Description
TACKMELT A 43 A is a hot-melt adhesive, based on thermoplastic elastomers (SIS) and synthetic resins.
Special synergistic antioxidants are added to ensure the best ageing resistance.
TACKMELT A 43 A has a very high tack and adhesion, with a good cohesion.
Application
The product can be coated at medium-low temperatures for the production of laminated products (foams, synthetic leather, wovens, ecc.) and labels.

Handling
TACKMELT A 43 A 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 conditions).
The best coating system is slot-die.
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 lower than +25°C. Avoid contact with dust and liquids. Keep far from heat sources and direct sunlight.
Use within 12 months from production date (unopened and in the original packaging).
