Handling
TACKMELT A 45 must be heated at 150-170°C with a suitable heating device and kept at a set stable temperature during all the feeding 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 withstand high temperatures, but it is preferable to avoid thermal shocks.
Storing
Keep the product at temperatures between +5 and +35°C. Avoid contact with dust and liquids.
