Silicone resin occupies an important position in the field of sealing adhesives due to its unique properties. The silicon-oxygen bond (Si-O) in its molecular structure gives the material many excellent properties, making it an ideal choice for sealing adhesives.
Silicone resin sealing adhesives have excellent high and low temperature resistance, can maintain elasticity and stability for a long time in the temperature range of - 60℃ to 200℃, can withstand extreme temperature changes, and are not prone to sealing failure due to thermal expansion and contraction. It performs well in high-temperature environments such as aerospace and automobile engines, as well as in the sealing of outdoor facilities in cold areas. It has strong weather resistance, good UV resistance and aging resistance, can be exposed to the natural environment for a long time, prevent aging and cracking due to climate influence, and ensure long-lasting sealing effect. It is often used for sealing of building exterior walls, roofs and other parts.
In addition, the adhesive also has good waterproof and moisture resistance, can effectively block moisture intrusion, and prevent the sealed object from being eroded by moisture. It is suitable for sealing bathrooms, kitchens and underwater facilities. It has excellent electrical insulation and can be used for sealing electronic and electrical products. While ensuring sealing, it provides reliable insulation protection to prevent leakage and short circuit.
When using, mix the silicone resin with the curing agent, filler, etc. in a certain proportion, stir evenly, and then apply or fill it to the part that needs to be sealed. During the curing process, the silanol group undergoes a condensation reaction to form a cross-linked three-dimensional network structure, which allows the adhesive to cure and play a sealing role. According to different application scenarios and needs, the performance of the sealing adhesive can be customized by adjusting the formula, such as improving bonding strength and flexibility.
