Release agent is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make the object surface easy to separate, smooth and clean. Release agents are used in all kinds of molding operations such as glass fiber reinforced plastics, metal die-casting, polyurethane foam and elastomers, injection molded thermoplastics, vacuum foam sheets and extruded profiles. In molding, sometimes other plastic additives such as plasticizer will seep out to the interface, so a surface remover is needed to remove it.
There is also a plastic release agent, which is specially used for injection molding, blister and release between plastic products and molds in the production and processing process. Most of the sub products are sprays of iron cans. This kind of release agent is simple, light and easy to use. The following are the features of the introduction:
Structural formula or composition of release agent
High viscosity polysiloxane, surfactant, water
Release agent products
Plastic release agent, metal die-casting release agent, die-casting release agent, fluorine release agent, silica gel release agent, resin release agent, polyurethane release agent, concrete release agent, etc.
Performance characteristics of release agent
It does not affect the basic properties of the addition system.
Good diffusivity, permeability and water solubility.
Good heat resistance (300 ℃ high temperature).   stable chemical property and strong oxidation resistance.
No physiological activity, no corrosion, no toxicity, no adverse side effects, no combustion, no explosion, high safety.
Application of release agent
It is mainly used for demoulding and anti sticking of rubber, plastic, EVA, printing paste, wire and cable, hot melt adhesive products and adhesive tapes.
