U-30MES-5NT liquid polysulfide polymers-based sealant

U-30MES-5NT liquid polysulfide polymers-based sealant

U-30MES-5NT liquid polysulfide polymers (thiokol)-based sealant is a composition consisting of three components: base (sealing) paste, hardening (curing) paste, and a curing accelerator. After mixing the components, the sealant irreversibly transitions into a black rubber-like material (other color shades are not possible). U-30MES-5 sealant is capable of curing at a temperature not lower than 18 °С. Thiokol sealants feature good deformability, high oil and petrol resistance, good resistance to UV radiation, oxygen, moisture and air impermeability. Due to its liquid polysulfide polymer base, U-30MES-5NT sealant is resistant to crude oil, oil products, solutions of acids, alkalis, salts and solvents. Sealant with “NT” index is supplied to the aviation industry enterprises
