CRA 77 AMA
CRA 77 AMA is an extremely efficient two componet controlled release additive for adjusting the release force of solventless DEHESIVE® systems. CRA 77 AMA contains an additive to control misting in high speed coating processes.
stable release characteristics
anti misting properties
CRA 77 AMA can be processed together with nearly all solventless DEHESIVE® products. It is miscible with them in all proportions.
Mixtures of CRA 77 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 77 AMA , the product is ideal for the production of double-sided release.
The required amount of CRA 77 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 77 AMA 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.
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.
