Polyurethane has excellent bonding properties with other materials. This property is unfavorable in foam body molding. In the production of molded polyurethane foam, cast polyurethane elastomer and reaction injection molding (RIM) products, which are developing rapidly in the world. In order to quickly and smoothly remove the product from the mold, Release agent must be used. In polyurethane molding processing, release agents are used to obtain products with smooth surfaces.

Glass release agent, resistant to high temperatures up to 1200 ° C, with excellent lubrication performance, water-based, non-toxic, pollution-free, highly environmentally friendly, possessing superior film-forming adhesion, and does not react with molten metals (such as aluminum, copper, steel, etc.) or glass melt blades. It still maintains special effects of lubrication, release, oxidation resistance, and anti sticking at high temperatures.

Epoxy tree release agent, also known as epoxy resin release agent. It is designed for special molding and processing, and is an auxiliary agent used in the production of epoxy resin products. Different types of wax, resin, oil, silicone oil, and proprietary additives that can enhance, control, or maintain product functionality, stability, and service life. Its main function is to help epoxy tree products be removed from the mold and maintain their integrity and post-processing properties.

When various unsaturated polyesters are uncured, they are liquids ranging from low viscosity to high viscosity. After adding various additives and heating, they solidify and become rigid or elastic plastics, which can be transparent or opaque. The main use of unsaturated polyester is to make fiberglass reinforced plastic, which is one of the main varieties of reinforced plastics.

Concrete release agent refers to a substance applied to the construction formwork before pouring concrete, in order to prevent the formwork from sticking to the concrete surface, being difficult to remove, or affecting the smoothness of the concrete surface after pouring. Its main function is to form a film on the surface of the formwork and concrete to isolate them, hence it is also known as an isolation agent.

Casting release agent is a reagent composed of powder for demolding function, suspension agent, functional auxiliary agent, and solvent, used to reduce the friction force during demolding. Hot setting and cold hardening adhesives are widely used in casting production. After the sand mold (core) hardens, the mold is removed. In order to reduce the friction force during mold removal and ensure the quality of both the mold and core, casting release agents are brushed on the surface of the mold.
