The Standard Bisphenol Epoxy Vinyl Resin Synthesized by The Reaction of Methacrylic Acid

Product Description

Vinyl Ester Resin INV-V411MProduct DescriptionBrief 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.
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.
This type of resin has the following characteristics:
(1) The double bonds at both ends of the molecular chain are extremely active, so that the vinyl resin can be cured quickly, and the strength of use can be quickly obtained, and a polymer with high corrosion resistance can be obtained;
(2) It is synthesized by methacrylic acid, and the methyl group on the edge of the ester bond can play a protective role and improve the hydrolysis resistance;
(3) The resin contains less ester bonds, which is 35-50% less per mole than chemical resistant polyester (bisphenol A-fumaric acid UPR), which improves its alkali resistance;
(4) More secondary hydroxyl groups can improve the wettability and adhesion of glass fibers, and improve the mechanical strength of laminates;
(5) Since it is only cross-linked at both ends of the molecule, the molecular chain can be elongated under stress to absorb external force or thermal shock, showing resistance to micro-cracking or cracking.

What is resin?
Resin usually refers to products inclined to softening or melting after receiving heat. When softening, it shows a trend toward flowing under the influence of external forces. Under normal temperature, it is in solid, semi-solid state, and sometimes liquid organic polymer. Broadly speaking, any macromolecule compound that can be used as a raw material for plastic processing can be called resin.
What can resins do for you?
