detailed information

BORNIT® Concrete primer is a double-component bonding bridge mainly for polysulphide sealing substances, which is used in the area of floors for treating the internal joint edges prior to the application of BORNIT® cold sealing compound.

Area of use:
As a bonding primer coating on porous, non-absorbent surfaces such as concrete or wood (without a natural finish or topcoat), mainly in the area of floors.

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 period of 30 minutes to 2 hours depending on the temperature), the sealing substance may be poured. The bonding primer should not be completely dry. If the sealing is carried out more than 24 hours later, the primed surface must be roughened and the bonding primer must be reapplied.

Summarised technical data:

Chemical base epoxy resin
Period of workability 2-3 hours
Hardening 30 minutes to 2 hours depending on the temperature
Mixing ratio Component A into component B = 4 : 1 (% by weight)
Consumption 0.01 to 0.02 l/linear metre depending on the dimensions of the joint
Colour colourless, slightly yellow
GISBAU-Productcode RE 2
VOC-content Comp. A < 530 g/l
VOC-content Comp. B < 680 g/l

The storage period, when stored in the closed containers, is 12 months.

Health protection during work and fire protection: 
The components A and B are highly flammable and harmful by inhalation, swallowing, and at skin contact. Keep away from sources of ignition, do not smoke. Wear appropriate protection gloves. Apply larger quantities only in well-ventilated areas. Observe the rules for hazardous materials.

Waste disposal:
Only empty containers may be disposed of. Product waste from components A + B is disposed of according to guideline no. 080409* (glues and insulation materials, which contain organic solvents or other dangerous products).

Method of delivery:
