HCPE Resin (coating type) Description
HCPE resin (coating type) is a irregular resultant after depth chlorination with the low molecular weight polyethylene (PE) . Generally the quality score of chlorine is bigger than 65%, and it is the main film-forming substances as new generation antiseptic paint. It has the following characteristics.
(1) Compared with the CPVC, the solubility is good, and more resins can mix with it.
(2) Compared with the CSM, the advantage of HCPE is single-component packaging, it do not use lead oxide, tribasic lead curing agent containing heavy metals. There is no toxicity, and has a broader range of applications.
(3) Compared with the chlorinated rubber, HCPE as the base material of protective coatings retains the advantage of chlorinated rubbers, And overcome the faults of chlorinated rubber exist unsaturated double bond and light chemical reaction and chlorinated degradation sensitive.
(4) Compared with ordinary HCPE, the viscosity is low, take the Tu-4 coating cup, the quality score as the toluene solution 20%, under the room temperature determines, is not bigger than 50S; Ordinary HCPE viscosity generally above 50S.
(5) Made of high-solids coatings, reduces the coating cost greatly, and the coating has a fast-drying nature, and has a better compatibility with other resins. LHCPE film features: The coating made by HCPE has a high solid content. excellent resistance to acid, alkali , salt, etc. It have so excellent corrosion resistance properties; can be used under 15~50°C; film drying quickly.
