Product Description:
An aliphatic polyisocyanate (HDI biuret) with ~75% solids in solvents, used as a curing agent for lightfast two-component polyurethane coatings. It delivers excellent gloss retention, outstanding chemical resistance, and long-lasting weather durability.
Properties
- Hardener: It serves as the reactive component that cures the polyurethane system.
- Chemical & Weather Resistance: Formulations using DESMODUR N 75 exhibit high resistance to chemicals and adverse weather conditions.
- Lightfastness: As an aliphatic polyisocyanate, it ensures the lightfastness of the coating, meaning it resists yellowing from UV exposure.
- Mechanical Properties: It contributes to outstanding mechanical strength and durability.
- Gloss Retention: Coatings cured with this hardener maintain their gloss for a long time.
Application
- Automotive and Industrial Finishing: Used in coatings for vehicles and industrial equipment.
- Wood & Furniture Coatings: Ideal for protective and decorative coatings for wood and furniture.
- Plastics: Applied in coatings for various plastic substrates.
- Corrosion Protection: Utilized in formulations designed to protect against corrosion.
- Light-Fast Coatings: Suitable for any application requiring light-stable and long-lasting performance.
