APPLICATION / HANDLING
Apply using an applicator with rollers, spatula or brush. The amount of glue must be smeared according to the type of material used (generally between 50 and 150 g/m2). The working pressure of the press depends on the materials used, and ranges from 0.8 to 2 kg/cm2.
It is desirable to prepare the gluing mixture in non-metal containers or in stainless steel containers.

Before use in production, you must carry out your own tests and test all substrates before the gluing process.
