KLEIBERIT 301.2 

Water resistant PVAC 

Glue for bonding in accordance with DIN EN 204, stress group D3 

Fields of use 

  • Bonding windows and doors 
  • Surface bonding of HPL boards 
  • Brush, spatula or glue roller 
  • Gluing devices fitted to frame presses and dovetailing machines 
  • Glue spreading machines 
  • Surface bonding during partition and element manufacture

Advantages 

  • As a single component glue – ready for use 
  • Suitable for hot and cold bonding 

Properties of the bond 

  • KLEIBERIT 301.2 meets the requirements of the DIN/EN 204, bond quality D 3;
     i.f.t. test report no. 16-002494-PR02 dated 26/08/2016
  • High bond strength, also with hard and exotic timbers 
  • Glue line: tough elastic, colourless 

Properties of the glue 

Base: PVAC dispersion
Density at 20 °C: approx. 1.10 g/cm3
pH-value: approx. 3
Colour of glue: white
Consistency: medium viscous
Viscosity at 20 °C – Brookfield RVT Sp 6/20 rpm:  15,000 ± 3,000 mPa·s
Pot life: approx. 24 hrs with hardener added
Open time (at 20 °C): 6-10 minutes
Chalk point: approx. +5°C
Identification: Identification not required according to EU regulations. (See our safety data sheet)

Application methods 

  • Brush, spatula or glue roller
  • Gluing devices fitted to frame presses and dovetailing machines
  • Glue spreading machines

Application devices must be made from V2A steel or synthetic materials.

Application techniques

The materials to be glued must be free from dust, oil and grease, and be acclimatised. The most favourable working temperature is 18-20 °C and the moisture content of the wood should range between 8-10% for indoor areas and 10-14%  for window production.
Do not process blow +10°C.

In most cases, single-sided glue application is sufficient. Double-sided application is recommended for hard and exotic timbers!

Application quantity: 

100-130 g/m2 for veneer work.
150-200 g/m2 when bonding solid wood
The application quantity is dependent upon the structure of the surface and the application devices used.

Open time:

6-10 min. The open time is influenced by the quantity of glue applied, absorbability of the materials, temperature and the moisture content of the wood and air.

Pressure:  0.70-1.00 N/mm2 for laminates and laminated wood.

Depending on the type of wood and the surface properties a further waiting time of 2 hours might be necessary before further processing. 

Final bond strength which meets the requirements of DIN/EN 204 will be reached after 7 days. 

Wood and wooden materials are natural products. Influenced by the region of the world from which they originate, as well as the differing pre-treatment methods to which they have been exposed, isolated cases of discolouration, (e.g. Birch, Cherry and Sugar Maple) can occur. The same can happen when bonding wood which contains tannin (e.g. Oak) and when it makes contact with iron (due to an unsuitable pressing plant).

Cleaning

Application devices, machines and containers can be cleaned with water.
