DESCRIPTION
IES-251 is based on pure liquid epoxy polymers and aliphatic amine curing agents. Pigmentation is selected for hardness and durability in order to obtain the best possible properties in the cured film.

IES-251 is formulated with no solvents and is so completely tolerant of wet surfaces that it is an excellent anticorrosive coating for underwater application to steel, concrete and similar surfaces.

The cured film is hard, glossy and very tough. Application is easily made by brush, roller or plural component spray. Overcoating intervals are unlimited for ease of scheduling and maintenance.

USES
MARINE AND OFFSHORE Heavy duty maintenance for decks, tanks etc.
PETROCHEMICAL Anticorrosive for use under insulation or on sweating surfaces.
POWER GENERATION Ideal for draft tubes, penstocks, waterboxes and tubesheets.
FLOORING Exc. chemical and physical resistant flooring with or without abrasive.
SECONDARY CONTAINMENT Easy to apply, chemical and UV resistant lining.

SURFACE PREPARATION
NEW CONCRETE Surfaces should be left to cure for a minimum of 20 days before coating. Weak surface laitance must be removed by either acid etching or abrasive sweeping before coating.

EXISTING COATED CONCRETE Surfaces with worn but generally sound coatings should be prepared by vigorous scrubbing of the existing coatings with solvents or detergents to remove surface contamination. Make necessary repairs to the concrete surfaces with BIO-FILL or IES-251 and aggregate mixtures before applying the IES-251 protective coating. IES-251 will not soften existing coatings since it contains no solvents however the ultimate strength of the coating system will be determined by the strength of the existing coating residues. If the integrity of the existing coating is doubtful it should be removed to ensure good results from the IES-251.

METALLIC SUBSTRATES Surfaces are best prepared by air/abrasive blasting. Small areas may be cleaned using power grinders however this method is not practical for large jobs or for tight clearances.

APPLICATION
IES-251 is supplied in two gallon (7.6 litres) units. 1.33 gallons (5 litres) of epoxy base are filled into a two gallon plastic pail and 0.67 gallons (2.5 l) of curing agent are filled into a one gallon steel can to yield a 2/1 mixing ratio. Stir the curing agent into the base preferably using a mechanical mixer. Once mixing is complete, start application immediately - IES-251 does not require a "sweat-in" or induction time. Potlife is about 40 minutes at 80 degrees F (27 degrees C), small amounts of epoxy solvent may be added if the mixture begins to thicken noticeably towards the end of its working life. Apply IES-251 using brush, pad or roller in smaller areas or with a heated, plural component airless spray on larger jobs. Underwater application is best made using rollers or paint pads after surface preparation by air/abrasive or high pressure water blasting to remove loose surface contamination and marine biological fouling.

Applications may be made in one full coat at the required millage or may be made in multiple coats if necessary. Underwater applications are best made in one heavy coat to avoid the complications of biological settlement between coats. Above water it may be necessary to "stripe coat" edges to ensure adequate coverage.

TEMPERATURE
Temperature will exert a considerable influence on the rate of curing of chemically cured coatings such as IES-251 . In broad terms expect each 10 degrees C, (18 degrees F), rise or fall in temperature to half or double dry times and pot lives.

TRANSPORTATION
