Ressi EPO Aluminium Putty 90 is a two-component, solvent-free, aluminum-filled epoxy repair
compound designed for rebuilding, filling, and repairing aluminum and light metal surfaces. When
mixed, the base and hardener react to form a high-strength, lightweight compound.

It is a high-performance putty that provides excellent thermal conductivity, good corrosion resistance, and a natural aluminum appearance.
FEATURES & BENEFITS
Two-component, easy-to-mix and apply.
Can be applied on vertical surfaces due to its non-sagging properties.
Excellent adhesion to 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 aluminum castings, housings, panels, pipes, and structural components.
Filling cracks, holes, corrosion pits, and surface irregularities on aluminum equipment.
Maintenance and repair of marine vessels, automotive parts, aerospace components, and food processing equipment.
Suitable for workshops, transportation industries, marine environments, and applications requiring lightweight repairs.
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.
