Sealant Viksint VGO-1
Silicone-organic silicon sealant of the type "Viksint" VGO-1
TU 38.303-04-04-90
The most valuable feature of siloxane materials is the stability of the properties of performance characteristics during long-term operation under conditions of sharp temperature changes, increased vibrations, tropical climate, UV irradiation, and radiation resistance.
This determines the application of sealants. Sealants are used in the aviation industry, rocket and space industry, instrument making, radio electronic industry, shipbuilding, automotive industry, civil engineering, industrial construction.
Characteristic:
Silicone one-component sealant VGO-1 is a pasty material that has the ability to vulcanize with air moisture at room temperature, passing into a rubbery state.
The sealant does not cause corrosion of metals and alloys.
Setting time from 10 minutes.
Full cure of the sealant occurs within 24-48 hours.
Color: white.
Mode of application:
Apply the sealant to a 1-3 mm thick degreased with gasoline, acetone or alcohol, at a temperature of +15 ÷ + 35°C.
Connect the surfaces and lightly press against each other.
After applying the tube tightly closed.
PACKING: Sealant VGO-1 is supplied in tubes 200 g and cartridges 600 g.
The warranty period of storage in the tube is 1.5 years at a temperature of 0°C to + 30°C.
Sealant VGO-1 is intended for:
• for surface sealing of metal joints and for sealing structures, instruments, equipment, resistors, various products of radio electronic equipment operating in the air at temperatures from -60 to +250 (for short periods 300) ºС;
• for sealing the joints of the external panels of freezing and refrigerating chambers, heating appliances;
• for gluing glass, concrete, wood, ceramics, metals;
• for sealing threaded and riveted joints;
• for the repair of products sealed with “Viksint” sealants.
