Isophorone diisocyanate (IPDI) is an important organic chemical raw material, which is widely used in polyurethane, coatings, adhesives and other fields. The properties and uses of isophorone diisocyanate are described in detail in this paper.

1. Properties of Isophorone Diisocyanate

Isophorone diisocyanate is a colorless or slightly yellow transparent liquid with a strong pungent odor. It is a compound containing two isocyanate groups and is highly chemically reactive. The following are the main properties of isophorone diisocyanate:

1. Molecular formula: C13H10N2O2
2. Molecular weight: 226.24
3. Density: 1.21 g/cm
4. Boiling point: 245 ℃
5. Flash point: 135 ℃
6. Solubility: Soluble in organic solvents such as acetone, ether, benzene, etc, slightly soluble in water

2. Isophorone diisocyanate USES

1. Polyurethane industry
Isophorone diisocyanate is an important raw material in the polyurethane industry, which can be used to produce polyurethane foams, elastomers, coatings, adhesives, etc. In the field of polyurethane foam, isophorone diisocyanate reacts with other polyols to produce rigid or flexible foams with excellent heat and sound insulation properties. In the field of elastomers, isophorone diisocyanate can improve the tensile strength, tear strength and abrasion resistance of materials.

2. Coating Industry
Isophorone diisocyanate can be used to produce two-component polyurethane coatings. This kind of coating has excellent weather resistance, gloss retention, color retention and chemical resistance, and is widely used in construction, automobile, furniture and other fields.

3. Adhesive industry
isophorone diisocyanate can be used as a raw material for adhesives for the production of two-component polyurethane adhesives. This adhesive has high strength, weather resistance, water resistance and heat resistance, and can be used for bonding in wood processing, construction, automobile and other industries.

4. Other fields
In addition to the above fields, isophorone diisocyanate can also be used to produce polyurea, elastic fiber, sealant and other materials.

In conclusion, isophorone diisocyanate as an important chemical raw material has been widely used in polyurethane, coatings, adhesives and other fields. Understanding the properties and uses of isophorone diisocyanate will help to better understand its application in chemical production.
