At present, there are many uses of RTV silicone rubber, which can well realize the bonding and waterproof sealing of electronic products. RTV silicone glue now has two types: condensation type and addition type. The base glue of the addition type RTV silicone rubber glue is a linear polysiloxane with vinyl. After applying the glue using a three-axis automatic glue dispenser, a corresponding reaction is generated to form an elastic glue layer; while the condensation type RTV silicone rubber glue is a The reaction between silanol groups and active substances forms an elastic adhesive layer; whether it is an addition type or a condensation type RTV silicone glue, the purpose is to achieve waterproofing, sealing and bonding and fixing of electronic products.

So what are the characteristics of condensation type and addition type RTV silicone glue? The addition-type rtv silicone rubber glue has good hydrophobicity and heat resistance. Because of the active end group, it has good physical properties such as resistance to tension, elongation and tearing force, so that electronic products have certain shock-proof and shock-resistant performance. The condensed RTV silicone glue has good electrical insulation, moisture resistance and other properties, and almost no harmful substances are released during the curing process. It is an environmentally friendly glue. What are the use characteristics of RTV silicone rubber? No matter what type of rtv silicone rubber, it has good high and low temperature resistance, and it can also have good waterproof, sealing, insulating, bonding and other properties from a low temperature environment of minus 100 degrees Celsius to a high temperature environment of 350 degrees Celsius. Moreover, the RTV silicone glue is also resistant to radiation, oil and some organic solvents, which can protect the components from being affected by the external environment and work normally.
