Polyurea/Polyurethane Coatings TRIZ Cases

Resin beads reduce smudge contact, while silica-coated titanium oxide reflects sunlight to shield optical apparatus from heat.

Covalently bound polyorganosiloxane improves hydrophobicity while limiting blooming and leaching in anti-stain coatings.

Dark and clear objects gain diffuse NIR scattering for LiDAR visibility through nanoparticle coatings that limit visible haze.

Acrylic resin pairs and an isocyanate curing agent form a clear film that sands easily while resisting scratches during repair.

A tuned polyether amine range in the rheology agent helps paint films resist sag while reducing water blushing on vertical surfaces.

Multiple diisocyanates, acidic groups, and chain extenders help balance adhesion, chipping resistance, and finished appearance in aqueous coatings.

Low-molecular-weight polymers reduce VOC and raise solids but can weaken scratch resistance; TMCD polyester resins improve durability in 2K clearcoats.

Combining polycarbonate and polyester polyols helps urethane resins retain manufacturability while improving hydrolysis, heat, and weather resistance.

Branched carbon nanotubes replace chemical thixotropizers, preserving shear flow while improving conductivity and coating uniformity.

A branched polyether polyol mediates water and isocyanate reactions to extend pot life while retaining coating gloss.

A composite polyol blend and metal catalyst balance long pot life with low-temperature flexibility in a low-solvent polyurethane formulation.

Distillate monitoring adjusts carbonate feeding to stabilize hydroxyl values and simplify post-treatment during polycarbonate polyol synthesis.

This case examines biomass-derived levulinic acid ester oximes that block isocyanates while reducing toxicity and preserving deblocking reactivity.

Branched diol modification and secondary-amine blocking help prevent crystallization, improving blocked polyisocyanate storage stability.

Unmodified starch in aqueous resin dispersions creates soft-touch, ultra-matte films while retaining scratch resistance, transparency, and durability.

TMCD-based polyester polyols help 2K automotive clearcoats balance tree resin and scratch resistance while retaining gloss.

A cured primer containing polyisocyanate and hydroxy-containing (meth)acrylate strengthens bonding between the substrate and photochromic layer.

A dual-layer waterborne polyurethane coating replaces matting agents to reduce air pollution and surface friction in diving suits.

See how a polycarbonate diol and non-ionic emulsifier form a stable aqueous dispersion for soft-feel coatings with improved abrasion and chemical resistance.

Soft and hard segments help cured photochromic layers gain hardness while retaining fast reversible transformation kinetics.

A defined aromatic bismuth catalyst replaces toxic tin chemistry while supporting rapid polyurethane curing under low-bake conditions.

Polycyclic polyether polyol and non-aromatic polyisocyanate help toughen FRP gel coats while improving polyester-resin compatibility.

An organometallic catalyst helps hydroxy- and carboxy-functional resins crosslink with polycarbodiimide or polyoxazoline, limiting thermal damage.

Sequentially sprayed polyurea, elastomeric, and structural foam layers address brittleness while preserving fast, low-VOC composite manufacturing.

A malonic acid ester blocking agent keeps polyisocyanate stable in storage while enabling 80–85°C curing for harder, stronger coating films.
