Description

Blackguard is a liquid rust converter and primer which chemically converts and passivates rust present on the surface to a black film which resists further corrosion. The vinyl acrylic copolymer employed exhibits very low permeability to water vapor and oxygen. Approved to MAF C23 classification.

CHEMICAL & PHYSICAL PROPERTIES

 Appearance: White Emulsion

 Specific Gravity: 1.24

 Flammability : Non Flammable

 Solubility in Water: Emulsifiable

APPLICATION

For use on rusted ferrous metals encountered in;  All types of road vehicles  Building steelwork  Bridge pylons  Cranes  Pipework  Shipping, etc.

METHOD OF USE

 Due to the variation of rust porosity an application of 10-12m2 per litre at an average film thickness of 75-100 micron per coat is envisaged.

 Ensure that the surface to be treated is free from soil and grease.

 Remove all heavy scale and loose rust, paint, dirt, etc. by wire brushing, chipping or either sand or water blasting.

 It is important to ensure that rust remains on the surface as it is necessary for the chemical action to proceed.

 Blackguard may be applied by spray, brush or roller.  Two coats are recommended for maximum conversion and protection.

 Blackguard may be applied to damp surfaces although protection from rain is necessary when the film is drying.  Blackguard is touch dry in twenty to thirty minutes.

 Allow twelve hours drying time between coats and twenty four to forty eight hours before applying top coats.

 Do not apply to surfaces where the temperatures are below 5°C or above 40°C.

 Always decant sufficient Blackguard into a separate plastic container for use.  Never pour unused material back into the original container as any rust present will continue to react with the chemical.

 Water based paints may stain if used over Blackguard.  Try a small area first and if staining occurs, allow to age and retest.

 Rinse equipment with water immediately after use.

 DO NOT use thinners.

DILUTION RATIO

 Use as is (100%).
