Catalysts / Accelerators / Initiators

Based on 515 products - Last update on the Jun 26, 2025

Catalysts / Accelerators / Initiators appear as clear liquids, powders, or pastes. Key features include customizable reaction rates, improved cure depth, and the ability to enable room-temperature curing. Used in automotive assembly, construction, and industrial maintenance applications where production efficiency is paramount. 

Market trends show the development of more environmentally friendly catalysts with reduced toxicity and lower dosage requirements and dual-cure systems that combine different activation mechanisms to ensure complete curing even in shadow areas or deep sections. Various types exist including peroxide initiators for free radical polymerization, metal-based catalysts for condensation reactions, and photoinitiators that respond to specific light wavelengths.

Cardolite® NX-2026

by Cardolite

Cardolite® NX-2026 is a high purity cardanol, bio-based diluent, resin modifier, and accelerator designed for use in adhesives and sealants. It is based on natural, renewable, non-food raw material feedstock. Exhibits very low viscosity, low volatility, excellent water resistance and corrosion protection originating from its chemical structure, long hydrophobic aliphatic chain and aromatic ring. Cardolite® NX-2026 is suitable to be used as a diluent and an accelerator for epoxy adhesives and an isocyanate blocking agent. In adhesive formulation, Cardolite® NX-2026 can improve workability by reducing viscosity and help to achieve fast cure in solvent free formulations. It is recommended for 2K Epoxy adhesives, pressure sensitive adhesive, hot melt adhesives for fabric lamination, 1K/2K epoxy-PU hybrid adhesive, wood/ paper adhesives and industrial adhesive applications. The recommended use level of the product is <20% of total resin weight.
