• Coat weight: 100-200g/m², depending on the condition of the material
• Open time: 25 minutes
• Press time: 60 minutes at 20°C
• Curing time: 2 - 3 hours
• Final strength: after approx. 24 hours with sufficient moisture
• Colour: yellowish-brown

Application

• Single-sided application using a 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 20g/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
