Loctite Frekote S-50 is a mold release material designed to offer excellent slip and release properties and is highly recommended for silicone rubber molding applications. Once applied, the water based product will form a thin, thermally stable coating capable of releasing most silicone rubber molding applications. This advanced material needs no cure time at elevated temperatures and it is non-flammable. The mold release material reduces reject rates, has low mold buildup and offers very low VOC.
Frekote S-50 is a yellowish liquid and the odor is mild/sweet. Application temperature is between 220° and 390° Fahrenheit and it has the capability to dilute with water for a wide variety of ratios. The material needs to keep from freezing because it is not thaw stable and the properties of the material will be changed. Frekote S-50 should not be agitated prior to use. Pouring the liquid should be done slowly to prevent excessive foaming
Mold surfaces should be thoroughly cleaned and dried to prevent all traces of prior release agents and contaminates. This may be done by using Frekote PMC or other suitable solvents. Heavy buildup such as dry ice, dirt, sand, glass beading will require abrasion. Apply Loctite Frekote S-50 to molds that are preheated to a minimum of 220° Fahrenheit. Application should be done by using a finely atomized fan pattern. The gun output needs to be regulated to 2-3 FL oz. /minute for molds heated to 220-300° F. Two to three coats of full strength Frekote S-50 are recommend to condition the mold.
Care should be taken to avoid emulsion accumulation and run marks due to over application. Touch ups should only be applied to area where poor release is noticed. This will reduced the possibility of release agent or polymer buildup. When using this product, it is strongly recommended to read and understand the Loctite Frekote S-50 MSDS. Shelf life of the release agent when stored in its tightly sealed container is 12 months from the date of manufactured. The material should not be stored above 110° F and below 32° F.
