With the rapid development of the electronic industry, people pay more attention to the stability of products, the weather resistance of electronic products have more stringent requirements, so now more and more electronic products need to be sealed, sealed electronic products can enhance its waterproof ability, seismic ability and heat dissipation performance, protect electronic products from the erosion of the natural environment to extend its service life.

The potting of electronic products will generally choose mechanical silicon material potting glue, because it has a good high and low temperature resistance, can withstand the cold and heat changes between -60℃ ~ 200℃ without cracking and maintain elasticity, the use of thermal conductive materials filled with modified and better thermal conductivity, potting can effectively improve the heat dissipation and moisture resistance of electronic components. In addition, silicone electronic potting glue is soft after curing, which is convenient for the maintenance of electronic equipment. Compared with epoxy resin electronic potting glue, the potting glue has high hardness after curing, easy to strain electronic components, poor resistance to cold and heat change, and prone to small cracks in the process of cold and heat change, affecting moisture resistance, and temperature resistance is only -10℃ ~ 120℃. Generally, it is only suitable for electronic equipment with no special requirements for the environment.

However, silicone potting adhesives also have two disadvantages:

1, the adhesion is poor, in order to improve the adhesion with the base material when used as a potting and coating material, it is usually necessary to undercoat the base material in advance or add tackifier, which is more troublesome to use.

2, easy poisoning (not curing), silicone potting glue is a relatively environmentally friendly potting glue, platinum curing agent is more active, easy to react with other impurities, causing poisoning. However, the more famous silicone potting glue manufacturers on the market have been very good at solving this problem, the anti-toxicity of the colloid is strong, can maintain stable curing ability, and also has a certain bonding ability.
