SM-660 is a premium versatile epoxy reactive diluent in Kukdo’s SM series, designed for viscosity adjustment and processability optimization of epoxy resin systems. As a glycidyl ether type diluent with butyl glycidyl ether as main component, it features ultra-low viscosity and excellent reactivity, fully participating in curing without volatile residues.
Ultra-low viscosity - Significant viscosity reduction effect, greatly improving resin fluidity
Unlimited system compatibility - Miscible with most epoxy resins without delamination or precipitation risk
Reactive curing participation - Contains active epoxy groups, fully participating in curing without affecting cured product integrity
Enhanced processability - Improves resin wetting and penetration on complex substrates, extending pot life
Cost-effective modification - Achieves significant modification effect with small addition, optimizing formula cost structure
Solvent-free coating formulation - Viscosity adjustment for industrial protective coatings and high-build coatings, improving processability
Epoxy resin casting - Modification of resin systems for electrical insulation castings and large component castings
Epoxy potting materials - Fluidity optimization for electronic component potting compounds and sealants, ensuring uniform filling
Floor coating preparation - Processability improvement of epoxy floor coatings, enhancing penetration into concrete substrates
Structural adhesives - Viscosity adjustment for epoxy structural adhesives and repair adhesives, improving bonding surface wetting
