Hard combustible sealant Abris Stg-B 260/320 in cartridges
Section: tubes (cartridges)
Packaging: cartridge
TU: 5572-003-43008408-99
High-quality hard combustible one-component sealant based on butyl rubber. The sealant Abris Stg-B260/320 is a mastic-polymer mass of gray color, packed in cartridges for a hand gun for applying sealants. It can also be produced in metal sealed buckets.
The sealing material has a good self-adhesive ability to any dry surfaces and high anti-corrosion properties. It is characterized by high physical stability when exposed to temperature changes and weather factors.
- Hard combustible properties (does not support burning after drying);
- resistance to negative temperatures — up to minus 180 °C;
- progressive packaging in cartridges (can be produced in metal sealed buckets);
- modern technology of application with a construction gun.
Scope of application:
The sealant Abris Stg-B260/320 is designed for sealing joints in structures made of various materials (metal, concrete, foam glass, brick, etc.) in buildings and structures of all types.
Specifications:
Base color: gray
Product form: cartridges (can be produced in sealed buckets).

Instructions for use
Used equipment, tools, materials:
- construction gun for sealant;
- knife or scissors;
- rags.
Preparation of the sealant: The sealant is completely ready for use and does not require preheating. It has increased plasticity and stickiness to cold surfaces in conditions of negative temperatures up to minus 20 °C.
Surface preparation: Clean the work surface from dust, dirt, ice and dry it. Remove the exfoliated outer layer of rust from the rusty surface.
Applying the sealant:
Take the cartridge Abris Stg-B 260/320 from the box. Cut the cartridge nozzle at an angle of 45 °C to the required size (but not less than 5 mm). Use a hand gun to apply the sealant to the work surface.
Storage conditions of the sealant: Store in a dry room.
Safety measures: When working with Abris Stg-B 260/320, no special protective equipment is required for workers.
