CRA® 42
CRA® 42 is an extremely efficient controlled release additive for adjusting the release force of solvent-free DEHESIVE® systems.
Eigenschaften
- high release levels
- extremely stable release
- fast curing
Spezifische Merkmale von CRA® 42
- lösemittelfrei
- Trennkraftregler
Datenblätter
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.
