Product Description

Vinyl Ester Resin INV-V470

Product Description

Brief introduction:
INV-V470 is a novolac epoxy vinyl ester resin with the following characteristics:
1. Moderate reactivity, suitable for hand lay-up, pultrusion, winding and other molding processes;
2. Medium viscosity, good curing characteristics, high curing degree of products;
3. High toughness, crack resistance, high heat resistance temperature, excellent strength retention rate at high temperature.

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.
