    sell hydantoin epoxy resin; 1,3-diglycidyl-5,5-dimethylhydantoin polymer

    Imidazolidinedione has lower viscosity than the bisphenol A type epoxy resin, without diluent has a good process performance, can be used as solvent-free coatings, solvent-free adhesive, the photovoltaic element package materials. good thermal stability, high heat resistance. Insulation potting compound can be used at 180 ℃ 5000h above; life at 130 ℃ for 40 years. good weather resistance. Its paint in the sun or UV exposure, the less prone to yellowing and chalking. Superior to a bisphenol A type epoxy resin and the acrylic resin coating. Its resistance to salt spray corrosion resistance is also very prominent, can be used as anti-fouling marine paint covering buildings and ships, adhesives and other building. at high voltage and extra high voltage electric outstanding performance, especially with excellent arc resistanc.
