Polysulfide rubber features
The polysulfide rubber having a thiol group at both ends and (-sH) is a low molecular weight polymer which has excellent properties such as low temperature flexibility, solvent resistance, stress relaxation and the like. When the polysulfide rubber is mixed with the epoxy resin, the terminal thiol group chemically reacts with the epoxy resin to enter the cured epoxy resin structure, which gives the epoxy resin which is crosslinked and is very flexible. Sex, high shear strength and peel strength. In order to overcome the shortcomings of the reaction rate of the thiol group of the polysulfide rubber and the epoxy resin under the action of no catalyst, the polysulfide rubber may be end-modified with an acrylate and an epoxy group and then mixed with the epoxy.
