Detailed Information

BORNIT® Asphalt Primer is a double-component bonding bridge for the polysulphide BORNIT® Cold Sealing Compound, which is mainly used on problematic bases or for special application areas.

Area of use:
BORNIT® Asphalt Primer can be used on absorbent and non-absorbent bases. Its excellent gripping properties can be used, for example, on freshly cut bitumen and on various metal surfaces (stainless steel, brass, aluminium and so on). BORNIT® Asphalt Primer is especially suitable as a bonding bridge in cases where heat loading of up to +100°C can be expected.
It is not suitable for bitumen surfaces, which will subsequently be loaded with chemicals such as petrol, diesel and so on.

The base must be dry and free of dust, grease and loose particles. Components A + B are mixed and the bonding primer solution is applied uniformly onto the base using a brush. After it has dried (a minimum of 6 hours) the sealing substance may be poured. The bonding primer should not be completely dry. If the sealing is carried out on the following day, it is necessary to verify whether a water film has formed on the surface as a result of the dew point.

Summarised technical data:
