CRA® 42
CRA® 42 is an extremely efficient controlled release additive for adjusting the release force of solvent-free DEHESIVE® systems.
Properties
- high release levels
- extremely stable release
- fast curing
Specific features of CRA® 42
- 可控型离型剂
- 无溶剂型
Data sheets
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.
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.
