The release agent needs to be diluted with water before use, and the dilution ratio and spraying time are both important. The dilution ratio of the release agent is too high, and the isolation film formed on the surface of the mold is very thin, making it difficult for the product to be demolded; The dilution ratio of the release agent is too low, which can easily cause the release agent to accumulate on the surface of the mold; The surface of the product is prone to spots and roughness. The spraying time of the release agent is recommended to be 4-8 seconds. Of course, this requires continuous accumulation of experience. For most rubber product customers, LongGreen 9346 release agent is a good choice.
These two are two things with different purposes, and cannot be said to replace or not replace. Using a water-based release agent is because the product shrinks less or the resin is prone to sticking to the mold. Generally, it is necessary to apply the mold to make your product easier to release. And gel coating resin is only used when there are surface requirements for your product, not for demolding, but for making your product surface harder and more glossy.
① Silicon series - mainly composed of siloxane compounds, silicone oil, silicone resin methyl branched silicone oil, emulsified methyl silicone oil, hydrogen containing 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 - has the best isolation performance, minimal mold pollution, but high cost of polytetrafluoroethylene; Fluorine resin powder; Fluorine resin coatings, etc. ④ Surfactant series - metal soap (anionic), EO, PO derivatives (non-ionic) ⑤ Inorganic powder series - talc, mica, clay, etc. ⑥ Polyether series - a mixture of polyether and grease, with good heat resistance and chemical properties, commonly used in certain rubber industries with limitations on silicone oil. The cost is higher than that of the silicone oil series. Zhebo Testing, in collaboration with Zhejiang University, can provide component testing and formula analysis for various fine chemicals such as release agents/cleaning agents/soldering fluxes/phosphating liquids/rubber/plastic additives.

Rubber release agent refers to a type of substance used to prevent adhesion between rubber products and the surface of molds, and to ensure smooth mold release without tearing. Spray or apply it to the surface of the mold cavity during use to form an effective isolation layer. The main requirements for release agents are: they have a certain degree of thermal stability and chemical inertness, and do not corrode the surface of the mold cavity; Residual decomposition products under the surface of the mold cavity; It does not affect the color of the product, but can give it a good appearance and is non-toxic; Easy to prepare and use. Shenyang LongGreen Science& Technology Co., Ltd produces various types of rubber release agents, mainly used in the field of rubber tires. Customers are welcome to inquire and order.
