Product Details

PERENOL E8 is a silicone-based defoaming and deaerating additive for solvent - based coatings. Here are the detailed information:

Chemical Composition

Modified siloxane (or a solution of modified silicon compounds).

Physical Properties

• Appearance: Colorless transparent liquid.
• Density: Approximately 0.85 - 0.88g/ml (at 20°C).
• Flash Point: 46°C.
• Refractive Index: 1.400 - 1.405 (at 20°C) (There are slight differences in data from different sources, and records of 1.408 - 1.412 also exist).

Product Features

• Good Versatility: As a general - purpose deaerator with good compatibility, it can be used in varnishes and topcoats. It can be applied to both transparent and opaque paints.
• Excellent for Thick Coatings: For thick - film solvent - based paints based on unsaturated polyesters, two - component epoxies, and polyurethanes, such as floor coatings, casting, and molding, it can ensure that the paint film surface is free of bubbles after curing when the film thickness exceeds 1mm.
• Applicable at Low Temperatures: Its defoaming effect is not affected when applied at low temperatures.

Application Fields

• Especially suitable for two - component epoxy, unsaturated polyester, polyurethane (PUR) systems, such as two - component epoxy and polyurethane solvent - based coating systems.
• It can also be used in medium and long oil alkyd resin systems, as well as related floor coatings, electronic potting compounds, and molding crafts.

Recommended Dosage

The addition amount is 0.2 - 1.0% of the total formula (the recommended addition amount ranges from different sources slightly overlap but are not completely the same). It can be added later, but it must be ensured to be dispersed evenly.
