half rust half protected

 

 

Remove Rust and Corrosion Inexpensively. Effectively Easily and Safely While Adding Corrosion Protection

Our rust removers, metal conditioners and paint strippers are biodegradable and non-polluting when compared to other industrial products—eliminating and/or reducing virtually all waste disposal problems. Corrosion is a persistent problem that must be carefully handled in a step-by-step process. Cortec’s environmentally friendly products make it easy to clean metal, remove rust, condition and prepare metal for temporary or permanent coatings and packaging. Cortec Surface Preparation products also add VCI corrosion protection.

Step Two - Remove Old Paint

Cortec VpCI®-432/433 Paint Strippers & Cleaners

Cortec®’s VpCI®-432/433 Paint Strippers and Cleaners are environmentally safe for removing paint from metal, wood and concrete, as well as providing protection against corrosion, flash rusting and discoloring of stainless steel, iron, copper, aluminum and brass.The heavy-duty formulation, which removes paint in three to thirty minutes, also effectively removes graffiti from concrete.These paint strippers, developed with maximum user safety in mind, do not contain many of the chemicals — such as methylene chloride, chlorinated solvents, methanol, toluene and acetone — found in other competing products. Cortec®’s VpCI®-432/433 Paint Strippers are formulated to remove urethanes and difficult-to-remove epoxies.They can handle the toughest coatings, yet are very safe compared to heavy-duty paint strippers. Works for removing Epoxy Coatings as well!


Step Three - This Is How You Get Rust Off Metal

Cortec® VpCI®-422 Liquid & VpCI-423® Gel Organic Rust Removers & Cleaners

Cortec’s VpCI®-422 and VpCI®-423 are non-polluting rust removal products which can be easily and safely applied to most metals.These products are based on a new chemical breakthrough to remove rust from metal and tarnish from steel, cast iron, copper, brass and chrome. Unlike other products currently available, these formulations are not based on hazardous acids, and when used correctly will not harm human skin or adversely affect most paints, plastics, wood, textiles, ceramics or rubber.

VpCI®-422 and VpCI®-423 are completely organic, 100% biodegradable and don't require special disposal for typical use. It is especially helpful for outdoor and marine applications where chemical waste disposal can be a problem. In rare situations, waste treatment may be required if a sufficient quantity of pollutants are introduced into the chemical solution. Both VpCI®-422 and VpCI®-423 are awarded with a USDA Certified Biobased Label.

CorrVerter® - Single component water based rust converter
corrverter


When removing rust may proove to be inconvenient, CorrVerter® is a fast drying, water-based one coat system (primer) rust converter that converts rusted surfaces to a hydrophobic passive layer and prevents further rusting thru the unique formulation of chelating agents and PVC resins. It provides long term corrosion protection by itself or by topcoating for extended performance.
Application: Substrate should be free of grease, oil, dirt, fingerprints, drawing compounds, rust inhibitors, or any other surface contamination that could affect adhesion. For production line applications, use VpCI®-440 or similar phosphatizing pre-treatment.

Cortec® VpCI®-440

Coating Adhesion Improver

VpCI®-440 is a water-based surface pretreatment for steel, iron, aluminum, brass, copper, zinc and other metals. VpCI®-440 can replace phosphatizing and chromating systems. VpCI®-440 will help coatings adhere better to hard to adhere to surfaces, such as increasing the adhesion of a powder coating to aluminum.

Dip the parts for 5 minutes in a tank of diluted VpCI®-440 and allow to dry. Once parts are dry to the touch, usually within 5-10 minutes, the parts can be handled and painted.
