CRA® 51 AMA®
CRA® 51 AMA® is an extremely efficient controlled release additive for adjusting the release force of solventless DEHESIVE® systems. CRA® 51 AMA® contains an additive to control misting in high speed coating processes.
- high efficiency
- rapid curing
- stable release characteristics
- anti misting properties
Spezifische Merkmale von CRA® 51 AMA®
CRA® 51 AMA® can be processed together with nearly all solventless DEHESIVE® products. It is miscible with them in all proportions.
Mixtures of CRA® 51 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® 51 AMA®, the product is ideal for the production of double-sided release.
The required amount of CRA® 51 AMA® is added to the particular DEHESIVE® product and the mixture is stirred until it is homogeneous. After addition of the crosslinker the catalyst is slowly added while stirring constantly. Avoid localized excess concentrations.
For more information on processing, please see our brochure entitled "Processing and Application", or the individual DEHESIVE® product data sheets.
To obtain exceptionally high release forces, CRA® 51 AMA® can also be processed without DEHESIVE®. In this case, the amounts of catalyst and crosslinker required for efficient curing may vary from DEHESIVECRA® 51 AMA® containing formulations. However, we recommend the adjustment of specific formulations to optimize final coating properties for the intended use.
