Silcolapse® 621

• Easy to use – as supplied or pre-diluted in water or in the medium to be defoamed
• Cost efficient, effective in doses as low as 10 ppm
• Highly effective in most aqueous media, and at many pH levels
• Chemically inert in foaming systems – will not alter the properties of the foaming medium
• Heat resistant – withstands temperatures up to 120°C (248°F)
• Low viscosity allows it to be used with automatic metering systems

Trial tests should be carried out to determine the quantity of antifoam needed to produce best results. Testing should be started at 10 ppm and increased or decreased based on the results. If prediluting product, do not use less than 1% solids and always dilute water into silicone. Infrequently, separation can occur during transport or storage; if this occurs, agitate gently until homogeneous.

When stored in the original, unopened container between (5-40°C), Silcolapse® 621 can be stored for 9 months from the date of manufacture.
