U-30M liquid polysulfide polymers-based sealant

U-30M 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-30M 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.

Application Characteristics

Application

U-30M liquid polysulfide polymers-based sealant is used for sealing fixed metal (except brass, copper, silver and their alloys) and other joints operating in air, dilute acids, alkalis and fuels. Temperature range is from -60 °C to +130 °C (short-time at +150 °C). For a short time, the U-30M thiokol sealant can be used in the air, but not more than a few hours, since in such conditions the sealant can lose its properties.

The sealant is designed specifically to protect fixed metal parts from high humidity and exposure to ultraviolet rays. Recommended for use in contact with aluminum alloys, non-anodized, magnesium alloys, cadmium plated and bare steel.
