Vinyl Ester Resin

Application:

This resin is used to make FRP composites and pipes and tanks. It is also used to produce gel coat or coatings that are exposed to corrosive and severe conditions.

Product Introduction:

Vinyl ester resins based on bisphenol A consist of a diglycidyl ether structure that has reacted with unsaturated monoacids (usually acrylic acid) at both ends. In this way, this resin has unsaturated functionality at its two ends. This resin is mixed with a reactive diluent, and this reactive diluent is usually vinyl monomers and specifically styrene. The curing process is done through the chain polymerization reaction of unsaturated agents. Before use, the investigated resin is mixed with mainly peroxide initiators and accelerators and is cured in a limited time. Vinyl ester resin is cheaper than epoxy; However it is more expensive than unsaturated polyester.

Technical Specifications:

In terms of functionality and physical-mechanical properties, this resin has average properties between unsaturated polyester and epoxy. The solid percentage of this product is measured based on the ASTM D1259 standard, which is usually more than 50%. The gel time also varies depending on the final application; But it is usually less than 30 minutes. In addition, the tensile strength (based on ISO 527-2 standard) and bending strength (based on ISO178 standard) are more than 50 MPa and 100 MPa, respectively. The final color of the product should be measured by Gardner’s standard and depending on the precision of the synthesis method and the selection of suitable factors, it can be reduced to less than 1, which is reduced to about 2 in this product.
