 HITEK supplies two products for the removal of graffiti from metal, wood, concrete, and plastic surfaces. These highly effective but environmentally friendly products.

VpCI432/433  - Graffiti Remover Heavy-duty liquid removes, inks and paints from metal, wood and concrete. This low odor cleaner is non-flammable and free of methylene chloride and ketones.

The above photos are of a garage door that was cleaned of graffiti. Typical removal times are in the region of 3 to 30 minutes depending on the type of paint and surface.

The surface should be cleaned thoroughly of dirt and grease prior to graffiti removal with one of the CORTEC water-based cleaners such as VpCI 416.

Then apply the 432 or 433 with a brush or spray on the surface to be cleaned. Monitor the softening of the paint, then remove the material by washing or wiping

Finish off with final rinse of VpCI 416

Corrosion Recovery Metals

 
HITEK supplies products and techniques for the recovery of metals when they have corroded in storage or use. These products in keeping with CORTEC’s policy of producing environmentally friendly solutions for corrosion control mean that they are some of the most effective and safe products on the market today. The fact that the VpCI technology is effective on multiple metals means you only have to buy one range of product to fulfil your metal recovery needs.

Examples of such products are:
VCI 422  - VpCI enhanced skin safe water based rust removers. The mild but effective rust removers come with the added benefit of the CORTEC vapour phase corrosion inhibitor technology. It is also effective at removing the tarnish from other metals such as copper, brass, chrome and aluminium.

VCI 423  - Gel version of VCI 422

VCI 416  - An extremely effective alkaline cleaner/degreaser that is water diluteable and normally used for temporary corrosion protection and cleaning for metal parts. When diluted with 4 parts water to 1 part VCI 416 the corrosion protect lasts for up to 6 weeks indoors on bare metal parts.

VCI 415  - Aircraft approved cleaner/degreaser to Mil-PRF-87937C, and several ASTM D specs similar to VCI 416.

CorrVerter  - A water based rust converter for poorly prepared metal surfaces. Makes an extremely good primer for metals.

Corrwipe 500  - Removes light rust and tarnish from tools and parts leaving a very thin film of protective VpCI on the surface providing temporary protection for up to 6 weeks. The wipe and film has antistatic properties and therefore can be used to clean electronic circuits and components. The patented CORTEC corrosion Inhibitors are effective on most metals. The wipe is skin safe.

VpCI 609  - A water-soluble ferrous metal protection powder that can be used as an additive in wet blasting applications giving immediate protection to the blasted surface. Protecting it temporarily prior to further treatment or painting.

VCI 432/433  - Liquid paint remover with added VpCI technology from CORTEC. VCI 433 is the gel version of 432
