Ressi Epo Zinc Putty 90

Ressi EPO Zinc Putty 90 is a two-component, solvent-free, high Zinc-filled epoxy repair compound designed for rebuilding, filling, and repairing galvanized and ferrous metal surfaces. When mixed, the base and hardener react to form a high-strength, sacrificial compound. It is a premium cold galvanizing repair putty that provides excellent cathodic (sacrificial) corrosion protection, strong adhesion, and a metallic zinc appearance. The cured material acts as an effective alternative to hot-dip galvanizing for damaged or worn zinc coatings.

FEATURES & BENEFITS

• Two-component, easy-to-mix and apply.
• 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 zinc castings, galvanized steel surfaces and equipment where a zinc-rich finish and cathodic corrosion protection are required.
• Rebuilding worn areas of machine parts and metal components.
• Filling cracks, holes, corrosion pits, and surface irregularities.
• Suitable for workshops, marine environments, electrical/thermal applications and process industries.

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).
