The required amount of CRA® 17 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.
CRA® 17 can be processed together with nearly all solventless DEHESIVE® products. It is miscible with them in all proportions. Mixtures of CRA® 17 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® 17, the product is ideal for the production of double-sided release.
The 'Best use before end' date of each batch is shown on the product label.
