TECHNOBOND D3
Water resistant wood adhesive
COMPOSITION:
Technobond D3 is is an aqueous polyvinil acetate dispersion based adhesive for
wood, containing reactive groups.
APPLICATION:
Technobond D3 is useful in the joinery industry as a waterproof adhesive. It
is suitable for
- indoor bonded joints (for long lasting or high moisture exposure),
- outdoor bonded joints,
in which one of the bonded joints is made of wood (for example: stairs,doors,windows).
It is also suitable for bonding tongue of board edges of laminate flooring and
hardwood floor.
Classification according to DIN EN 204- D3.

INSTRUCTION FOR USE:
The product has to be stirred up before using. It can be thinned with water(max.
10%), but it is practical to use it without thinning.Clean the equipment with
water before the glue dries.
Apply Technobond D3 using brush, spatula, roller, or machine roller.
To obtain an ideal adhesive strength, it is necessary to provide a clean, non-dusting,
tightly fitting surface. Do not use the adhesive, when the temperature of workplace,
adhesive and workpiece are below 5°C.
Usually it is enough to apply adhesive to one side(120-180 g/m2), but in the
case of strongly absorbing surface it is necessary to use it to both sides(60-100
g/m2/side). The ideal moisture content of the wood is 8-10%.
In the case of laminate flooring and hardwood floor apply the adhesive in the
tongue of board edges, and after prescribed pressing wipe the surplus from the
surface.
In the usual processing do not let open the adhesive coated surfaces more than
5 minutes, because of possible skin formation, which can be not suitable for
bonding.
To increase the adhesive strength jointed surfaces have to be pressed together
with 0,2-0,8 N/mm2 pressure.
The minimal required pressing time and temperature have to be optimized according
to the used technology.
We suggest the following as a guide to use this product:
Material 20 °C 50 °C 70 °C
Hardwood 17 min 9 min 6 min
Softwood 15 min 7 min 5 min
Laminated sheets 40 min 7 min 4 min
It is necesary 2 hours pressing to obtain the maximum strength.
Bonded joints reach the final strength after 24 hours drying.
The perfect watertightness is obtained after 7 days.
