The Advantages and Disadvantages of Organic Silicone Adhesives

Nov 19, 2021

Organic silicone adhesive is a one-component, semi-transparent paste-like room temperature curing adhesive, which is a high-performance elastomer that is naturally cured. It has excellent resistance to cold and heat, aging resistance and electrical insulation, and has good adhesion to most metal and non-metal materials.

advantage
1. Superior high and low temperature performance;
2. Low stress;
3. Good seismic performance;
4. Low compression set;
5. Superior electrical performance;
6. Excellent weather resistance, the outdoor service life can reach more than 20 years;
7. Low surface tension, excellent wetting performance;
8. Environmentally friendly, many products have passed the FDA's demonstration;
9. It is not flammable, does not emit heat during combustion, and almost no harmful substances are released [1].
shortcoming
1. Poor mechanical properties;
2. Poor wear resistance;
3. Poor resistance to strong acid and alkali;
4. Poor oil and solvent resistance;
5. High water permeability.

Organic silicone adhesive:According to the molecular structure, silicone adhesives can be divided into two categories: silicone resin adhesives and silicone rubber adhesives. According to the curing method, they can be divided into three categories: condensation type, addition molding, and polymerization type. Divided into three types: high temperature curing, low temperature curing and room temperature curing.

Features
It has excellent high and low temperature resistance, water resistance, corrosion resistance, and atmospheric aging resistance. It can be mixed and mixed with silicone resin solution or silicone rubber, fillers, crosslinking agents, catalysts and other additives. Suitable for bonding and sealing of metal, ceramic, glass and plastic parts.
use
Widely used in aerospace, aviation, electronics, construction, medical and health sectors
