Molecular structure of bisphenol A epoxy vinyl ester resin

 

The double bond at both ends of the molecular chain is extremely active, which enables the vinyl resin to solidify quickly, to be used quickly in strength, and to be a highly corrosion-resistant polymer.In the synthesis of methacrylic acid, methyl of ester bond side can protect and improve hydrolysis resistance.The resin contains less ester bonds and is 35-50% less resistant to chemical polyester (bisphenol a-fumarate UPR) per mole, which improves its alkali resistance.More para - hydroxyl can improve the wettability and adhesion of glass fiber and enhance the mechanical strength of laminates.Since the chain is only cross-linked at both ends of the molecule, the chain can elongate under stress to absorb external forces or thermal shock, showing resistance to microcracks or cracking.


Phenolic phenolic epoxy vinyl ester resin

 

The phenolic epoxy resin is introduced into the framework of vinyl ester resin. The synthetic vinyl ester resin is generally called Novolac vinyl ester resin. The specific molecular structure is shown in figure 3.3.The resin has high thermal stability.After curing, the crosslinking density is high.Its thermal deformation temperature of 120-135 ℃, can prolong the service life and excellent corrosion resistance, especially for chlorine solution or organic solvent corrosion resistance is good.
