Parabond 1 (PU Adhesive)

Description
PARABOND 1 is moisture setting polyurethane system
for the adhesion of insulation materials on roofs.
Technical Data

Directions for Use
PARABOND 1 is particularly suitable for the adhesion of insulation materials like polyurethane foam, phenol resin foam, perlite sheets, etc. used for roof insulation. Mineralized bitumen, non woven fleeces and coated aluminium laminates can be used as lamination layers. On different substrates PARABOND 1 gives a durable water resistant bond whereby especially the adhesion on sendzimir galvanized sheet is excellent.

PARABOND 1 does not contain chlorinated hydrocarbons and organo metallic compounds.

Substrates
Different concrete qualities and stony substrates mineralized bituminized roofing materials, wood-like materials, galvanized or coated sheet steel, etc. The substrate should be solid, clean, dry and free from material foreign matter.
Bonding on talcumated substrates is not recommendable.

Adhesive Consumption
100 – 300g/m_ depending on smoothness of the substrate and the materials to be bonded. For the border and corner zones the adhesive application requires an extra of approx. 50%.

For adhering mineral wool the usage must be at least 300g/m_. For the border and corner zones the usage is 400 respectively 500g/m².

The adhesive has to be applied in ridges (25 – 75g/m), 4 ridges per metre will mostly be sufficient.

Open time
Do not apply more adhesive than can be covered in max. 5 minutes. The insulation material requires to be laid down and pressed before skin formation sets in. We recommend to check from time to time, by lifting the insulation material at the border side, if the adhesive ridges have been squeezed flat. This is especially important with very uneven substrates.

Setting time The reaction speed of PARABOND 1 is influenced by the following factors:

Temperature;

Thickness of the adhesive ridges

Substrate (moisture containing or non-moisture containing).

The setting time on moisture containing substrates like wood, concrete, etc is at:

5°C – approx. 5 hours

23°C – approx, 2_ hours

The setting time on non-moisture containing substrates like SVS, bituminous etc. is at:

5°C – approx. 8 hours

23°C – approx, 5_ hours

In case of dry substrates and low humidity substrates or covering material should be moistened.

The minimum processing temperature is 5°C.
At low temperature it is recommendable to heat up the containers in hot water to approx. 50°C (do not boil the product).
