One. Organic silicone adhesive, as a common organic adhesive, has a series of significant advantages, but also has some disadvantages. The following is a detailed explanation of its advantages and disadvantages:
Advantage
1. Excellent weather resistance: After curing, the silicone adhesive has excellent resistance to heat, cold, and aging, and can maintain stable bonding effects under extreme temperature conditions.
2. Good electrical insulation: This adhesive has excellent electrical insulation performance and is suitable for applications with high electrical insulation requirements.
3. Excellent elasticity and flexibility: The cured silicone adhesive is an elastic silicone colloid with good flexibility and elasticity, capable of withstanding certain deformations without breaking.
4. Wide application range: Organic silicon adhesives have good adhesion to most metal and non-metal materials, and are suitable for bonding and sealing various materials.
5. Environmentally friendly: Many silicone adhesive products have passed environmental certification, are environmentally friendly, non flammable, do not release heat when burned, and almost no harmful substances are released.
disadvantages
1. Poor mechanical properties: Compared with some other adhesives, the mechanical properties of silicone adhesives are relatively weak and may not be suitable for situations that require significant mechanical stress.
2. Poor wear resistance: Its wear resistance is relatively poor and may gradually fail in long-term friction or wear environments.
3. Limited acid and alkali resistance: In strong acid or alkali environments, the bonding performance of silicone adhesives may be affected, leading to weakened or ineffective bonding effects.
In summary, organic silicon adhesives have excellent performance in weather resistance, electrical insulation, elasticity, and flexibility, but there are certain limitations in mechanical properties, wear resistance, and strong acid and alkali resistance.
Two. So, which silicone oil model should be used for adhesives?
1. Dimethyl silicone oil:
Characteristics: Dimethyl silicone oil is a colorless and transparent liquid with excellent heat resistance, cold resistance, and chemical stability.
Function: Penetrating it into the adhesive can effectively improve its weather resistance and water resistance, allowing the adhesive to maintain stable performance even in harsh environments. In addition, dimethyl silicone oil can also reduce the surface tension of the adhesive and enhance its adhesion to different materials.
2. Amino silicone oil:
Characteristics: Amino silicone oil is a type of silicone oil with amino functional groups, which has good lubricity and flexibility.
Function: Adding it to the adhesive can significantly improve its flexibility and tensile properties, allowing the adhesive to maintain good toughness under stress. Meanwhile, amino silicone oil can also improve the processing performance of adhesives and help reduce production costs.
3. Methyl hydrogen containing silicone oil:
Characteristics: Methyl hydrogen containing silicone oil is a type of silicone oil containing active hydrogen and has excellent crosslinking properties.
Function: Introducing methyl hydrogen containing silicone oil into the adhesive can improve the crosslinking density and strength of the adhesive through crosslinking reaction, making the adhesive have higher cohesion and adhesion. In addition, methyl hydrogen containing silicone oil can improve the heat resistance and chemical corrosion resistance of adhesives, which helps to extend their service life.
Among them, Dimethyl silicone oi Methyl hydrogen containing silicone oil from Jiujiang DeepSea Technology Development Co., Ltd. are your first choice!
