UT-34 liquid polysulfide polymers-based sealant
UT-34 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). UT-34 sealant is capable of curing at a temperature not lower than 15 °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, UT-34 sealant is resistant to crude oil, oil products, solutions of acids, alkalis, salts and solvents. The sealant is efficient in the temperature range from -60°C to +130°C. The sealant must not come into direct contact with silver, brass or copper contacts.
UT-34 liquid polysulfide polymers-based sealant is designed for sealing riveted, bolted and other mechanical joints; feedthroughs, plug connectors, fuel compartments
