Ressi EPO Steel Putty 90 is a two-component, solvent-free, non-rusting Iron-filled epoxy repair com
pound designed for rebuilding, filling, and repairing worn or damaged metal surfaces. When mixed,
the base and hardener react chemically to form a high-strength, machinable compound that
adheres strongly to most metals and hard substrates.
It provides excellent mechanical strength, corrosion resistance, good heat conductance and
long-term durability under service conditions, making it ideal for emergency repairs and maintenance applications in industrial environments.

FEATURES & BENEFITS
Two-component, easy-to-mix and apply.
Excellent adhesion to copper and most rigid substrates.
Can be drilled, tapped, machined, or sanded after curing.
Resistant to oil, water, fuels, and many industrial chemicals.
Ideal for repairing worn parts, cracks, holes, and surface defects.
High compressive and tensile strength ensuring durable repairs.
RECOMMENDED USES
Repair of pumps, housings, shafts, flanges, valves, and other ferrous metal components.
Rebuilding worn areas of machine parts, castings, and steel structures.
Filling cracks, holes, corrosion pits and surface irregularities on iron and steel equipment.
Restoration and maintenance of heavy machinery, gearboxes, engine blocks, and industrial equipment.
Suitable for workshops, process industries, power plants and engineering applications.
SURFACE PREPARATION
All surfaces must be clean, dry, and free from oil, grease, rust, scale, and contaminants. For best adhesion, the substrate should be roughened by abrasive blasting or mechanical abrasion to achieve a minimum surface profile of 75 microns. After surface preparation, clean thoroughly with a suitable solvent cleaner to remove all dust and residues before applying the compound.
APPLICATION
Before use, thoroughly mix the Base and Hardener components in the ratio of 100:33 by weight until a uniform colour and smooth consistency are obtained. The mixed material should be applied immediately using a putty knife, spatula, or trowel.
The working time of the 100gm mixed material is approximately 90 minutes at 25°C, depending on ambient temperature. Machining, drilling, or overcoating may be carried out once the compound has fully cured, typically after 24 hours at 25°C. Clean all tools and application equipment promptly after use with a suitable epoxy thinner or solvent before the material hardens.
SHELF LIFE
12 months from date of manufacture (sealed containers).
