POLYSULFIDE PRODUCTION 

1. POLYSULFIDE OLIGOMERS 

(STATE STANDART 12812-80, TU 38.50309-93) 

Description 

Liquid polysulfide oligomers (LPO) – sulfur containing reactive oligomers with active terminal groups. A viscous homogeneous dark liquid with greenish or brownish shade, without foreign inclusions and with peculiar smell of mercaptans. 

Application 

Liquid polysulfide oligomers are intended for manufacturing of sealants, which are used in aircraft industry, shipbuilding, electrical industry, electronics and civil engineering. 

Specific properties 

LPO are resistant to the action of oils, fuel, acids, alkalis, ozone, sun rays and radiation. LPO are highly gasproof, nonexplosive, incombustible, nontoxic materials. 

Packaging 200 liters in barrel 

Shelf life 3 years

2. SEALANTS BASED ON POLYSULFIDE OLIGOMERS U-30MES-5, UT-32 (TU 38.1051386-80), U-30MES-5NT, UT-32NT (TU 38.605462-91), UT-34 (STATE STANDART 24285-80), U-30MES-5M (TU 38.1051436-88), VITEF-1NT (TU 38.1051291-84), U-30M (STATE STANDART 13489-79) 

Application 

U-30MES-5, U-30MES-5NT, UT-32NT, U-30MES-5M, VITEF-1NT are intended for: 

- Surface and inner sealing of riveted, welded and bolted joints, aircraft constructions, devices and other products; 

- The repair of aerospace equipment. 

UT-32, UT-34 are intended for: 

- Sealing of riveted, bolted and other mechanical joints; 

- Plug-in connectors, fuel compartment, pressurized input sealing. 

U-30M – general purpose sealant, for sealing metal (except brass, copper, silver and their alloys) and other joints, working in air, dilute acids, alkalis and fuel. 

Properties 

Sealants are characterized by good deformability, high oil, petrol, UV, oxygen resistance, moisture and air impermeability. Sealant are recommended to use in contact with the aluminum alloys, non-anodized, magnesium alloys, cadmium plated and exposed steel. Sealants based on polysulfide oligomers are three-component compositions, consisting of a basic (sealing), curing pastes and catalyst. Sealants are capable of vulcanizing at a temperature not lower than 18oC, UT-34, 4-30MES-5M, U-30M – not lower than 15oC.
