EPB Contact bonding 2.5ltr

1. Description - The Firestone RubberCover™ Bonding Adhesive BA-2012 is a solvent based contact adhesive designed specifically for bonding Firestone RubberCover EPDM membranes to approved insulations in addition to wood, metal, masonry and other acceptable substrates
2. Preparation - Surfaces that will receive the RubberCover Bonding Adhesive BA-2012 must be clean, smooth, dry and free of sharp edges, loose and foreign materials, oil, grease, and other contaminants. If necessary, the mating surface shall be cleaned with a brush or clean rag. Remove any moisture or contaminants from the surface before applying the adhesive. Restore the adhesive to room temperature (15°-25°C) before use if the product has been exposed to temperatures below 10°C for a prolonged period. Stir the adhesive thoroughly to achieve a uniform mix with no sediments on the bottom and no marbling evident before and during use.
3. Application - Apply RubberCover Bonding Adhesive BA-2012 at about the same time onto both surfaces to be adhered, in order to allow approximately the same drying time. The adhesive can be manually applied using a solvent resistant roller. Apply RubberCover Bonding Adhesive BA-2012 evenly, avoiding areas of accumulation onto the mating surfaces. When applying RubberCover Bonding Adhesive BA-2012, ensure complete uniform coverage of both surfaces to be adhered. Application temperatures may vary between 5°C and 35°C. At temperatures below 10°C, the adhesive may become too cold, while at temperatures above 35°C the membrane surface may become too hot and will shorten significantly the drying process. Allow the adhesive to flash off until tacky (time depending on ambient air conditions) before mating the surfaces. Test the adhesive for its dryness, using the touch-push test procedure. Refer to the Firestone guidelines for specific installation instructions.
4. Coverage - Coverage rates depend on the nature of the substrate. ▪ Roller application: 2.35 to 3 m² of surface (two sides) / Liter Some surfaces are uneven and porous and will result in lower coverage rates, while smoother substrates are less porous and will, therefore, result in higher rates. Very porous substrates (rough wood, concrete block) may require an additional coat of adhesive to ensure proper adhesion. This can be determined by adhering a small piece of membrane to the substrate and verifying its bonding strength.
5. Characteristics ● Excellent resistance to ageing ● Good resistance to heat and cold ● Excellent tack time for versatility of installation ● Outstanding adhesion to approved substrates
