Low temperature adhesive UNIBORD 636

Packaging
We only offer the whole package of 25 kg

Solid hot-melt adhesive with EVA base for application with manual edge-banding machines.

APPLICATIONS
It is used for gluing edges made of veneer, solid wood, plastic laminate, melamine-base materials, ABS and PVC. It is
characterized by long open time, quick setting speed and a good heat resistance of the glue joint.
With the addition of from 10 to 30% of this product to a product for straight a faster melting speed, longer open time and
better adhesion on difficult supports are obtained.

CHARACTERISTICS
FORM – granular
COLOUR  – natural walnut
VISCOSITY Brookfield at 200°C g27/5rpm: 10000 – 20000 mPa.s
SOFTENING TEMPERATURE (Ring and Ball) 85 – 90°C

FOR BEST RESULTS
TEMPERATURE IN TANK: 150 – 170°C
TEMPERATURE ON ROLLER: 160 – 190°C
IDEAL OPERATING SPEED: 8 – 15 m/min
HUMIDITY OF MATERIAL TO BE BONDED: 8 – 10 %
PRESSURE ON FILLETS: 3 – 5 kg/cm2

USAGE ADVICE
Frequently check the temperature of the glue on the rollers. Temperatures below the recommended value for
application cause a decrease in open time with consequent defective gluing results; at higher temperatures the
adhesive may decompose with the detriment of colour, viscosity and adhesiveness. When gluing cold or damp
surfaces, gluing defects may occur due to the reduction in open time.
In case of break of work, it is suggested to reduce of 30 – 40°C the temperature in tray to avoid a degradation of the
performance of the product.
Occasionally, unsatisfactory gluing results may be due to the type of edge or to the presence of release agents on the
materials/panels; a preliminary test is therefore recommended. Should such problem occur, it is advisable to use a
suitable preparatory product.

STORAGE
Shelf life: 24 months at 20°C in original closed packages.
