Polyurea/Polyurethane Coatings TRIZ Cases
- Polyester Resin Can Coating Retort Resistance
A polyester resin formulation with specific acid and glycol ratios forms a stable coating film for metal cans.
- Bio-based Polyurethane Coating for Controlled Release Fertilizer
Replacing petroleum MDI with bio-based 1,5-pentane diisocyanate improves biodegradability while maintaining mechanical strength.
- TDI Polyisocyanate Mixture for Low Viscosity High Solids Coatings
Blending polyisocyanurate with polyurethane resins lowers viscosity while maintaining high solids content, reducing solvent emissions in coatings.
- Fluorinated Resin Coating Cross-Linking with Aspartic Acid Ester
A fluorinated resin coating composition cross-links at moderate temperatures using aspartic acid ester and isocyanate.
- UV Curable Coating for Metallic Texture and Radar Permeability
Ultraviolet curable coating composition imparts metallic texture to vehicle components while allowing radar propagation for smart cruise control systems.
- Ambient-Curable Isocyanate-Free Polyurethane via Segmented Catalyst
Segmenting the acidic catalyst from pigments prevents adsorption, enabling immediate crosslinking without induction time.
- Polyurea Resin Flexibility Wear Resistance
Optimized polycarbonate diol carbonate content balances wear resistance against low-temperature flexibility in thermoplastic polyurethanes.
