How Much Do You Know About The Characteristics Of Vinyl Ester Resin?

Jun 17, 2020

1. Super corrosion resistance

All the components of vinyl ester resin participate in crosslinking and curing, no small molecular substances are precipitated, the crosslinking density is high, and the cured product is dense and solid; the content of ester bond is low, which is resistant to acid and alkali, and has certain oxidizing medium and organic solvent. Resistance; its superior corrosion resistance has been proven in many areas of corrosion protection.

2. Good mechanical properties

The vinyl ester resin has good mechanical properties after curing, the pure resin casting has a bending strength of more than 120MPa, a tensile strength of 80MPa, and a tensile elongation at break of 4% to 8% (specially toughened vinyl ester resin Elongation rate can reach 8%~20%). After being reinforced by fibers or other reinforcing materials, its mechanical and mechanical properties are better, and it can be used as a corrosion-resistant lining layer or cement material, or as a whole structural part.

3. Good construction process performance

The characteristics of low viscosity, curable at room temperature, large controllable range of gel time, strong adhesion to the substrate, and good fiber impregnation all give vinyl ester resin good construction processability.

4. Molecular structure designability

By changing the molecular structure of the epoxy compound and acid in the vinyl ester part and changing the type and content of unsaturated polymerizable monomers, it is possible to design the molecular structure of the vinyl ester resin in a targeted manner to achieve different crosslinking density and toughness , Strength and other requirements.

5. Complete varieties and wide application fields

Vinyl ester resins are divided into various grades and types according to different molecular structures, different properties, and different applications, such as acrylic vinyl ester resins, methacrylic vinyl ester resins, phenolic vinyl ester resins, and brominated Flame retardant vinyl ester resin, high crosslink density vinyl ester resin, polyurethane modified vinyl ester resin, rubber modified vinyl ester resin, partially esterified vinyl ester resin, thickened bisphenol A type Vinyl ester resin, thickening phenolic vinyl ester resin, thickening and toughening vinyl ester resin, primer vinyl ester resin, marine vinyl ester resin, food grade vinyl ester resin, low shrink vinyl Ester resin, low styrene volatile vinyl ester resin, o-cresol novolac epoxy acrylate resin, two (four, six) functional polyurethane acrylate resin, rapid pultrusion vinyl ester resin for high heat resistance bending, Vinyl ester resin for low odor (styrene volatilization) floors, chlorobridge acid modified flame retardant high corrosion resistance heat resistant vinyl ester resin, etc. The application form of vinyl ester resin in anti-corrosion also covers all coating and resin anti-corrosion forms-coating, cement, mortar, polymer concrete, glass fiber reinforced plastic lining, glass steel, brick lining, etc.; in non-traditional anti-corrosion fields, such as Flame-retardant materials, fiber-optic cable reinforcement cores, helmets, fishing rods, sports equipment, anchors, high-speed rails, yachts, railway track gaskets, electrical insulation materials and other fields have also been widely used.
