ALFO DG 45

• Fast setting
• Humidity resistant
• Specially designed for short press times

SURFACE PREPARATION

Substrates to be bonded should be perfectly clean, dry and free from dust and grease.

For lamination, both 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.

Flat lamination: 100 - 240 g/m2

Panelling, edge jointing: 200 - 350 g/m2

Other (mortise/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.

PRESSING

After assembly pressure should be maintain during the adhesive’s initial setting period, using conventional pressing methods such as press vices, jigs clamps or dead loads.  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. Pressing time can be reduced by heating one substrate to be bonded before pressing at room temperature. We recommend preheating of the surface (1 - 2 minutes at 80°C).

Hot pressing is only recommended for double sided flat lamination.

Laminates on wood at 40°C: 8 - 12 min

Stabilisation:

Before machining: 2 hours (minimum)

Complete setting of adhesive: at least 24 hours

Do not add anything to the adhesive to modify its properties. Provided contact with iron is avoided the adhesive should not cause staining.
