TECHNOBOND FA SPECIAL
Indoor fast adhesive especially for hardwood
COMPOSITION:
Technobond Fa Special is an aqueous polyvinil acetate dispersion based
adhesive for wood.
APPLICATION:
Technobond Fa Special is suitable for producing internal woodworking products,
for bonding board joints, and for high frequency press. Technobond Fa Special
is developed for hardwood, so it’s film is firm and hard. For other wood we
suggest Technobond Fa Express, because it’s film is softer.
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.
TECHNICAL INFORMATIONS:
Appearance: white, homogenous, thick liquid dispersion with characteristic
mild odour.
Viscosity:
(Brookfield ;7/10) 22 ± 8 Pas.
Solids: approx. 50 ± 1 %
Density: approx. 1,09 g/cm3
pH: approx. 5,0-6,0
Minimum gluing
temperature: 5 °C
Open time(at 20°C): 6 minutes
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 Special 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
