Detailed Description
What Is Polyurethane Dispersions
Polyurethane dispersions are a type of polymer dispersion that is derived from polyurethane chemistry. They are typically produced by reacting a polyol with an isocyanate in the presence of a catalyst, resulting in a dispersion of polyurethane particles in a solvent.
Where To Use Polyurethane Dispersions
Polyurethane dispersions are widely used in various industrial applications, including coatings, adhesives, sealants, and elastomers. They are also used as binders in paint and coatings, and as a component in construction materials such as concrete and mortar.
Key Features Of Polyurethane Dispersions
- Excellent mechanical properties, including high tensile strength and impact resistance.
- Good chemical resistance to a wide range of solvents and chemicals.
- Flexible and can be formulated to have varying levels of hardness and flexibility.
- Can be easily formulated to meet specific requirements for color, texture, and other properties.
How To Use Polyurethane Dispersions
- For coating applications, apply the dispersion to a substrate using a suitable application method (e.g. roller, brush, spray).
- For adhesive and sealant applications, mix the dispersion with other ingredients as required (e.g. solvents, fillers) before applying it to the desired surface.
- For elastomer applications, mix the dispersion with other ingredients (e.g. resins, plasticizers) before casting or extruding into the desired form.
How Polyurethane Dispersions Is Manufactured
The manufacturing process for polyurethane dispersions typically involves the reaction of a polyol with an isocyanate in the presence of a catalyst, resulting in the formation of a dispersion of polyurethane particles in a solvent.
Technical Specification Of Polyurethane Dispersions
| Viscosity (cP) | 1200-1500 |
| Particle Sizes (?m) | 1-5 |
| Density (g/cm3) | 1.2-1.5 |
| Shelf Life (months) | 6-12 |
The technical specifications of polyurethane dispersions are critical in determining their performance and suitability for various applications. The viscosity, particle sizes, density, and shelf life of the dispersion all play important roles in its overall characteristics and behavior.
