CRA® 45 AMA® is an exceptionally efficient controlled release additive specifically formulated for adjusting the release force in solvent-free DEHESIVE® systems. It offers high release levels, extremely stable release, and low levels of silicone mist at high coating speeds. CRA® 45 AMA® also demonstrates good bulk bath life, allowing for extended usability, as well as excellent thin-film bath life.

Application Details

CRA® 45 AMA® can be processed together with nearly all solvent-free DEHESIVE® products. It is miscible with them in all proportions. Mixtures of CRA® 45 AMA® 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® 45 AMA® 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® 45 AMA®
  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® 45 AMA® 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.
