Handling
TACKMELT 46C must be heated at 150-170°C with a suitable heating equipment 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 has been designed to withstand high temperatures. We advise to avoid thermal shocks.
