Low Viscosity Silicone Oils IOTA PDMS 47V3 -
47V10
Description: IOTA PDMS 47V3- 47V10 are a low viscosity
polydimethylsiloxanic fluids.
Applications:
IOTA
PDMS 47V3 - 47V10
47V3
for Chain Stopper for silicone polymerization;
47V10
for Lubricants (lubrication of elastomers or plastics on metal, on spandex
agent);
