HEMA CAS 868-77-9 2-Hydroxyethyl methacrylate
2-Hydroxyethyl methacrylate / HEMA yog cov organic chemical raw khoom, functional additives, tshuaj raw khoom, tshuaj raw khoom txhua hnub. Nws yog tsuas yog siv rau kev hloov kho ntawm resins thiab coatings. Copolymerization nrog lwm cov acrylic monomers tuaj yeem tsim cov acrylic resin nrog active hydroxyl pawg nyob rau hauv cov saw hlau sab, uas yuav siv tau rau esterification thiab cross-linking cov tshuaj tiv thaiv, synthesis ntawm insoluble resin thiab txhim kho adhesion, thiab yuav siv tau raws li tus neeg sawv cev kho fiber. Nws reacts nrog melamine formaldehyde (los yog urea formaldehyde) resin, epoxy resin, thiab lwm yam.
