Corrostain™ 228 features a unique pigment chemistry which combines the dual functionality of Corrosion Inhibition and Tannin Stain Inhibition. This dual functionality aids in the reduction of raw material inventories and also provides effective inhibitor formulations. It is designed to provide good stability and performance in both solvent and water based systems. Typical use level is between 2 – 6% based upon total formula weight.

Wayncor™ 240 - Corrosion Inhibitor Pigment is a white Basic Zinc Molybdate anti-corrosive pigment which imparts good corrosion resistance to protective primers. It has a wide variety use in thermo set and thermo plastic systems. It can be used alone or in conjunction with other anti-corrosive additives. The typical use level for this product is between 3 – 7% based on total formula weight. It has a small particle size and narrow distribution which will permit it to be used in wash primers, DTM, or primer applications.

Wayncor™ 240 - Corrosion Inhibitor Pigment

WPC Technologies Strontium Chromate 177, with the chemical formula of SrCr04, is a low dust and very low oil absorption corrosion inhibitor pigment. It is recommended for high solids primer formulations. It is characterized by a unique high apparent bulk density and is widely used in aerospace primers for aluminum protection.

WPC Technologies Strontium Chromate 177

Hybricor™ 204S - Hybrid Corrosion Inhibitor Pigment is a pigment grade Hybrid corrosion inhibitor, effective in primer applications intended for cast and structural aluminum protection. It can easily be incorporated into the coating using a high speed disperser. Hybricor™ 204S has a particle size of 7 Hegman which permits its use in both primer and DTM applications.

Hybricor™ 204S - Hybrid Corrosion Inhibitor Pigment

Wayncor™ 205 - Corrosion Inhibitive Pigment is an anti corrosion pigment that utilizes a calcium ion exchange mechanism to inhibit the corrosion process. Its near neutral pH allows it to be used in a wide variety of formulas without a negative impact on paint stability. The fine Hegman grind (6.5 minimum) permits its use in thin film applications (4 – 10 microns) such as coil coatings and in more traditional industrial applications where the dry film thickness is higher. This fine Hegman value also allows the product to be high speed dispersed. The Wayncor™ 205 mechanism works well on both ferrous and non-ferrous substrates. Wayncor™ 205 can be used as the sole corrosion inhibitor or synergistically with other inhibitive technologies.

Wayncor™ 205 - Corrosion Inhibitive Pigment

Wayncor™ 214 - Calcium Borosilicate is an effective corrosion inhibitive pigment designed for alkyds and other solvent based systems. Typical use level is 3 – 7% total formula weight.

Wayncor™ 214 - Calcium Borosilicate

Wayncor™ 211 is an anti-corrosion inhibitive pigment that is very effective in solvent and water based epoxy primers. It does not affect the pot life of 2K systems. It can also be used alone or as a synergist with Zinc Phosphate. Typical use level is between 3 – 7 % total formula weight.

Wayncor™ 211

Wayncor™ 213 - Corrosion Inhibitive Pigment is a general purpose corrosion inhibitive pigment which demonstrates good stability and corrosion resistance in a wide variety of systems. Typical use level is between 3 – 7% total formula weight.

Wayncor™ 213 - Corrosion Inhibitive Pigment

Wayncor™ 226 - Corrosion Inhibitive Pigment is a premium multi-component corrosion inhibitor pigment that comprises distinctly different inhibitive species to provide a high degree of corrosion protection on ferrous substrates. Although versatile it is highly recommended for water based acrylic primers where a high degree of corrosion resistance is required. Typical use level is between 3 – 7% total formula weight.

Wayncor™ 226 - Corrosion Inhibitive Pigment

Corrosperse™ 177 MA is a 75% dispersion of Strontium Chromate in MAK and Acetone. It has a Fineness of Grind (7 Hegman) which means no grinding is required and it can easily be incorporated using high speed mixing techniques. Because the product is a pourable liquid, there are none of the concerns associated with Hexavalent Chrome in pigment form, specifically exposure to dust.
