KLEIBERIT 501 is a single component PUR adhesive for
strong, gap-filling bonds with high temperature resistance
according to DIN/EN 14257 (WATT 91) and water resistance according to DIN/EN 204 stress group D4.

Fields of application

Bonding windows and doors, stairs, plywood to be used inside or outside (outside use with surface protection).
Bonding mineral building boards, ceramic materials, concrete materials and hard foams.
Please see warnings on the bottle before using!

PREPARATION

The surfaces to be bonded must be climatised, clean, dry and free from dust and grease. Release agents must be completely removed.

APPLICATION

• Single-sided applicationusinga spatula or hand roller to the surface which is least porous
• Assemble the two pieces to be bonded
• The product cures to a water-resistant, solvent-resistant and semi-rigid adhesive film when subjected to the influence of humidity (air, material). The cross-linking process can be accelerated by means of a targeted moisture supply (fine water spray, approximately 20 g/m²), or by higher temperatures (40°C up to max. 60°C).
• The cross-linking process should take place with a pressure that guarantees sufficient contact of the glued surfaces. In order to protect exposed surfaces from being contaminated with glue, apply e.g. a silicone paper to this area.
• The necessary pressure is dependent upon the type and size of materials. A good closed joint should be achieved. Minimum pressure for bonding laminated wood: 0.6 N/mm². The more intensive the cross linking of the adhesive under pressure, the higher the subsequent load ability.
