RENOTECH RT 337
Incombustible Mineral Adhesive
Incombustible Mineral Adhesive
Product Description
Renotech RT 337 is a leightweight, safe, easy to use, fast curing, incombustible, silicate based mineral adhesive. RT 337 adhesive is temperature resistant up to > 1000 °C. It builds up a strong wet adhesion, making a static support during drying, in many cases, redundant. Renotech RT 337 is water based and completely solvent free. Renotech RT 337 is MED approved.
Typical Applications
RT 337 is suitable for bonding mineral based materials, metal, wood and glass. A typical application is the mechanical gluing of various insulation boards. In systems where the water, bound in RT 337 is not able to evaporate (i.e. manufacturing of fireproof doors), it is recommended to add RT 340 as hardener, using a dosage system.
Benefits and Properties
RT 337 mineral adhesive is easily applied using a notched trowe. After application the insulation board is pressed against the substrate by hand for a few seconds in order to develop the necessary wet adhesion.
