detailed information

Areas of application
BORNIT® Bitumen Adhesive is designed for adhering roof membranes in the form of sheets and other roof coverings to roof pitches up to 12.5 %. BORNIT® Bitumen Adhesive adheres to concrete, masonry, plaster, bitumen roofing felt and other common roof membranes. Prior to application on concrete, masonry and plaster, prime the substrate with BORNIT® Bitumen Primer for pore wetting. In case of old, weathered roof membranes, priming with BORNIT® Bitumen Primer is essential! Bornit Bitumen Adhesive is not suitable for adhering polystyrene products and for bituminous sheeting!
BORNIT® Bitumen Adhesive must not be directly applied to wooden roof boarding as well as lathing or permeable substrates! In this case, suitable bituminous roof sheeting (e.g. V 13) must be nailed down in order to prevent leakage or penetration, resp., of the material at high temperatures.

Type and properties
BORNIT® Bitumen Adhesive is a cold workable , spreadable, medium-viscosity, bitumen-solvent-based adhesive with
out fillers. BORNIT® Bitumen Adhesive has been tested according to works standard.

Product advantages
•    Economical and cost-reducing as there is less equipment, material and labor
•    no seams
•    ready for use
•    Can be processed cold

The substrate must be dry and free from dust or other contaminations. For mineral substrates and in case of heavily weathered roof membranes, use BORNIT® Bitumen Primer for priming.

BORNIT® Bitumen Adhesive can be used without heating and dilution. BORNIT® Bitumen Adhesive must be stirred up prior to processing! During processing, the product should have a temperature of min. +20 °C. The processing temperature (ambient and substrate temperature) should not be below +5 °C and not above +35 °C.
