S666 is a water-based defoamer compatible with all types of paper impregnation resin system. It utilizes a biodegradable surfactants formula, free of wax and minerals.

S666 greatly prevents the formation of foams at a low dosage without any negative effects on the resin flow, distribution or film formation. S666 avoids surface defects, such as spotting, caused by foam due to the high resin viscosity, especially at lower room temperatures.

With S666, downtime for cleaning the machine due to excess foaming can be reduced.
