Handling
TACKMELT A9 must be heated at 150 -170°C with a suitable heating tool and kept at a set stable temperature during all the usage time (temperature changes cause a variation of the viscosity and, consequently, of the processing condition).
The best coating system is slot-die coating.
The product has been designed to resist to high temperature, but it is preferable to avoid thermal shocks.
Packing
TACKMELT A9 is supplied in 4 kg blocks packed in carton boxes or in drums..
Storing
Keep the product at temperatures between +5 and +35°C. Avoid contact with dust, liquids,...
