Liquid polysulfide polymers are versatile pre-polymer resins with water to honey-like viscosity Polysulfide polymers are As SH-terminated grades (Thioplast Gfamily) As epoxy-terminated grades (Thioplast EPSfamily) Cured polysulfide polymers High chemical resistivity Excellent gas barrier properties / low permeability High weather resistance (Low-temperature) flexibility Crack-bridging ability2 Thioplast Polysulfide PolymersThioplast G product family3 Acetal groupsFlexibilization of the polymer backbone; Working temperature: - 55 C +120 C Disulfide linkagesExchange reactions; Stress relaxation; Chemical resistance against oils, fuels, bases, etc. Trifunctional branchingIncreasing the structural toughness and strength Mercaptan end groupsAllow for crosslinking / polymerization via oxidation, NCO- and epoxy-curing; Highly reactive No double / triple bondsHigh weathering-, ageing-, ozone-, UV- and O2stability AvailabilityThioplast G is available in different grades with viscosities ranging from 1 Pas 140 PasThioplast Polysulfides in coatings HowThioplast G helpsto protect4 Thioplast in specialty coatingsApplication example: protective coatings5 Thioplast P
