Pressing time (minimum):
Wood on wood at 20°C: 5 - 10 min
Assemblies with one face preheated: 2 - 3 min
Laminates on wood at 20°C: 15 - 20 min
Laminates on wood at 40°C: 8 - 12 min
Stabilisation:
Before machining: 2 hours (minimum)
Complete setting of adhesive: at least 24 hours
SURFACE PREPARATION
- Substrates to be bonded should be perfectly clean, dry and free from dust and grease.
- For laminations, surfaces should be homogeneous and flat.
- Assemblies should be precise in order to avoid thick adhesive lines (0.2 - 0.3mm max.).

- Wood should be allowed to condition for several days in the workshop atmosphere (15 - 20°C) before bonding. Its relative humidity should be approx. 10 - 20%. APPLICATION
- For lamination apply an even coat of adhesive to one of the substrates by roller coater, brush or spatula.
- For assembly applications, we recommend that both surfaces should be coated.
- Coating weight depends on substrate, porosity, open time and ambient temperature.
General features:
Flat lamination: 100 - 240 g/m2
Panelling, edge jointing: 200 - 350 g/m2
Other (motice/tenon, tongue/groove): coat both sides. 
ASSEMBLY
- The parts to be bonded should be brought together immediately after application whilst the adhesive is still wet.
- The maximum open time depends on the substrate porosity, ambient temperature and coating weight. A guideline is given on page 1. PRESSING

- After assembly pressure should be maintaine during the adhesive’s initial setting period, using conventional pressing methods such as presse vices, jigs clamps or dead loads. Refer to the pressure values given on page 1. This is not necessary for finger joints.
- Pressing time depends on such variables as ambient temperature and humidity, coating weight, porosity of substrates and dimensions of assemblies. Reference values are given on page 1 but a test specimen will allow this to be calculated.
- Pressing time can be reduced by heating one substrate to be bonded before pressing at room temperature. We recommend pre-heating of the surface (1 - 2 minutes at 80°C).
- Hot pressing should only be recommended for double sided flat lamination.
GENERAL PRECAUTIONS
- Do not add anything to the adhesive to modify its properties - Provided contact with iron is avoided the adhesive should not cause staining.
- After each use close the container tightly to avoid skin formation.
- Coating equipment and tools can be cleaned with warm (35 - 40°C) water, before the adhesive has dried out.
- For health, safety and disposal please refer to the material safety data sheet.
