1.  dehydrating type one component silicone rubber

Dealcoholization type one component silicone rubber, because one component silicone rubber in the process of vulcanization to form elastomer release small molecules of alcohol (methanol/ethanol). At present, there are two kinds of single-component alcohol-type silicone rubber in the market: ethanol type and methanol type. Among them, the ethanol type is mainly used in industrial electronics industry, while the methanol type is widely used in construction and industrial electronics. Compared with acid and oxime-type silicone rubber, the biggest advantage is that the alcohol small molecules released by it have no corrosion, environmental protection and low odor, so that its application range is wider and it has become a mainstream product. Ethanol gum, releasing small molecule CH3CH2OH, commonly known as nanda gum, catalyzed by α silane system. Basic formula: 107 silicone rubber, α silane crosslinking agent, powder, silane coupling agent.

Advantages: table dry curing fast, slightly lower smell, simple process, no corrosion, because these advantages can improve the efficiency of production line application, so it is especially suitable for consumer electronics application industry, such as circuit board fixed, electronic components fixed, lamp plug fixed and other applications.

Disadvantages: yellow resistance, resistance to double 85 performance is poor, high volatile, so that its application in lighting, automotive electronics and other industries limited; Because its surface dry too fast (generally about 3-5min) limited, easy to yellowing, ethanol glue is difficult to be applied to the construction industry (too late leveling, dressing is crust).

Type of existence: flame retardant adhesive this type exists the most widely, is widely used in electronic components fixed; General adhesive small household appliances, electrical appliances bonding sealing waterproof; 704, etc. Thermal conductive adhesive process is simple: 107 can be directly used for ethanol thermal conductive adhesive preparation; Cellophane tape

2.  Didehydrating type RTV - 2 two component silicone rubber

Dealcoholization type two-component silicone rubber, usually refers to the need for A, B two components in A certain proportion of mixing, at room temperature by releasing alcohol small molecules (ethanol/propanol, etc.) and vulcanization into elastomer. Dehydrating two-component silicone rubber is widely used in construction, electronics and photovoltaic industries. According to the ratio, the state of the different, can be used for potting, can also be used for bonding sealing; Compared with the single component dealcoholization silicone rubber, it not only has the same heat resistance, weather resistance and other excellent properties, but also has the special advantages of fast deep vulcanization, long storage period, easy rework, so it is widely used.
