness may be obtained by controlling the adding amount of cross-linking agents. Item Solid (%) Viscosity(ps/25'c) Solvent NCO % Characteristics & Application H-75 74~76 V~Y ET/AC 12~14 Cross linking agent, general type. Synthetic leather & textile. H-75NY 74~76 A2~B EA 15~16 Cross linking agent, non-yellowing type. Synthetic leather & textile. 2. An accelerator An accelerator acts as a catalyst for the reaction between 2-component PU adhesive and a cross- linking agent. The pot-life(cross-linking time) may be regulated by controlling the adding amount of accelerator applied to the adhesive.
