The word anti-corrosion has almost become the mantra in today's chemical and construction industries, all kinds of anti-corrosion materials are also emerging in the market. Vinyl resin is one of the representatives of anti-corrosion materials, for different areas of anti-corrosion project has made its contribution. Vinyl ester resin material is internationally recognized as a highly corrosion-resistant resin, is an authoritative anti-corrosion materials. Different types of vinyl resins have different applications,
Vinyl ester resins on the domestic market according to different properties can be classified as follows:
1, the standard bisphenol A epoxy vinyl resin: can be quickly cured, the use of high strength, corrosion resistance, hydrolysis resistance, alkali-resistant polymers; because of its special synthetic materials to make this kind of Vinyl ester resins also have a better flame retardant type.
2, Vinyl ester resin: Phenolic epoxy resin is introduced into the framework of vinyl ester resin, synthetic vinyl resin. Has a high thermal stability, crosslinking density, long service life and has excellent corrosion resistance and oxidation resistance, suitable for a variety of high temperature and strong corrosion.
3, acrylic vinyl ester resin: This type of vinyl resin temperature rating than the corresponding methacrylate-type vinyl ester down 10-20 ℃, the elongation of the resin.
The above is based on the composition of vinyl resin classification, but also according to their functional properties will be divided into vinyl resin: low shrinkage vinyl resin, impact-resistant vinyl resin, thickening vinyl resin, photosensitive vinyl resin and gas Dry vinyl resins. Different types of vinyl resin outstanding performance varies, play a role and application are not the same.
