1. Classified by usage: inner mold release agent, outer mold release agent;
2. Classification by life: conventional release agent, semi-permanent and long-term release agent;
3. Classified by form: solvent-based mold release agent, water-based mold release agent, solvent-free mold release agent, powder mold release agent, paste mold release agent
4. Classified by active substance:
①Silicon series-mainly silicone compounds, silicone oil, silicone resin methyl branched silicone oil, methyl silicone oil, emulsified methyl silicone oil, hydrogen containing methyl silicone oil, silicone grease, silicone resin, silicone rubber, silicone rubber toluene solution ,
②Wax series-plant, animal, synthetic paraffin; microcrystalline paraffin; polyethylene wax, etc.
③Fluorine series-good isolation performance, low mold pollution, but high cost PTFE; fluorine resin powder; fluorine resin coating, etc.
④Surfactant series-metal soap (anionic), EO, PO derivatives (non-ionic)
⑤Inorganic powder series-talc, mica, clay, white clay, etc.
⑥Polyether seriesa mixture of polyether and fat oil, which has good heat resistance and chemical resistance, and is mostly used in certain rubber industries that have restrictions on silicone oil. The cost is higher than the silicone oil series.
Other water-containing mold release agents containing masking agent: use masking agent to fix water molecules Durable mold release agent: silicone oil + silicone resin system, more than 800 times multilayer composite mold release agent: halogenated hydrocarbon film + polyethylene mold release agent + Polyvinyl alcohol mold release agent, aromatic polysulfone mold release agent, mold release agent for mold treatment, halogen-containing polyether mold release agent: reduce vapor pressure, increase decomposition temperature, and will not cause charged contact with carbonyl alkyl silane mold release agent: Internal mold release to improve the adhesion to the surface of water based ink. Reactive mold release agent: After coating, it chemically reacts to form a film and adheres to the mold surface. The above are some representative mold release agents, which have their own characteristics. And can be used separately according to the purpose.
For example, it is used as a back surface treatment agent for fiber adhesive tape, release paper, antisticking agent (telephone poles, telephone boxes, signs, signs), pollution prevention (internal and external wall coating, vehicles, roadblocks, road fences, etc.) Residual adhesion around the adhesive
