Reactive diluents are clear, low-viscosity liquids with mild to moderate odors. Key features include effective viscosity reduction, improved substrate wetting, enhanced filler incorporation, and minimal impact on final adhesive properties. They're particularly valuable in epoxy, polyurethane, and acrylate adhesive systems for electronics, composites, and precision bonding applications.
The market increasingly favors low-toxicity and bio-based reactive diluents addressing environmental and workplace safety concerns. Common types include monofunctional varieties offering maximum viscosity reduction, difunctional options providing balanced properties, and multifunctional versions minimizing network disruption.

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.
Cardolite® Ultra LITE 513 by Cardolite is a low viscosity, mono-functional epoxy reactive diluent. The long hydrophobic aliphatic side chain of cardanol gives this product a very low viscosity and provides excellent water resistance, flexibility, and thermal shock resistance. High viscosity solvent or solvent-free formulations can achieve enhanced workability and higher solids without sacrificing other performance properties using this product. Recommended use level for Cardolite® Ultra LITE 513 is 2-20% of total resin weight. It is an excellent alternative to glycidyl ether diluents because of favorable health hazard labeling, hydrophobicity, and mechanical properties. Used in 1K/2K epoxy adhesives including transportations, industrials and electronics sectors.
