At a glance for your formula

Omya Omyasphere 900 is a family of hollow glass microspheres used to lower formulation density. Supplier sources identify comfort paints, roof coatings and other construction formulations, with benefits from replacing heavier filler volume. Lower weight can improve yield and reduce transport demand, while thermal effects depend on the finished coating. A specific hollow-glass grade must be selected and tested for film thickness and shear survival.

Grade-specific screening values have not been recorded. Consult the selected supplier’s technical reference.

Omya: Omyasphere 900 series; paint-specific grade selection required

Omya · Supplier-reported · Awaiting human review

Listed claims

  • Lower coating density and transport mass
  • benefit depends on final application.

Suggested applications

  • Thermal comfort paints
  • Roof coatings
  • Adhesives and sealants
  • Polyester putties

Sustainability highlights

  • Lower finished-product weight can reduce transport demand.
  • Potential insulation and coverage benefits depend on the final formulation.

Performance highlights

  • Low-density hollow soda-lime borosilicate spheres.
  • Higher volume yield
  • grade-dependent compressive strength.

Grade scope & review questions

  • Supplier-reported information; awaiting human review. Applications are explicitly linked to 900-series bulletins. Solid Omyasphere 9W00 is excluded.
  • Gap: Selected 900-grade SDS/TDS: not established.
  • Gap: Starter-paint thermal/carbon savings and safe replacement volume require trials.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.
