Investigating of polysulfide and epoxy‐polysulfide copolymer curing

Materialwissenschaft und Werkstofftechnik, 2010
AbstractPolysulfide can be cured in various methods. In this work, the effect of various oxidative curing agents (manganese dioxide and para quinonedioxime) in presence of curing accelerator (Diphenylguanidine) on mechanical‐dynamical properties and cure time of polysulfide resin (G4) was investigated.

Polysulfide Sealants

Rubber Chemistry and Technology, 1981
Abstract Sealants based on polysulfide liquid polymers are widely used in a number of applications. These sealants are solvent and chemical resistant, having good flexibility and adherence to many substrates such as steel, aluminum, glass, concrete, wood, etc.

Polysulfide Polymers

Rubber Chemistry and Technology, 1950
Abstract The chemistry of the condensation polymerization is reviewed briefly. The structures of the polymeric products as well as the effects of copolymerization, cross-linking, end groups, and molecular weight upon polymer properties are discussed.

Modification of polysulfide sealant with polysulfide polythio‐urethane‐urea

Journal of Applied Polymer Science, 2007
AbstractWith a small amount of isocyanate‐terminated polysulfide (NCO‐PSF‐NCO) as additive, the commercial polysulfide‐based sealant had significant improvement in mechanical properties. The test results showed that 5% of NCO‐PSF‐NCO could help to rise 50% in the tensile strength and 27% in the ultimate elongation of the polysulfide sealant.
