Zero Rust:
Zero-Rust Application:

Mix well before using. Apply with spray, brush, or roller. Zero-Rust is a high solids product with 54% solids by volume. Airless, HVLP and conventional spray or brush and roll. Use 0.015-0.017 tip to apply with airless spray (smaller tip when spraying narrow or small parts). Remember, it takes 2-3 coats by brush and roll to equal one spray coat in dry film millage. For practical purposes, 2 mils of wet film yields one mil of dry film after solvent evaporation. If Zero Rust is thinned prior to application, additional wet film thickness must be applied to reach the same desired millage.

For best results apply a minimum of two coats, using a crisscross pattern from one coat to the next to help preclude holidays (pin holes) and thin spots. To assure adequate coverage, an easy visual barometer is to use two dissimilar colors for the first and second coats.

Do not apply too heavily and allow adequate time for flash off between coats (20 to 30 minutes is the minimum flash time between coats). This is important. Because Zero-Rust is designed for impermeability, the surface of the film starts closing as solvents start flashing off. This in turn retards the migration of solvents from the interior of the film. When a thick coat is applied or if adequate time is not allowed between coats, the paint takes much longer to dry thoroughly.

Topcoats:

Zero-Rust may be top coated with most generally available finish coat systems. As it is impossible to cover all topcoat combinations here, you will need to do test panels to determine compatibility and dry time window for your selected topcoat. High-solids, acetone-free, two-component automotive urethanes can be used successfully as topcoats. Urethanes containing acetone, however, make top coating air-dry finishes more difficult. As acetone is now Volatile Organic Compounds (VOC) exempt, it is increasingly being used in urethanes. Our testing shows that, because acetone is an aggressive paint stripper, it can soften and wrinkle or lift the undercoat, thus shortening the lift-free window. It requires more precise timing when top coating with low viscosity urethanes that contain acetone or that are thinned with acetone.

Health Safety Benefits of Zero-Rust Over Other Mil-Spec Primers:

The Zero-Rust rust protection system offers significant health safety benefits over all other high performance primers. Normally high performance in the coating industry indicates urethanes or epoxies which are known "body tissue reactive" materials and therefore cancer causing. The epichlorohydrins and isocyanates all react with water or OH groups present in all internal & external body tissues. Zero-Rust does not contain any of these components it is totally non-reactive to body tissues making applications safer, easier and less complicated. Application personnel can feel better about applying these materials knowing of their inherent safety to themselves and others.
