CRA 23

CRA 23 is an extremely efficient controlled release additive for adjusting the release force of solvent-based DEHESIVE® systems.



特性

  • high release levels
  • good release stability
  • excellent bath life

CRA 23的特殊性能

  • 可控型离型剂
  • 溶剂型

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.

储存

The 'Best use before end' date of each batch is shown on the product label.

Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
