TECHNOBOND FA
Indoor wood adhesive
COMPOSITION:
Technobond Fa is an aqueous polyvinyl acetate dispersion based adhesive.
APPLICATION:
Technobond Fa adhesive is suitable for bonding internal woodworking products,
and for bonding board joints. It may be sanded prominently and protects the
sandpaper.

Classification according to DIN EN 204 : D2.
INSTRUCTION FOR USE:
The product has to be stirred up before using. The adhesive can be thinned with
water(max. 10%), but practical to use it without thinning.Clean the equipment
with water before the adhesive dries.
Apply Technobond Fa using brush, spatula, roller, or machine roller.
To obtain an ideal adhesive strength 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 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, the adhering 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 adhesive’s film is transparent after drying.
