High Toughness Epoxy Vinyl Ester Resin for BMC, SMC, Molded Products

Product Description

Vinyl Ester Resin INV-V495Product Description
Properties:
INV-V495 is a high-strength and high-toughness vinyl ester resin that can be thickened with MgO. It can be used together with a low-shrinkage agent to meet the requirements of low shrinkage, high strength, high toughness, high heat resistance and heat aging resistance. It is suitable for BMC and SMC. , Pre-impregnated sheet and other molded products are formed, and the products maintain high strength retention rate and broad-spectrum acid, alkali, solvent and other media corrosion properties at higher temperatures.
Brief introduction:
Epoxy vinyl ester resin is prepared by the chemical reaction of epoxy resin and methacrylic acid through ring-opening addition. It retains the basic segment of epoxy resin, and has the good process performance of unsaturated polyester resin. After curing under suitable conditions, it shows some special excellent properties.
Matters needing attention:
1. The transportation shall comply with the regulations on the transportation and handling of hazardous chemicals in Chapter V of the State Council's "Regulations on the Safety Management of Chemical Hazardous Substances".
2. The product should be stored in a cool place below 25ºC, avoid fire and isolate the heat source.
3. The shelf life is 3 months under the specified storage conditions.
Features:
The standard bisphenol A epoxy vinyl resin is a vinyl resin synthesized by the reaction of methacrylic acid and bisphenol A epoxy resin. It has been dissolved in styrene solution. The specific molecular structure is shown in the figure below.
