CRA® eco 42

CRA® eco 42 is an extremely efficient controlled release additive for adjusting the release force of solvent-free DEHESIVE® systems. It is based on renewable raw materials according to “Standard REDcert²”.



Properties

  • high release levels
  • extremely stable release
  • fast curing

Specific features of CRA® eco 42

  • Controlled Release Additive
  • Solvent-free

CRA® eco 42 can be processed together with nearly all solvent-free DEHESIVE® products. It is miscible with them in all proportions. Mixtures of CRA® eco 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® eco 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® eco 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® eco 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.

Storage

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.
