Introduction of 8831
HT 8831A /hardener HT 8831B has been developed for the laminating of transparent, aluminizing film and metalized films as well as aluminum foils for food packaging.
HT 8831 A/ hardener HT 8831 B is a product with low viscosity, good wettability.
Typical applicable structure is as follows+:
* Mass ratio changes from 100 :40 to 100 : 50 depending on the humidity and films.
Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 0.9–2.5 g/m² dry. For printed laminates the weight has to be adjusted accordingly.
The viscosity of HT 8831A / hardener HT 8831 B mixing at 45°C vs. time are shown in fig.1.
Fig.1 The Viscosity of HT 8831A/ Hardener HT 8831B vs. time at 45°C, 50-90% RH
Precise web tension control together with a suitable winding program avoids delaminations as well as telescoping and curling effects.
