Dalian Bona Biological Technology Co., Ltd.
Modified hydroxyl vinyl chloride - vinyl acetate - ethylene glycol VAH ternary chlorine vinegar resin polymer was made by two steps.Of the modified copolymer composed of vinyl chloride, vinyl acetate, vinyl alcohol.The content of vinyl chloride 90%, roughly 4% of vinyl acetate, ethylene glycol 6%.It can be combined in relatively strong solvents/thinner, such as 50% acetone and 50% aromatic hydrocarbons, produce 25% solid content of resin solution
VAH properties of the resin is with other film forming material has good compatibility.Such as alkyd, epoxy, polyurethane elastomer, isocyanate resin polymer, melamine resin, urea formaldehyde, etc.So often together with other film-forming material preparation, to improve the coating performance, enhance coating adhesion, flexibility, toughness, hardness and chemical resistance.Resin containing hydroxyl groups, it can also provide thermal crosslinking reaction of solid coating system, get better water resistance and chemical resistance.
VAH resin is widely used in coating, gravure ink, chassis paint, industrial paint, wood coatings, ship, paper, paint, paint is the indirect agent and adhesive tape, PET ink, carbon belt.
