CRA^® 23

CRA^® 23 can be processed together with nearly all solvent-based DEHESIVE^® products. It is miscible with them in all proportions.

Mixtures of CRA^® 23 and DEHESIVE^® are ideal for the production of release paper and PSA-laminates. Suitable substrates include PE-laminated paper, polyester films (PET) and papers.

Because of the high efficiency and stable release characteristics of CRA^® 23 , the product is ideal for the production of double-sided release liners.

Processing

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

1. First pour in solvent-based DEHESIVE^® polymer
2. Add solvent and stir slowly until the mixture is homogeneous
3. Add CRA^® 23 release modifier and stir slowly until the mixture is homogeneous
4. Thoroughly stir in Crosslinker to this mixture
5. Slowly stir in catalyst.
Local over-concentrations must be avoided.

Additional information

To obtain exceptionally high release forces, CRA^® 23 can 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.
