Density 1.09 g/cm3, the product does not contain mineral fillers
A filled product can have a density of up to 1.30 g/cm3
A large amount of glue is applied, so as a filled product for manufacturing, consumption is around 25% higher
In a canister, a filled product occupies 70–75% of the volume, while an unfilled product occupies 90–95%
The colour of the glue is greyish or yellowish in filled products
Filled products tend to leave a grey line of glue
PVA glue with high adhesive power, for indoor gluing
Once the glue has hardened, it becomes semi-transparent without undergoing any discolouration
Strong, elastic adhesive line
With class D4 hardener, in accordance with EN 204/205
- Polyisocyanate-based hardener
- To catalyse D3 glue to D4 class. Add hardener for PVA glues to achieve class D4 resistance to long and frequent exposure to water and atmospheric agents
Compliant with EN 204/205, D3 and WATT 91 standards
Caution with woods containing tannin!
On wood containing high levels of tannin, the glue line may be coloured (chestnut, oak) a problem accentuated by the presence of iron
Protect from frost!
Do not apply below 6/10°C
Gluing at temperatures below 15°C may be ineffective
Storage at temperatures below 5°C and above 35°C can damage the product
With the higher temperatures in the summer months, the open time is significantly reduced
While based on our best experience, the technical advice given should be considered purely as guidance, and must be confirmed through comprehensive practical tests. It does not relieve the purchaser of their responsibility to personally test our products to see whether they are suitable for the intended use
Compliant with EN 204/205, D3 and WATT 91 standards
Recommended where frequent and prolonged exposure to water, condensation and ambient humidity is possible
Suitable for: windows, bathroom cabinets, kitchen cabinets, doors
Hot and cold bonding of softwood, hardwood, resinous wood: fir, pine, poplar, beech, oak, cherry, walnut, chestnut
Solid to particle board and particle board to particle board
Laminates and finishing, hot and cold
External parts must be protected from direct weathering
Mix well before each application. Apply glue evenly with a glue roller, brush, dispenser, serrated steel or plastic trowel or pneumatic spreader. Avoid contact with ferrous materials, which may cause bluish stains upon contact with the tannin of the wood. The curing time and bonding speed are influenced by temperature, humidity, porosity of the material and the amount of product used. The best results are obtained under the following conditions: optimum temperature of the product, surface and environment: 18-20°C; moisture in the wood: 8–12%. Residues of fresh product can be removed with water, hardened adhesive with paint thinner, acetone or painting cleaner. To improve moisture resistance, apply a double coating on solid wood
With hardener
- Production of laminate for under-sink cabinets
- Add 5% hardener to D3 PVA glue
- D4 catalysed PVA glue has a pot life of 6 hours (at + 20°C and 60% humidity). After 6 hours, the product irreversibly reverts to class D3
Open time:
6–8 minutes. This is the maximum amount of time that should pass between applying and setting at a temperature of 20°C (environment and wood), application of 150 g/m2, air humidity of 50%, wood humidity of 10%
This time is reduced if:
- Less than 150 g/m2 is applied
- The temperature is above 20°C
- Air humidity is lower than 50%
- Wood moisture is lower than 10%
- The gluing takes place in areas with air currents, especially hot air
It increases if:
- More than 150 g/m2 is applied
- The temperature is below 20°C
- Air humidity is above 50%
- Wood moisture is above 10%
Setting time:
- 20–30 minutes. This is the time that the item should be allowed to set, at a temperature of 20°C (environment and wood), application of 150 g/m2, air humidity of 50%, moisture content of the wood 10%
- It is advisable to wait at least 24 hours before further processing
This time is reduced if:
- Less than 150 g/m2 is applied
- The temperature is above 20°C
- Air humidity is lower than 50%
- Wood moisture is lower than 10%
It increases if:
- More than 150 g/m2 is applied
- The temperature is below 20°C
- Air humidity is above 50%
- Wood moisture is above 10%
Viscosity:
- Not to be confused with density, it is the product's resistance to flow
- 14,000 ± 1000 mPa, on average
- Do not dilute the product
