CRA 17 is an extremely efficient controlled release additive for adjusting the release force of solventless DEHESIVE® systems. CRA 17 can be used to obtain the highest release values of all CRA® modifiers.
- high efficiency
- rapid curing
- stable release characteristics
Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from WACKER subsidiaries or may be downloaded via WACKER web site http://www.wacker.com.
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.
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.
