- Application Details
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
- First pour in solvent-based DEHESIVE® polymer
- Add solvent and stir slowly until the mixture is homogeneous
- Add CRA® 23 release modifier and stir slowly until the mixture is homogeneous
- Thoroughly stir in Crosslinker to this mixture
- 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.
