AI Overview
Solvent-resistant PU (polyurethane) beads are high-performance crosslinked polyurethane particles designed for superior durability in paints, coatings, and inks. They act as matting agents, haptic modifiers (soft-touch), and functional fillers, offering excellent resistance to heat, scratches, and various solvents while maintaining flexibility and low oil absorption.
Key Characteristics and Benefits
- High Crosslinking: Their crosslinked structure provides high durability and resistance to solvent absorption and swelling.
- Surface Effects: They create low-gloss, matte finishes and provide a smooth, soft-touch or textured "suede" feel, particularly in automotive and industrial coatings.
- Dispersion: They are available as fine powders that disperse well in both solvent-based and water-based systems.
- Durability: They improve the overall abrasion and mar resistance of coatings.
Key Products/Manufacturers
- Decosphaera® (Lamberti Group): Spherical crosslinked polyurethane beads tailored for, coatings, offering consistent particle size (3µm to 50µm).
- iSuoChem® PU Beads APU20: Known for providing a soft suede matte finish, excellent heat/scratch resistance, and good dispersibility.
- Crosslinked Urethane Microparticles (NAGASE): Designed for high-end decorative coatings, offering, superior chemical resistance over traditional acrylic beads.
Chemical Resistance Profile
While resistant to many chemicals, standard polyurethane formulations can vary. Generally:
While resistant to many chemicals, standard polyurethane formulations can vary. Generally:
- Resistant to: Diesel oil, petroleum, gasoline, aliphatic hydrocarbons (e.g., isooctane), and mineral oils.
- Low Resistance to: Acetone, benzene, ethyl acetate, toluene, and other strong solvents, which may cause swelling.
Always check the specific TDS (Technical Data Sheet) for the exact solvent-resistance rating of the polyurethane beads in question.
