1, vinyl resin has the advantages of epoxy resin and unsaturated polyester resin, that is, high strength, chemical corrosion resistance and good process performance.
2. Moreover, epoxy resin has no obvious disadvantages-high viscosity, difficult processing and high cost. Vinyl resin is obtained by the reaction of epoxy resin (such as bisphenol A or tetrabromobisphenol A epoxy resin, epoxy novolak and propylene oxide) and unsaturated monocarboxylic acid (such as acrylic acid and methacrylic acid). Due to the different synthesis processes and methods, the structure, properties and applications of vinyl resins are also different.

connection
Flame retardant vinyl resin is generally synthesized from brominated epoxy resin. Because the resin contains bromine, flame retardant vinyl resin is widely used in epoxy resin.
chemical resistance
And can be flame retardant at the same time.
Can vinyl resin adhere to plastic film? Yes Vinyl resin is a kind of heavy-duty anticorrosive coating vinyl resin, called vinyl ester resin. It is a thermosetting resin of vinyl resin which is formed by melting methacrylic acid and epoxy resin. Vinyl resin The role of vinyl resin is to bond various materials such as pipe fittings, which is itself an adhesive, so it can bond plastic films. Vinyl resin has good toughness, adhesion, chemical resistance, mechanical properties and the most important corrosion resistance.
Is vinyl resin soluble in rosin water? Yes Vinyl resin is a kind of modified vinyl resin which can be diluted with water and dissolved in rosin water. Vinyl resin is an internationally recognized resin with high corrosion resistance. Standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin, which is easily soluble in styrene solution.
