HYBRIDUR® 580

Hybridur 580 Polymer Dispersion is a product developed by Evonik Corporation. It belongs to a line of anionically stabilized urethane-acrylic hybrid polymers called Hybridur Polymer Dispersions. These hybrid polymers offer a combination of properties that include excellent wetting, adhesion, barrier, and film properties, making them suitable for various high-performance coating applications.

Here are some key points about Hybridur 580 Polymer Dispersion:

1. Composition: It is an anionically stabilized urethane-acrylic hybrid polymer dispersion.
2. Properties: It exhibits outstanding adhesion to a wide variety of substrates, including plastics, and offers fast dry times, typically less than 30 minutes touch-dry and 1 hour hard-dry.
3. Performance: It provides superior chemical resistance properties, resistance to stains, mild acids, and caustics. Additionally, it shows good UV stability and gloss retention for topcoats.
4. Applications: Hybridur 580 dispersion is used in air dry, baked, or crosslinked high-performance coatings on metal, wood, plastic, and previously painted substrates.
5. Formulation: It is easy to formulate and offers rapid dry times. The dispersion accepts pre-dispersed pigments and can be crosslinked with various crosslinkers.
6. Handling: It requires adequate coalescence to deliver maximum performance and should be adequately cleaned from processing and application equipment immediately after use.
7. Shelf Life: It has a shelf life of at least 24 months from the date of manufacture when stored properly.

Formulating dispersions of Hybridur 580 involves considerations such as film formation, wetting/spreading, foam control, viscosity control, gloss reduction, pigment dispersion, abrasion/mar resistance, UV resistance, and crosslinking.

The product is offered by Evonik Corporation for use in various coating applications, and starting point formulations are provided for clear coatings for interior and exterior wood applications.

Overall, Hybridur 580 Polymer Dispersion is a versatile material that combines the benefits of urethane and acrylic polymers, offering enhanced performance for high-quality coating formulations.
