Phenolic vinyl ester resins such as CHEMPULSE 907, 907-S, 900, 977-S, a phenolic epoxy modified vinyl ester resin, has a high crosslinking density after curing, which makes it have a good resistance to oxidizing acids and strong corrosive organic solvents. At the same time, it is endowed with extremely high HDT, which can be used in some high temperature occasions, such as the preparation of high temperature flue and smoke pipe.
