Innovative low profile additives
A full range of low shrink and low profile additives, named Norsolook, have been recently
developed by Cray Valley to meet market expectations. These products may be used in
SMC, BMC, pultrusion and RTM applications.
A deep market analysis highlights two opportunities for new additives in the automotive
sector. The first opportunity is for compounds having significantly improved paintability, either
for on-line or off-line SMC parts. All players agree that paintability is the main issue, leading
to an increase in the final cost of the part.
The second opportunity 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 the leading compounders, like Menzolit and MCR, to solve this 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, lower VOC emission and lower solvent uptake is achieved and a conductive on-line
formulation is also available. A first industrial validation of this on-line formulation shows this
technology is of high added value for carmakers. On the other side, Norsolook A76086 is
now available to address the needs for better Class A finish.
Cray Valley is now leading the forefront of the technology for SMC Class A parts and is
committed to solve pending challenges of the automotive sector to lower the weight of cars,
to meet the new European challenging CO2 emission regulations.
