Cashew Nut Phenol Technical Overview
Cashew nut phenol, derived from the shell liquid of cashew nuts (Anacardium occidentale), is a naturally sourced phenolic compound with applications in resins, coatings, and friction materials. Below are its key properties and uses.
1. General Properties of Cashew Nut Phenol
| Property | Description |
|---|---|
| Chemical Name | Cardanol (primary component) |
| Source | Cashew nut shell liquid (CNSL) |
| Appearance | Dark brown viscous liquid |
| Solubility | Soluble in organic solvents (alcohols, ethers) |
| Density (g/cm³) | 0.92–0.98 |
| Viscosity (25°C, cP) | 500–1.500 |
| Flash Point (°C) | 200–250 |
| Main Components | Cardanol, cardol, anacardic acid |
2. Key Applications and Performance
| Application | Function & Benefits |
|---|---|
| Phenolic Resins | Improves flexibility and water resistance |
| Coatings & Paints | Enhances adhesion and chemical resistance |
| Friction Materials | Used in brake linings for heat stability |
| Surfactants | Acts as a bio-based emulsifier |
| Epoxy Modifiers | Increases toughness and impact resistance |
3. Advantages vs. Limitations
| Advantages | Limitations |
|---|---|
| ✔ Renewable & sustainable source | ✖ Dark color limits use in light coatings |
| ✔ High thermal stability | ✖ Requires purification for some applications |
| ✔ Good chemical resistance | ✖ Variable composition based on extraction method |
Cashew nut phenol is valued for its versatility in industrial applications, particularly where bio-based alternatives to petroleum-derived phenolics are preferred.
