Instructions for use of the adhesive melt Henkel TECHNOMELT PW 839
- Recommended operating temperature on rollers — 170-190 °C
- 60-70 g/m2 when facing MDF and solid profiles
- 80-100 g/m2 when facing profiles from chipboard
Melt adhesives release volatile substances even within operating temperatures. The smell of vapors may cause irritation. Long-term temperature influence on the melt can cause partial decomposition of the glue. Therefore, it is necessary to take measures to ensure the removal of vapors from the working area, for example, by installing aspirating equipment.
