Vinyl resin fiberglass resin, unsaturated polyester resin acid corrosion

Vinyl ester resin, also known as vinyl resin. Vinyl resin application areas: 1: make corrosion-resistant FRP products such as FRP tanks, pipelines, towers and sheds and other corrosion-resistant cells. 2: anticorrosion, such as cement-based or iron-based FRP Lining, highly corrosion resistant flooring, high strength FRP products. Such as glass, steel profiles, sports, FRP boats and the like. 3: Heavy-duty glass flake paint, clay flake. 4: others such as UV inks, and other heavy-duty industrial floor. 5: power plant desulfurization corrosion, high temperature resistance, acid and alkali. 6: acid corrosion and other chemical workshop bench. Name: Vinyl Resin Specifications: 220KG / barrel can bulk Price: 29 yuan / KG Features: vinyl resin (Vinyl Ester Resins) is an internationally recognized highly corrosion resistant resin. Standard bisphenol A epoxy vinyl resin is a methacrylic acid and bisphenol A epoxy vinyl resin synthesized by, has been dissolved in styrene solution, the type of resin has the following characteristics: 1, in the molecular chain end of the double bond is extremely lively, vinyl resins rapidly cured quickly using the strength to give a polymer with high corrosion resistance; 2, methacrylic acid, methyl ester bond side may play a protective role, improving the water solvability; 3, a resin containing an ester bond is less, per mole ratio of chemically resistant polyester (bisphenol A- fumarate UPR) 35-50% less to improve alkali resistance; 4, more secondary hydroxyl groups can glass fibers to improve wettability and adhesion, improving the mechanical strength of the laminate; 5, since only the ends of the cross-linking molecule. Commonly used brominated flame retardant epoxy vinyl resin synthesis, the resin due bromine, therefore, while the flame retardant vinyl resin having chemical resistance, but also flame retardant. Vinyl ester resins in the domestic market in addition to the above species, there are two major categories: one is more acrylic vinyl ester resin manufacturers use, or on the basis of the modified resin was treated with urethane, the type Resin temperature levels down from the corresponding methyl acrylate vinyl ester 10-20 ℃, elongation resin rose, but the lack of the protective effect of methyl ester bond, resulting in the corrosion resistance of the resin, such as alkali resistance can fall; Another resin is our specialty products, which are fumaric acid-modified bisphenol A epoxy vinyl ester resin, but said that in the strict sense, it does not belong to the vinyl ester resin, vinyl ester resin with bisphenol but A unsaturated polyester resin in a transitional species, this type of a vinyl ester resin having a high crosslinking density, brittleness and shrinkage characteristics of a large, since the resin is an ester bond content than standard vinyl resin 40-50 %, so the alkali resistance is relatively poor.
