Lubricant light stabilizer
Thread Content
There is a type of lubricant that is initially a colorless, transparent liquid similar to water. After being placed under light at room temperature for 30 days, the color turned light yellow. It is likely that oxidation of unsaturated hydrocarbons has occurred. Does anyone know of a light stabilizer that, when added in small amounts, can prevent photo-oxidation of oils and thus extend their shelf life? At the same time, the cost cannot be too high. Those who know it, please give some advice. Thank you!
Try adding a small amount of propyl oxime or butyl oxime
What are the photo-stabilization mechanisms of propyl oxime and butyl oxime? I haven’t seen it in the documents.
Yes, for products such as rubber plasticizers and other oils that require good light and heat stability, a certain amount of light stabilizers and/or heat stabilizers are added to maintain their performance. It significantly improves the photothermal stability of oils! You can check CNKI for specific details; we are currently studying the photochemical and thermal stability of oil products. If you would like to discuss this further, feel free to contact me privately.
Specific light stabilizer formulations are required.
