CRA^® 42

CRA^® 42 can be processed together with nearly all solvent-free DEHESIVE^® products. It is miscible with them in all proportions. Mixtures of CRA^® 42 and DEHESIVE^® are ideal for the production of release paper and PSA-laminates. Suitable substrates include glassine, clay-coated or PE-coated papers. Because of the high efficiency and stable release characteristics of CRA^® 42 the product is ideal for the production of double-sided release.

Processing

Batches of coating compound must be prepared in the
order given below.

1. First pour in CRA^® 42
2. Add DEHESIVE^® polymer in several portions and stir slowly until the mixture is homogeneous.
3. Thoroughly stir in Crosslinker to this mixture
4. Slowly stir in catalyst.

Local over-concentrations must be avoided.

Additional information

To obtain exceptionally high release forces, CRA^® 42 an also be processed without DEHESIVE^®. In this case, the amounts of catalyst and crosslinker required for efficient curing may vary from DEHESIVE^® containing formulations. However, we recommend the adjustment of specific formulations to optimize final coating properties for the intended use.
