RTV (Room Temperature Vulcanizing) silicone adhesive is a silicone adhesive that cures at room temperature, which is widely used in various fields, such as electronics, automobiles, aerospace, etc. However, sometimes RTV silicone adhesives may not cure, which can lead to serious problems, such as affecting product quality and delaying production schedules. In the following, Baigao will introduce in detail the reasons that may cause RTV silicone adhesive not to cure, and provide solutions.
RTV silicone adhesive is usually a silicone adhesive that cures at room temperature, but if it does not cure, it may be caused by the following reasons:
1. Not completely mixed: RTV silicone adhesive is usually made of two parts mixed, that is, the base substance and the hardener. If the two parts are not completely mixed or mixed unevenly, it may result in incomplete curing.
2. Storage conditions: The curing of silicone glue is affected by storage conditions, such as temperature, humidity, etc. If the storage environment is not suitable, it may affect its curing effect.
3. Expired: Silicone glue has a certain expiration date, if it is not used beyond the expiration date, it may lead to incomplete curing.
4. Over-thick coating: If the coating is too thick, the oxidation rate inside the silicone glue will slow down, resulting in prolonged curing time or no curing.
5. There are oil stains or impurities: the surface of the silicone glue must be clean before curing, and any oil or impurities will affect its curing effect.
6. Insufficient hardener: insufficient hardening dose in silicone glue may lead to slow curing speed or incomplete curing.
Solution:
1. Make sure to mix the two parts of silicone glue well and follow the manufacturer's recommendations.
2. Choose appropriate storage conditions to ensure that the temperature and humidity are within the appropriate range.
3. Use fresh silicone glue and pay attention to check the production date.
4. Control the thickness of the coating to avoid over-thick coating.
5. Make sure the surface is clean before use, and remove oil and impurities.
6. Check the hardener content of silicone glue to ensure that the correct ratio is reached.
If the above methods still do not solve the problem, it is recommended to consult the manufacturer or professional for more professional advice and support.
