Open time

Open time at 20 °C:
Consumption 100 g/m2, min ~6
Consumption 200 g/m2, min ~15

Temperature and standard pressing time

Pressing temperature, °C Pressing time, min
At 80-90 °C ≥5
At 90-95 °C ≥4
At 95-100 °C ≥3
At 100-105 °C ≥2,5
At 105-110 °C ≥2
At 110-115 °C ≥1,5

Necessary time of pressing: standard time, plus 1 minute for each mm of veneer thickness.

The working temperature of the adhesive and the workpiece must be at least +10 °C.

Working temperature

Depending on the type and thickness of veneer, 140-170 °C for splicing machines:

  • With 0.8 mm veneer thickness: ~145 °C
  • With 0.3 mm veneer thickness: 150-170 °C

Mixing

Ready-to-use adhesive mix:

  • 1 volume part water: 10 kg water.
  • 3 dimensional parts AQUENCE FU 424: 18 kg of AQUENCE FU 424

Preparation of adhesive mortar:

First, pour water into the mixing tank. Then add the glue powder until you obtain a creamy consistency without lumps. You can use any available mixing equipment.

Time life

Life time depending on ambient temperature, at 20°C: ~8 h

Usage

The edge of the veneer is covered with glue roller, and then the glue is dried. For drying veneer with fresh adhesive should be spread out like a fan.

Processing

Bonding veneers with adhesive prednnisone comes at the expense of thermoactivation in the press.

Clean up

Cleaning painting equipment from uncured adhesive residues, it is possible to produce cold or warm water. Hardened residues are removed mechanically.

Storage of adhesive melt Henkel AQUENCE FU 424

Storage life up to 9 months without significant loss of adhesive properties. The opened inner plastic bag must be tightly sealed to prevent the powder from coming into contact with moisture.
