Metallic soaps and oleochemical additives serve as release agents. Stearates are mainly used as release agents for the subsequent moulding process. Zinc stearate, especially, has shown to perform very well due to its low moisture contentand low melting point.
LIGA ZINKSTEARAT 101 CG
This product is a precipitated stearate with a very low particle size. Its high primary fineness gives very good distribution in initial processing which leads to considerably improved release properties during the final moulding compared to the ’directly converted’ stearates. The dosage is approx. 1%.
LIGALUB ZINKSTEARAT 101/6
Produced by direct conversion, free-flowing zinc stearate with a low heavymetal content. This product has high colour stability.
LIGALUB SH
Release agent for the manufacture of SMC and BMC. Use of this product is beneficial for applications requiring subsequent treatment of the surface of the material. It has a very good release effect even at the high filler amount of some formulations.
LIGA CALCIUMSTEARAT 800
This free flowing stearate has proved itself as a very effective solution for difficult release problems. This is due amongst other properties to favourable melting point and melt viscosity of calcium stearate.
