Take You To Understand Vinyl Resin

Jun 18, 2020

Vinyl resin is recognized as the most corrosion-resistant resin in the world. The standard vinyl resin is synthesized from methacrylic acid and bisphenol A epoxy resin. Vinyl resin has high thermal stability, has a long service life after curing, and has good corrosion resistance, solvent resistance and oxidation resistance, especially for chlorine-containing solutions or organic solvents. So it is usually used under various high temperature and strong corrosion. For example, the anticorrosion of oil storage tanks (see Kebao "Application and Function of Vinyl Resin" for details). There is a detailed introduction on how vinyl resins can achieve the anticorrosion of oil storage tanks.

Vinyl resin has been developed to be flexible at the same time, also to adapt to various anti-corrosion projects, because flexible vinyl ester resin has high adhesion to steel and concrete surfaces, impact strength increased by 4 times, and has unique resistance Abrasive. Generally used for corrosion-resistant lining, caulking material or primer resin, not only improve the overall performance, but also save costs.

If the vinyl resin is modified by urethane, PU modifies the unsaturation in the chain and the unsaturation at the chain end. It has excellent corrosion resistance, flexibility and good processability, which improves the compatibility of resin and fiber, and can maintain a good air-drying on the surface of the resin. Therefore, this type of resin is suitable for various processes of winding.
