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.
Packaging
The product is supplied in 150g pillows packed in cardboard boxes (20 kg); fibre drums (180 kg).
Storing
Keep the product at temperatures between +5 and +35°C. Avoid contact with dust and liquids.
Use within 12 months from production date (unopened and in the original packaging).
Notes
The product, once coated, is subject to oxidation from air and light and must be protected in order not to compromise its performance.
