Trimethylolpropane Triacrylate (TMPTA) CAS 15625-89-5 is a trifunctional acrylic monomer used extensively as a reactive diluent and crosslinker in UV/EB-curable coatings, inks, adhesives and composite resins. With three acrylate groups, TMPTA imparts high crosslink density, solvent resistance and mechanical strength to cured networks, delivering rapid cure response and outstanding hardness. It is commonly employed where

n-Butyl Isocyanate CAS 111-36-4 is a simple aliphatic isocyanate used as an intermediate in organic synthesis and specialty chemical manufacture. The reagent is reactive toward nucleophiles such as alcohols and amines to form urethanes and ureas, enabling its use in small-molecule derivatization, polymer modification and the synthesis of tailored intermediates. Because of its reactivity, n-Butyl

4,4′-Methylenebis(phenyl isocyanate) (commonly called MDI) CAS 101-68-8 is a primary diisocyanate used extensively as a reactive intermediate in the production of polyurethanes, prepolymers and specialty isocyanate derivatives. MDI provides rigid aromatic backbone segments that impart mechanical strength, thermal stability and chemical resistance to polyurethane foams, elastomers, coatings and adhesives. It is typically handled under controlled

3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexane carboxylate (ERL-4221) CAS 2386-87-0 is a difunctional cycloaliphatic epoxy monomer widely used in high-performance thermoset formulations. The molecule contains two 3,4-epoxycyclohexyl moieties linked via an ester bridge, delivering low-viscosity, highly reactive epoxy functionality with excellent UV and thermal stability. ERL-4221 is favored for coatings, laminates, adhesives and composite matrices where weathering resistance, low

Trans-3,4-Pyrrolidinediol CAS 9046-10-0 is a small, dihydroxy-functionalized pyrrolidine derivative used primarily as an organic intermediate in pharmaceutical and specialty chemical synthesis. The compound presents two vicinal hydroxyl groups on a pyrrolidine ring, providing useful reactivity for etherification, esterification, protection/deprotection chemistry, and as a chiral building block in the preparation of active pharmaceutical ingredients and fine

Benzyl methacrylate (CAS 2495-37-6) is a methacrylate monomer bearing a benzyl ester substituent. It is a clear, low-viscosity monomer commonly used as a comonomer in acrylic resins, specialty coatings and adhesives to impart hardness, gloss and improved adhesion to substrates. The benzyl moiety increases the refractive index and can modify polymer Tg and mechanical properties
