HRANIPUR 45 - PUR Prepolymer
Product description
It is used for perfect structural bonding. Thanks to its strengthens, water, heat and age resistance it is a perfect to couple surfaces.
Usage:
Bonding:
- wood
- cement fibres
- metals
- sandwiches panels with polystyrene
- polyurethane, PVC
- glass wool
- mineral wool with different coatings
- MDF boards
Characteristics:
Hranipur 45 is a single-component polyurethane adhesive of brown color, which has a wide scope of usage. It’s very strong and it is water and temperature resistant. It hardens after contact with air or humidity of the surfaces to bond.

Application:
The product must be spread on one of the surfaces to bond (the one without varnish/paint); materials must be clean, dry and dust and grease-free. Spread a little cord of adhesive on the surface, couple with the second one and press in a uniform manner; it can be pressed by hand.
Low humidity values increase the setting time; on the contrary, high humidity reduces it. Press time can be considerably reduced by humidifying one of the surfaces to bond. With the rise of the humidity there is also an increase in the foaming.
Mechanical, torsion, traction and pressure tests can be performed after about 24 hours.
While using the product do not place it near free flames or sparks, do not inhale vapours, do not smoke.
We recommend cleaning the adhesive from application tools by Hraniclean 03 (non-hardened adhesive) or Hraniclean 04 (hardened adhesive).
