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.

Hard combustible sealant Abris Stg-B 260/320 in cartridges

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).

  • Adaptability (mastic is ready for use, convenient to use);
  • Good adhesion to building materials (metal, concrete, foam concrete, glass, foam glass, brick, plastic, PIR, etc.).
  • Maintainability;
  • High plasticity;
  • Environmental safety;
  • Excellent self-adhesive properties;
  • Wide operating temperature range;
  • Preservation of sealing properties during vibration loads;
  • Durability.

 

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.
