Dimer acid

Dimer acid is a type of dicarboxylic acid produced by dimerizing unsaturated fatty acids, typically derived from vegetable oils. It is widely used in the production of polyamides, adhesives, and coatings due to its unique chemical structure and properties.

**Properties**:
– High molecular weight and excellent thermal stability.
– Good flexibility, adhesion, and water resistance.

**Applications**:
1. **Adhesives and Sealants**: Used in hot-melt adhesives and pressure-sensitive adhesives.
2. **Coatings**: Provides flexibility and durability in paints and varnishes.
3. **Polyamides**: Acts as a building block for nylon resins and other polymers.

**Effects**:
– Enhances adhesion and durability in industrial applications.
– Improves flexibility and performance of coatings and polymers.
