Polyurea/Polyurethane Coatings TRIZ Cases
- Flexible Granular Roof Coating for Asphalt Shingle Rejuvenation
Flexible granular coating restores asphalt shingles while preserving color and texture.
- Polyester-Polyurea Composition for Thin-Coating Adhesion and Wear Resistance
Controlled hydroxyl values and polyurea grafting deliver adhesion, abrasion, and chemical resistance at 2 mils or less.
- Hydroxyurethane Golf Ball Coatings for Moisture-Resistant Finishes
Cyclic carbonate and amine reactions form golf ball coatings with lower moisture sensitivity.
- Bio-Based Rosin Coalescent Coatings for Humid Film Formation
See how decarboxylated rosin acid helps acrylic and polyurethane coatings form continuous films with lower VOCs under humidity.
- Cardanol-Based Polyurethane Coatings for Controlled-Release Fertilizer
This case uses cardanol-based polyols in polyurethane coatings to improve nutrient release while reducing coating weight.
- Waterborne Sealer and Primer Compositions for Rapid Curing
Hydroxyl-functional core-shell particles and polyisocyanate crosslinking speed waterborne coating cure for sandability and smooth films.
- Two-Component Polyurethane Composition for High DOI and Low VOC
An emulsion polymer, alcohol alkoxylate, and polyisocyanate deliver high DOI and gloss with hardness and UV blister resistance.
- Polyurethane Curable Resin Composition for Low-Adhesion Heat Dissipation
This case uses polyester and polyether polyols to control adhesion while preserving 1.2–10 W/mK thermal conductivity.
- Water-Dispersible Polyurethane with Amide-Based Stabilization
Amide-based stabilization enables low-acid polyurethane dispersions with lower viscosity.
- Terminal-Amino Polycarbonate Polyol for Heat, Acid, and Water Resistance
Terminal amino groups improve heat, acid, and water resistance in polyurethane polyurea resins.
- Two-Component Polyaspartate Coatings for Self-Healing With Low Tack
Defined polyol ratios, Tg below 23°C, and storage modulus above 0.7 MPa balance self-healing with low tack.
- In-Mold Coating Compositions for Pinhole-Free Composite Surfaces
A mediator coating between mold release and prepreg improves surface finish while adding UV and solvent resistance during curing.
- Polycarbodiimide Compound for (Meth)Acryloyl Resin Water Resistance
Polymer side chains improve compatibility while carbodiimide groups protect (meth)acryloyl resins from water-induced deterioration.
- Thermoplastic Polyurethane Film for Thick, High-Strength Layers
High-solid polyurethane processing enables thick films with 50–80 MPa tensile strength.
- Two-Pack In-Mold Coating for Exterior Adhesion and Weatherability
A polyol-isocyanurate two-pack coating uses controlled light stabilization and low solvent content for durable in-mold exterior films.
- Dual-Curing Coating Composition for Water-Resistant Films
An aqueous carboxyl-polymer coating uses epoxy silane and isocyanate crosslinking to build a durable, water-resistant film.
- Thermoset Omniphobic Coatings with Functionalized Polymer Crosslinking
This coating process integrates an omniphobic polymer into a partially cured thermoset network for durable, clear water and oil repellency.
- Hybrid Polyurethane Composites for Complete Curing and Long Open Time
A hybrid polyurethane formulation uses polyol, acrylate monomers, and free-radical curing to improve completeness and HDT.
