3M 3762 QLM hot melt adhesive specially for polystyrene and packaging

      What are the characteristics of 3M 3762 QLM?

The 3M 3762 QLM is a Low Melt adhesive from the Scotch-Weld range manufactured by 3M.

In contrast to the 3M 3762 Q reference, which is applied at approximately 210°C, this adhesive is applied at a lower temperature of around 130°C.

This significant temperature reduction allows for adhesion on heat-sensitive surfaces, such as expanded polystyrene.

      Applications

The formulation of 3M 3762 QLM provides great versatility, but it is primarily used in packaging applications (with heat-sensitive substrates) such as:

• Bonding corrugated cardboard.

• Creating displays.

• Cushioning expanded polystyrene in cartons.

      Product characteristics and customer benefits

The photo below demonstrates that a low melt hot melt adhesive does not degrade polystyrene, unlike a high-temperature hot melt that can cause damage due to its higher application temperature.

Applying at approximately 130°C offers safety to the user, significantly reducing the risk of burns. Additionally, there are fewer odors and fumes released during application.

Compared to 3M 3792 QLM, this adhesive has a shorter open time of 25 seconds and a lower viscosity, resulting in a more liquid adhesive.

It can be easily applied using an electric hot glue gun. Two compatible references include the 3M TC/TC-Q Applicator and 3M TC/TC-Q LT Applicator.

It is crucial to use this product in well-ventilated areas to prevent the accumulation of fumes released by the molten adhesive. The safety data sheet is available at www.quickfds.com.
