TECHNOBOND FA EXPRESS
Indoor fast adhesive for wood
COMPOSITION:
Technobond Fa Express is an aqueous polyvinil acetate dispersion based
adhesive for wood.
APPLICATION:
Technobond Fa adhesive is suitable for producing internal woodworking products,
for bonding board joints, and for high frequency press. The film of Technobond
Fa Special is hard but it easy to polish. First of all we suggest it for sofwoods.
For other woods we suggest Technobond Fa Special, because it’s film is harder.
SAFETY ASPECTS:
Non-toxic and non-flammable
STORAGE:
Store in dry place protect from frost and direct sunlight. Optimal storage temperature:
+5-40°C. Shelf-life: 12 months, in original close container.

Adhesive strength(N/mm2): approx. 10
Classification according to DIN EN 204:D1- 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 Express 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.
Bonded joints reach the final strength after 24 hours drying.
The adhesive’s film is transparent after drying.
OUTSTANDING PARAMETER:
Fast bonding: min.3,3 N/mm2, after 2,5 minutes pressing time
min.4,5/mm2, after 5,0 minutes pressing time
Packaging: 5 kg and 32 kg plastic bucket; 130 kg and 150 kg barrel; 1000kg container
