SPC-F2 (Gel)


Gel product

SPC-F2 is a water based acidic solution which will break up metal oxides and hydroxides formed on the surface of corroding ferrous metals. It will also remove stains from other substrates and clean rust fungus from masonry and stone. SPC-F2 reduces health and safety risks as it is non-flammable, non-toxic and biodegradable. Supplied in gel form the product can be applied to various surfaces. A sister product SPC-F1 is available in liquid form for dipping and washing applications.


SPC-F2 should be applied onto a dry surface where medium to light rust can be penetrated. SPC-F2 is more appropriate for removing heavy rust. Rust is the substance formed when iron compounds corrode in the presence of water and oxygen. When an iron compound comes into contact with a drop of water, an electrochemical process starts. On the surface of the metal, iron is oxidized to iron II oxide which is black in colour but what is more visible is the formation of iron III hydroxide which is red-brown.


SPC- F2 is designed to minimize health and environmental risks. It is non carcinogenic and contains no toxic elements. It also reduces the amount of hazardous waste generated. SPC- F2 is a water based product which is acid activated. Although containing very small amounts of acid, wearing protective gloves and goggles or face protection is recommended (for details, read the Safety Data Sheet)


Coverage – It is important to obtain an even coverage either by spray, brush or roller. A good build up of product is essential where 1 litre of product should cover 1m3 of surface. Concentrations of rust may require repeat applications.


Colour: Blue; pH – 2.5 to 3.0 Viscosity at 20°C: 9000 to 18000 cPs (gel) – Brookfields SG at 20°C – 1.00 ISO 2811 Flash Point: >100°C – ISO 3679


All surfaces including rubber and plastic should be taped or enclosed by polythene prior to application. On heavily rusted pieces power washing is recommended to remove loose scale. It is also important to wash and degrease the surface (SPC-801 General Purpose Solvent) as oily contaminants will inhibit SPC-F2 activity. For better results it is advised to cover the application area to reduce the effects of wind, rain or intense sunlight.


It is recommended that temperatures are above 5 to 10°C. The product works better at warmer temperatures. Good ventilation should be provided in confined areas.


When applying by SPRAY, BRUSH or ROLLER it is important to use a soft medium and apply generously to ensure an even and adequate coverage. SPC-F2 should be spread over the surface and allowed to thoroughly activate before removal. A general rule is that when the entire surface has turned black or dark green SPC-F2 has fully activated.


When using chemical removal products the first rule is not to remove them until they have been given time to work. It is therefore recommended that a minimum dwell time of 1 hour should be given. SPC-F2 will turn a dark green colour when activated. Patch tests are very important and must be carried out prior to application.


It is important to note that SPC-F2 contains no rust inhibitors. The surface will flash rust directly when rinsed with water. It is advised that the chosen paint system be applied as quickly as possible. Paint manufacturer’s guideline should be adhered to for required surface preparation. Some paints can be applied over damp or wet surfaces.


All containers are HDPE and can be punctured or split if not handled with appropriate care. Pails and drums must be secured during transportation to prevent damage. Lids, cap and closures must be tightened when products are being transported. SPC-F2 is produced from organic chemicals and is fully biodegradable. Neutralizing and dilution with water will be required to meet local waste or sewage disposal requirements. Spills should be contained and disposed under the same requirements.


Rust Remover SPC-F2 should be stored in a cool dry environment. Extended storage at temperatures exceeding 35°C is not advised and may reduce the products efficacy. All containers must be sealed properly when stored.


Avoid direct contact of the product with skin. Wear chemical splash goggles, rubber boots and gloves. Areas in direct contact with product including clothing should be washed thoroughly with water. Product may cause slight eye irritation and harmful if swallowed. Read label and MSDS before use.
