High-Quality Resin Epoksi Manufacturer & Supplier

Epoxy acrylates (Resin Epoksi acrylates) are synthesized by ring-opening diglycidyl ethers of bisphenol A with acrylic acid. They possess rigid aromatic backbones with high pendant hydroxyl density, giving phenomenal cure speed, outstanding chemical resistance, high surface hardness, and superior substrate wetting at an economical price point. Polyurethane acrylates incorporate aliphatic or aromatic diisocyanates with flexible polyol blocks, delivering elastomeric elongation, non-yellowing weathering resistance, and impact toughness, albeit at higher viscosity and formulation costs.

We recommend combining high-functionality epoxy acrylates with reactive mono- and di-functional diluent monomers (such as TPGDA, DPGDA, or alkoxylated TMPTA). Alternatively, Ever Ray's modified low-viscosity epoxy acrylates (e.g., Grade 6300) integrate tailored chain-extenders directly into the prepolymer, decreasing base viscosity without degrading conversion efficiency or inducing shrinkage stress cracks.

Vacuum metallization primers require outstanding gloss, heat resistance during metal deposition, and zero outgassing. Grades like Ever Ray 1730 and 1200A are engineered specifically with enhanced carboxyl/phosphate functionality, delivering 5B cross-hatch adhesion directly onto untarnished aluminum, brass, and dense metal substrates while preventing thermal yellowing during thermal sputtering cycles.

Yes. Our dedicated R&D technical center develops tailor-made molecular architectures. We routinely adjust backbone molecular weights, functionality (ranging from 2 to 6+), acid values, and reactive diluent matrices to suit specific customer lamp spectrums (UV LED 395nm vs. Gallium/Mercury) and end-use performance targets.

UV-curable acrylate resins contain reactive free radicals and active inhibitors (such as MEHQ) which require ambient dissolved oxygen to maintain stability. Resins must be stored in dark, opaque polyethylene or phenolic-lined steel containers between 15°C and 25°C, away from direct sunlight, thermal sources, and strong oxidizers. Stored under correct dry warehouse conditions, stability is guaranteed for 12 months.
