A range of low shrink and low profile additives, named Norsolook, have been recently developed by Cray Valley for SMC, BMC, pultrusion and RTM applications.
The additives are intended to meet two market demands in the automotive sector. The first is for compounds having significantly improved paintability, either for on-line or off-line SMC parts. The second is for a better surface aspect for SMC Class A, since some OEMs still prefer to use metal as a high quality finish material. Cray Valley is working in partnership with major compounders, such as Menzolit and MCR, to address these issues.
To address the paintability issue, a combination of Norsolook additives has been developed that avoids popping when used with the new Norsodyne M01510 resin. In addition, Cray Valley says that lower VOC emission and lower solvent uptake is achieved and a conductive on-line formulation is also available. Norsolook A76086 is also now available to address the needs for better Class A finish.
