KASTAR963 is a gun-grade, one component adhesive/sealant based on modified polymers, which cures by reaction with moisture to an elastic product. It is intended for creating flexible and high-strength
sealing and bonding joints resistant to vibration and deformation.
Used in industrial and civil construction and renovation works for sealing and filling vertical and inclined expansion and compensation seams, facade and roof joints, cracks in building panels, and roof constructions. Complies with ISO 11600 Type F Class 25 LM. Has excellent adhesion to most construction materials: stone, brick, concrete, glass, plasterboard, solid plastics (except polyethylene, polypropylene, and fluoroplastic), ceramics, aluminum, metals, composite, stainless steel, and wood. No priming is required. For indoor and outdoor works.
Hybrid adhesive sealant (modern analog of MS-polymers) has high operating characteristics: forms a permanently elastic high-strength and durable joint; is elastic for the whole service life; excellent for joining materials with different temperature expansion. Weather and temperature resistant. Thixotropic, does not flow or drip down the joint. After curing, it is possible to paint with aqueous and synthetic paints (in the case of solvent-based paints, run a test).

Following cleaning procedure and materials are recommended:
Meets or exceeds the requirements of the following specifications:
It must not be used in totally confined spaces where sealant cannot cure due to lack of atmospheric moisture.
Cannot be used on natural stone. Because the adhesion surface will discolor under influence of the sealant (looks wet) and also this is visible through the sealant due to its clear look.
Do not use in applications where continuous water immersion is possible.
Prolonged exposure to direct sunlight can cause discoloring, Joint Width 5mm 10mm Joint Depth 5mm 5mm
