One-component, elastomeric, adhesive and sealant, based on hybrid polymer resins. It offers:

• Resistance to temperature fluctuations from -40 oC to +90 oC.
• Excellent bonding to any kind of building material.
• High elasticity.
• Great resistance to aging and weather condition.
• Adhesion to wet substrates (even without priming). 
• Good resistance to fungi growth.
• Overpaintability after hardening.

FLEX MS-45 is suitable for sealing vertical and horizontal joints (3-40 mm wide), both indoors and outdoors, between materials like glass, aluminium, wood, granite, marble, PVC, etc. Also suitable for elastic bonding on various substrates. Not recommended for joints immersed into water or in direct contact with food products. In case of grouting on natural or artificial stones, such as marble and granite, please contact ISOMAT’s Technical Support Department.

Substrate preparation
Substrate must be free of dust, loose particles, grease, etc. The joint should be cleaned with a paintbrush or wire brush and then air-blasted. To avoid undesirable soiling at joint edges, a self-adhesive paper tape is applied along the edges and then removed immediately after sealing the joint (before a film is formed).

Application
The cartridge is inserted in the special gun and the nozzle is cut slantwise, so that it does not fit into the joint but barely touches and slides along the edges. FLEX MS-45 is applied by moving the cartridge along the joint axis at a 45 o angle. While still fresh, the sealant is smoothed out with a trowel.
Cleaning of tools:
Tools must be thoroughly cleaned with common solvents while the material is still fresh. If the material has hardened, tools may only be mechanically cleaned.
