Handling

TACKMELT A 40 must be heated at 160-180°C with a suitable heating tool and kept at a set stable temperature while coating (temperature changes cause a variation of the viscosity and, consequently, of the processing condition).
The best coating system is slot-die.
The product is designed to resist to high temperatures, but it is preferable to avoid thermal shocks.

Packaging

The product is supplied in 150g pillows packed in cardboard boxes (20 kg); fibre drums (180 kg).

Storing

Keep the product at temperatures lower than +25°C. Avoid contact with dust and liquids.


Use within 12 months from production date (unopened and in the original packaging).
