Coating End Applications
  • Can be added at any manufacturing step.
  • Can be post-added.
  • In 2K systems: should be added in the resin part in most cases (to be checked with preliminary testing).
  • Indicative use dosages (% of total coating weight):
    • 0.1 to 0.3% on degreased substrates, not rusted, sand-blasted or not.
    • 0.3 to 1.0% on cast-iron or rusted substrates, on welds.
    • 0.3 to 1.5% for packaging protection.
  • Above dosages can be increased when the coating is applied in severe conditions of ambient humidity.
General Formulation Guidelines
  • Incorporation via pre- or post-addition possible
  • Efficient mixing required
  • Addition SIFLOC D below 80°C
  • Addition of key fabric softener ingredients at a temperature that is not below the melting point of the softener active. The dye, preservative and fragrance ingredients are typically added at the end at a lower temperature.
  • Typical incorporation levels:
    • 0.1 to 0.5% product as supplied in fabric rinse conditioners
    • 0.5 to 5.0% product as supplied in acidic cleaners

Technical Details & Test Data

Antiflash - Rust Performance

ASCOTRAN® H14 additives provide highest levels of flash-rust inhibition at low use dosages. It outperform high nitrite-containing additives or usual flash-rust inhibitors, even when film dries under severe humidity conditions.

  • Flash-rust comparative* test into a 1K Water-based Acrylic DTM Application on cold-rolled steel under normal drying conditions

ASCOTRAN® H14 - Antiflash - Rust Performance - 1

  • Flash-rust comparative* test into a 1K Water-based Acrylic DTM Application on sand-blasted cast-iron under severe drying conditions

ASCOTRAN® H14 - Antiflash - Rust Performance - 1

Note - * COMPETITORS 1, 2 and 3 are high nitrite-content additives.

Preserve Film Water Resistance

Whereas usual flash-rust inhibitors reduce coatings water-resistance, the ASCOTRAN® H14 technology combines excellent antiflash-rust performance with hydrophobic properties.

  • ASTM D870 (40°C) 250H, DFT 70 um, CRS
  • Dosage in Flash-Rust Inhibitor: 0.5%

Packaging Protection

Coatings can be highly corrosive and can cause, in most cases, corrosion of metallic cans which contain them. ASCOTRAN® flash-rust inhibitors also provide in-can protection.

ASCOTRAN® H14 - Packaging Protection - 1

Mechanism Liquid Dispersion Polymers (LDP)
  • A Liquid Dispersion Polymer is a dispersion of microparticles in a non-aqueous carrier phase and a non-ionic activating surfactant
  • Upon addition to water, the activating surfactant emulsifies the carrier phase and water swells the polymer particle by osmosis
  • The apparent viscosity depends on the amount of available water and the osmotic pressure
