Technical Guides
| Technical Guide | Summary |
|---|---|
| Absorpsi dibandingkan refleksi pada pelapis pengendali surya dan dampaknya terhadap akumulasi panas | Solar-control attenuation can come from absorption, reflection, or scattering. |
| Cure Temperature, Solvent Release, and Film Formation in NIR-Control Coatings | A usable cure profile lets solvent and air escape, allows the binder to level or coalesce, and develops the required network before settling, migration, skinning, bubbles, voids, or heat-driven material changes damage the coating. |
| Diagnosing Blue, Yellow, Brown, Gray, or Nonuniform Tint in NIR-Shielding Coatings | Tint is a symptom, not a unique material diagnosis. |
| How Coating Thickness and Particle Loading Control VLT, Haze, and NIR Rejection | Thickness and particle loading jointly set optical path and active material per area, but loading also changes particle spacing, dispersion, rheology, and defects, so VLT, haze, and NIR response require a two-variable film map rather than a single universal recipe. |
| How Phase Purity and Stoichiometry Change the Optical Response of NIR-Shielding Powders | Nominal formula does not fix an NIR powder's optical response. |
