At present, there are many uses of RTV silicone rubber, which can effectively achieve the bonding and waterproof sealing of electronic products. RTV silicone adhesive now has two main types: condensation type and addition type. The basic adhesive of the addition molding RTV silicone rubber adhesive is a linear polysiloxane with a vinyl group. After applying with a three-axis automatic dispensing machine, the corresponding reaction occurs and a elastic adhesive layer is formed; The condensed RTV silicone rubber adhesive is a reaction between silicone hydroxyl groups and active substances, forming an elastic adhesive layer; Whether it is additive or condensed RTV silicone adhesive, the purpose is to achieve waterproofing, sealing, and bonding fixation of electronic products.


So what are the characteristics of condensation type and addition type RTV silicone adhesive? The RTV silicone rubber adhesive with addition molding has good hydrophobicity and heat resistance. Due to its active end groups, it has good physical properties such as resistance to tension, elongation, and tear, making electronic products have certain seismic and seismic resistance. The condensed RTV organic silicone adhesive has good electrical insulation, moisture resistance, and other properties, and almost no harmful substances are released during the curing process, making it an environmentally friendly adhesive. What are the usage characteristics of RTV silicone rubber? Regardless of the type of RTV silicone rubber, it has excellent resistance to high and low temperatures, and can withstand temperatures ranging from -100 degrees Celsius to 350 degrees Celsius. It also has excellent waterproof, sealing, insulation, bonding, and other properties. Moreover, RTV organic silicone adhesive is also resistant to radiation, oil, and some organic solvents, thereby protecting components from the influence of the external environment and allowing them to function normally.
