Best Practices for Dow Dowsil 20 Release Coating
After application, allow the mold surface to dry until completely free of diluent. Because the solvents used to dilute DOWSIL™ 20 Release Coating may be flammable, special care must be taken when applying the dilution to hot surfaces.
Easy to use
After dilution, DOWSIL™ 20 Release Coating can be applied by spraying, brushing, or wiping. Mold surfaces should be cleaned prior to application. Best parting characteristics are obtained when this product is applied in a very thin film.
Although not essential, a heat cure produces better release and increased durability of the parting film. Heating the molds for 5–10 minutes at 93–204°C (200–400°F) is suggested.
