GP-451 is a cationic type, water-based release agent containing 50% by weight of a modified dimethyl silicone fluid. GP-451 is recommended where a higher level of release performance such as multiple releases is required. GP-451 is a fine particle size emulsion compounded to provide exceptional stability both as a concentrate and at all dilution levels with hard or soft water. The use of cationic emulsifiers gives better active ingredient deposition on many surfaces that is obtainable with Nonionic or anionic emulsions.
