From demolding to lubrication: How long-chain alkyl silicone oil becomes a multi-scenario solution

In the family of organic silicone functional materials, long-chain alkyl silicone oil is emerging as an upgraded option for downstream users to replace conventional silicone oil due to its "re-deposition, high-temperature resistance, and excellent lubrication" combined characteristics. It is also known as "dry silicone oil" or "non-oily silicone oil", attracting attention for its ability to undergo secondary processing on the surface after demolding without leaving oily residues. Its C8 to C30 long-chain alkyl groups and proportions can be customized as needed.

1. Dual breakthroughs in compatibility and hydrophobic/hydrophilic properties
After alkylating the silicone oxygen backbone of long-chain alkyl silicone oil, it not only retains the high-temperature stability and aging resistance of organic silicon, but also introduces the oil-loving and oil-repelling forces of long carbon chains. This structure enables it to be well-soluble with mineral oils, synthetic base oils, and cosmetic esters, while also having dual properties of hydrophobic and hydrophilic - after coating and forming a film, it repels moisture and can resist oil adhesion, providing a clean and refreshing surface effect for various substrates such as leather, metal, rubber, and plastics.

2. De-molding application says goodbye to "white fog" troubles
When used as a demolding agent, the low surface energy and moderate adhesion of long-chain alkyl silicone oil make the demolding clean, the surface of the product bright without white fog, and it has excellent re-deposition paintability. After demolding, there is no need for cumbersome cleaning to directly proceed with secondary processing such as painting and printing. This characteristic is significantly superior to traditional dimethyl silicone oil - the latter often leaves an oil-like film layer after demolding, restricting subsequent processes.

3. Superior lubrication and wear resistance performance compared to conventional silicone oil
In the lubrication scenario, as the carbon chain lengthens, the alkyl silicone oil molecules are more likely to entangle and form a thicker lubricating film, thereby enhancing lubrication and wear resistance, suitable for soft metals such as aluminum, zinc, and steel, as well as lubrication between rubber and plastic. When mixed with lubricating grease, it can improve the durability of the oil product and reduce mechanical friction loss, suitable for complex working conditions with wide temperature ranges and high loads, balancing long-term and stability.


4. Frequent customer questions and answers
Question: What is "dry silicone oil", and how is it different from ordinary silicone oil? 
Answer: "Dry type" means that after demolding, the surface is not sticky, can be repainted, and can be processed again. Ordinary dimethyl silicone oil often leaves an oily film after demolding and is difficult to reapply, while long-chain alkyl silicone oil forms a film that is refreshing and non-sticky, making it more suitable for subsequent coating processes.


Question: Can the length of the alkyl chain be customized? 
Answer: Yes. Long-chain alkyl groups can typically be customized between C8 and C30, and the proportion of the alkyl groups can also be adjusted as needed to achieve a balance between lubricity, compatibility, and hydrophobicity.


Question: Is it safe? Are there any toxicity concerns? 
Answer: Long-chain alkyl silicone oil has good thermal stability, is safe and non-toxic, and possesses properties such as resistance to high and low temperatures, anti-sticking, and aging resistance. It can be safely used in common scenarios such as rubber and plastic processing, metal processing, and personal care. However, extreme conditions beyond the limit of high-temperature decomposition should be avoided.
