At a glance for your formula

BYK-1740 is a vegetable-oil-derived defoamer for aqueous emulsion paints and plasters. BYK positions it as a replacement for mineral-oil-based defoamers, particularly in paints with pigment volume concentrations of 40–85. The supplier describes good storage stability and no adverse color-acceptance effects. Foam control, surface defects and long-term paint performance still require formulation testing.

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

BYK: BYK-1740

BYK · Supplier-reported · Awaiting human review

Listed claims

  • Vegetable-oil derivatives positioned to replace finite mineral oil.

Suggested applications

  • Emulsion paints, PVC 40–85
  • Emulsion plasters

Sustainability highlights

  • Renewable vegetable-oil derivatives replace finite mineral-oil resources.
  • Supplier lists low-VOC, APEO-free and PFAS-free attributes.

Performance highlights

  • Supplier describes effective defoaming and long-term stability.
  • Non-yellowing and no negative color-acceptance or odor effects are claimed.

Grade scope & review questions

  • Confirm the recommended pigment volume concentration and current regional SDS. Supplier ecolabel suitability is not finished-paint certification.
  • Gap: Current exact-grade regional SDS/TDS still required.
  • No exact chemical identity/CAS supplied for this commercial grade or family; do not infer one from chemistry words or trade name.

2 of 16 defined fields are recorded with a source. This measures structured information currently on this site, not the completeness of every linked PDF. Missing fields remain in the denominator.

Coverage is separate from scientific accuracy, human verification and EcoSafe assessment. Molecular fields may not apply to a grade or family; they are not filled from another material to increase its score.
