HEMA CAS 868-77-9 2-Hydroxyethyl methacrylate
2-Hydroxyethyl methacrylate / HEMA ndeye organic kemikari mbishi zvinhu, zvinoshanda zvekuwedzera, kemikari mbishi zvinhu, zuva nezuva kemikari mbishi zvinhu. Inonyanya kushandiswa kugadzirisa resins uye machira. Copolymerization nemamwe ma acrylic monomers anogona kugadzira acrylic resin ane anoshanda hydroxyl mapoka ari padivi cheni, iyo inogona kushandiswa esterification uye muchinjika-inobatanidza kuita, synthesis isinganyungudika resin uye kuvandudzwa kwekunamatira, uye inogona kushandiswa sefiber kurapwa agent. Inopindirana ne melamine formaldehyde (kana urea formaldehyde) resin, epoxy resin, nezvimwewo kugadzira maviri-component coatings.
