Use of release agent

Use of release agent

1. Classification by usage: internal release agent and external release agent;

2. Classification by service life: conventional release agent and semi permanent release agent;

3. Classification by form: solvent release agent, water release agent, solvent-free release agent, powder release agent, paste release agent 4. Classification by active substance:

① Silicon series mainly include siloxane compounds, silicone oil, silicone resin methyl branched silicone oil, methyl silicone oil, emulsified methyl silicone oil, hydrogenated methyl silicone oil, silicone grease, silicone resin, silicone rubber, silicone rubber toluene solution

② Wax series - plant, animal, synthetic paraffin, microcrystalline paraffin, polyethylene wax, etc.

③ Fluorine series: good isolation performance, low pollution to mould, but high cost of PTFE; fluorine resin powder; fluorine resin coating, etc

④ Surfactant series - metal soap (anionic), EO, Po derivative (non-ionic)

⑤ Inorganic powder series: talc, mica, clay, white clay, etc

⑥ Polyether series - the mixture of polyether and grease, with good heat resistance and chemical properties, are mostly used in some rubber industries with restrictions on silicone oil. The cost is higher than that of silicone oil series.

Other aqueous release agents with masking agent: use masking agent to fix water molecule durable release agent: silicone oil + silicone resin system, more than 800 times of multi-layer composite release agent: halogenated hydrocarbon film + polyethylene release agent + polyvinyl alcohol release agent aromatic polysulfone release agent mold treatment release agent containing halogenated polyether release agent: reduce vapor pressure, improve decomposition temperature, do not cause live contact with carbonyl Alkylsilane demoulding agent: internal demoulding, improving the adhesion to the surface of water-based ink reactive demoulding agent: after coating, chemical reaction is carried out to form a film. At the same time, adhesion to the surface of the mold is some representative demoulding agents, which have their own characteristics and can be used according to the use.

For example, it is used as the back treatment agent, stripping paper, anti adhesion agent (electric pole, telephone box, signboard, sign) of fiber adhesive tape, and anti pollution agent (interior and exterior wall coating, vehicle, barrier, road fence, etc.) to prevent the residual adhesion around the adhesive.
