Water soluble or water dispersible reaction products are produced by reacting (1) an epoxy resin having an epoxy equivalent weight of at least about 500 with (2) an organic sulfide in the presence of (3) a protic acid having a dissociation constant greater than 1 × 10. sup.-.sup.5. ...
Study of epoxy resin curing process by applying internal friction technique in the course of chemical reaction between epoxy resin and a hardener. It was shown that the curing reaction is observed as an asymmetrical maximum of ... M Kubisztal,G Haneczok,A Chrobak,... - 《Materials Science...
It was found that chemiluminescence (CL) of epoxy resin proceeds by a two step process. The first step is the formation of a substance causing CL and the second step is its reaction producing luminescence emission. The first step is predominant at room temperature, so that the CL-causing sub...
Physical and Chemical Character: Colorless to light yellow transparent liquid, no irritating odor. HW-630 is a bifunctional, weather-resistant epoxy resin reactive diluent. It participates in the reaction during curing to form chains and networks. When mixed with epo...

Under the chemical aspect, the polymer belongs to the class of epoxy resins and its properties are comparable to those of common thermosets. Generally, epoxy resin consists of two main components: the resin and the hardener. In this case, the resin component is made of native vegetable oils ...
Rosin‐modified o‐cresol novolac epoxy resin (AEOCN) was synthesized by condensation of rosin acid with o‐cresol formaldehyde novolac resin (AOCN). The A... T Thakur,S Jaswal,B Gaur,... - 《Polymer Engineering & Science》 被引量: 0发表: 2021年 加载更多来源...
A thermosetting resin or thermoset is a polymer that cures or sets into a hard shape using curing methods such as heat or radiation. The curing process is an irreversible process. It introduces a polymer network crosslinked by covalent chemical bonds. ...
The effect of the incorporation of nano-Si3N4 on the cure reaction of epoxy resin was investigated by DSC and FTIR analysis.The results showed that nano-Si3N4 could promote the cure reaction of epoxy resin because of its high surface activity,and on the other hand the cure reaction was de...
