Corotech® Waterborne Bonding Primer is a one-component bonding primer that may also be used as a rust inhibitive universal primer. This product bonds to various metals creating a solid foundation for finishing coats. This product may be finish coated with a wide variety of coatings including alkyds, acrylics, epoxies, urethanes and moisture cured urethanes. Because of it’s versatility on all metals, Waterborne Bonding Primer will replace traditional wash coat primers and offers a safer to use alternative for all projects. This product is a high performance coating specifically designed for application directly to ferrous and non-ferrous metal substrates. It provides corrosion resistance as well as primary adhesion. It will tightly bond to Steel, Chrome, Brass, Copper, Aluminum, Galvanized Metal, Stainless Steel [when used on stainless steel or cold rolled steel, it is imperative that there be a surface profile of at least 1 mil and that it be jagged in nature]. It may be left uncoated for up to 3 months at 77°F prior to finish coating in interior applications. In exterior applications, if more than 2 weeks elapse, the primer film should be cleaned to remove any chalk that may have formed.

SURFACE PREPARATION: The performance of this product is directly dependent upon the degree of surface preparation employed. All dirt, fabrication and cutting oils and accumulated salts must be removed prior to employing specific surface preparation methods. Pressure washing with an oil and grease emulsifier or solvent washing in accordance with SSPC-SP 1 will best accomplish this task. This product is not designed as a direct-to-rust coating. All surface rust should be removed by hand tool cleaning (SSPC-SP 2), power tool cleaning (SSPC-SP 3) or by abrasive blasting.
- Galvanized Metal is iron or steel that is coated with a light layer of zinc. This process is done at a fabrication mill by dipping the prepared steel into molten zinc. Galvanized steel normally comes from the mill chemically treated or passivated, to prevent white rusting or oxidation of the galvanized surface during the time it is being stored or shipped to the job site. This leaves a surface that feels like it has a light coat of oil on it. It is very important that this type of surface be thoroughly cleaned using an oil and grease emulsifier or solvent washing in accordance with SSPC-SP 1.
- Stainless Steel normally comes from the fabrication shop with a very smooth surface. Due to the hardness of the stainless steel, it is very difficult to attain a surface profile for the paint to adhere to. It is our recommendation that any project using stainless steel have a few small test patches applied in different areas to ensure that there is proper adhesion of the primer prior to proceeding with the entire project.
APPLICATION: Mix the product thoroughly before application. The use of a drill mixer will best accomplish this task. Thinning is not recommended, however if necessary up to ½ pt of water per gallon may be used.Apply when temperatures are between 50°F (10 °C) and 90°F (32.2 °C) and with humidity levels less than 85%. Do not apply if air temperature is within 5 degrees of the dew point. One coat is sufficient to provide the proper bonding intermediate coat.
- Airless Spray (Preferred Method): Tip range between .013 and .017. Total fluid output pressure at tip should not exceed 2500 psi.
- Air Spray (Pressure Pot): DeVilbis MBC or JGA gun, with 704 or 765 air cap and Fluid Tip E.
- Brush: Synthetic Bristle only. Typical Brush application will apply 2 to 3 wet mils of product.
- Roller: Use a premium quality roller cover. Typical roller application will apply 2 to 3 mils of product.
