APPLICATIONS

It is used for bonding of PVC edges. Specific for thin ones.

CHARACTERISTICS

FORM: granular

COLOUR: natural - walnut

VISCOSITY Brookfield at 200°C g27/5rpm: 10000 – 14000 mPa.s

SOFTENING TEMPERATURE (Ring and Ball): 79 - 83°C 

FOR BEST RESULTS

TEMPERATURE IN TANK: 130 - 140°C

TEMPERATURE ON ROLLER: 140 - 160°C

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°C – 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
