What should be noted when applying 3M adhesive to silicone gaskets?

Silicone pads are used in every industry as one of the main accessories for cushioning, shock absorption, and gear protection. Their application has occupied a certain market distribution demand and can be seen everywhere in our daily lives. They are not as good as foot mats, anti slip pads, protective silicone pads, and cushioning and shock absorption pads.

Many silicone adhesive pads are fixed by sticking double-sided tape to prevent detachment and sliding after too long. Therefore, under normal use, except for human conditions, 3M adhesive pads are unlikely to easily fall off because certain skills are also required in the backing process and processing. These experience skills can greatly improve the tightness of silicone adhesive pads. What are the specific methods for sticking gaskets?
The prerequisite for making high-quality gaskets is definitely to do corresponding preparation work. For example, the main products of silicone gaskets are designed to achieve adhesive backing effect, which naturally cannot achieve good results. Therefore, it is required that the face of the silicone gasket be clean, dry, free of impurities, oil stains and liquids, and the surface of the gasket should be clean and smooth, without potholes, etc.

There are usually two forms of silicone gasket backing, manual and fixture. Manual backing is mainly used for sampling and small batch trial production processing. It can be manually cut without a fixture die, and is not recommended for those with high requirements for edges and corners. Fixture dies are used for large-scale production processing. The premise of this method is that the silicone gasket processing manufacturer needs to prepare the mold opening method in advance, and the main method is self disassembly. After applying the backing adhesive, the edge can be removed by using a die. This processing technology has high precision and fast efficiency.

Pressure is a secondary issue, and the usual debonding phenomenon is likely due to the magnitude of pressure. To achieve a good backing effect, pressure needs to be applied to the 3M adhesive and bonding surface to ensure sufficient contact and bonding between the adhesive paper and the gasket. Manual pressure is usually not as good as a scraper, and a scraper is not as good as a pulley. Different pressure instruments are used for different liquid machines and silicone gaskets with different requirements.

The process of backing silicone gaskets is not complicated, and there are usually several reasons that can cause problems with the backing. In addition to the raw materials of the silicone gasket manufacturer and the 3M adhesive paper material, they are basically within the controllable range. Therefore, choosing a high-quality gasket supplier and materials is certainly important!
