InvoCor CI-3050

Calcium Borosilicate. ZINC FREE. InvoCor CI–3050 has been specifically designed as a high performance corrosion inhibiting pigment typically used in alkyd based protective coating systems and is highest borate content commercially available borosilicate corrosion inhibitor. In addition to excellent corrosion resistance, InvoCor CI-3050 also has a relatively low oil absorption, making it an excellent inhibitor choice in high solids alkyd formulations. Typical loading levels are usually between 1 – 5% by total formula weight. The following secondary benefits may be seen from InvoCor CI-3050:

  • May significantly improve the “lift resistance” of common medium and long oil alkyd primers when used at levels of 0.5 – 2.0%.
  • Aids in drying, both surface and trough dry, providing cost savings through the reduction of drier levels (especially cobalt). Surface dry may need to be balanced with the addition of zinc drier.
  • Provide flame retardancy through the mechanisms of released water of hydration and excellent char layer formation.

Zinc Phosphate Complexes

InvoCor CI-9010

Zinc Phosphosilicate. InvoCor CI–9010 is an excellent consideration as a zinc phosphate replacement. In many applications it demonstrates better corrosion protection than zinc phosphate on an equal weight substitution, while providing improved formulation economics.

This product has been specifically designed as a corrosion inhibiting pigment recommended for use in a variety of solvent and water-based chemistries such as: latexes, alkyds and epoxies. However, it is not recommended for use in acidic or high acid number resin systems. Typical loading levels are usually between 5 – 10% by total formula weight.

InvoCor CI-3305

Basic Zinc Phosphate: “Strontium and Silicate Free” analog of InvoCor CI-3365, demonstrating lowered low oil absorption, good resin versatility, and improved performance.

InvoCor CI-3305 can typically be used at 25% to 40% lower loading levels when compared to InvoCor CI-3365. It also is a choice to consider as a zinc phosphate alternative because its improved performance profile many times translates to improved formulation economics.
