Mold sealers form micro-thin, thermally stable surfaces that are chemically bonded to the mold surface sealing micro porosity. Some of the new products result in multiple, contaminant-free releases and reduced manufacturing costs, can be either sprayed or wiped on the surface, maintain stability at temperatures of as much as 400°C, seals micro porosity and fills minor scratches on the mold surface resulting in a smooth, high gloss surface A few of the latest developments include Frekote mold sealers from Henkel are applicable in a variety of molding processes. When applied to a mold, Frekote sealers form micro-thin, thermally stable surfaces that are chemically bonded to the mold surface sealing micro porosity. Combined with Frekote release agents this results in multiple, contaminant-free releases and reduced manufacturing costs. The Loctite Frekote CS-122 reduces curing time to two hours resulting in a shorter waiting time before the user can apply the release agent. The new product also seals larger porosities better because it allows thicker coatings. Application is easier as the product can either be sprayed or wiped on the surface. The Loctite Frekote CS-122 can be applied at room temperature between 13°C and 40°C making the energy consuming heating of the mold unnecessary. Cured, the sealing remains stable at temperatures of as much as 400°C. Due to an improved formulation compared to its predecessor, the recently launched CS-122 emits less odor making its application more comfortable for users. This was designed to become the standard sealer for composites from low to medium gloss parts. It can be applied on both metal and epoxy molds and it is highly compatible with Frekote release agents. Gruber offers a variety of GruberCare™ Mold Sealers for a variety of composites and cast polymer molding applications. Benefits include efficient mold sealer and primer, easy application, enhanced mold gloss (see application details for appropriate coating technique), low odor, minimal mold build-up, versatility - can be used on all mold surfaces, durable - provides semi-permanent base-coat for mold release agent top coats. GruberCare MR Sealer is designed as a mold sealer for glass reinforced polyester, vinyl ester, epoxy or metal molds and for use in combination with the MR GP and MR HI-TEC products. It should be used to prevent styrene emission or migration from new molds and eliminate surface porosity of metallic molds. The resin both seals micro porosity and fills minor scratches on the mold surface. The result is a smooth, high gloss surface primed for GruberCare top-coat application. It is especially recommended for use on new molds and repaired areas on older molds. The product is recommended to seal micro-porosity in polyester or vinylester GRP molds. The product is also designed as a mold sealer for epoxy or metal molds. This is an advanced polymeric resin in an organic solvent blend. The resin both seals micro porosity and fills minor scratches on the mold surface. The result is a smooth, high gloss surface primed for GruberCare top-coat application. It is especially recommended for use on new molds and repaired areas on older molds. Key benefits include ease of application, enhanced mold gloss, minimal mold build-up, best bonding of top coats to mold surface, durable as it provides semi-permanent base-coat for mold release agent. This product finds application to fills porosity on porous molds, blocks reactive styrene in new molds, bonding of top coats to mold surface
