Leakproof Varnish 706025

Overview

Leakproof Varnish 706025 is a two-component epoxy sealing varnish developed by Zodiac Aerospace for creating durable, leak-resistant protective coatings on aerospace components. Designed for brush application, the varnish provides an effective sealing barrier after full polymerisation and is intended for use under controlled environmental conditions. Its straightforward mixing ratio, extended working time and room-temperature curing make it suitable for aircraft manufacturing and maintenance operations requiring reliable sealing performance.

Application Guidelines

• Allow both components to acclimatise to room temperature before mixing.
• Stir the epoxy base thoroughly before adding the hardener.
• Add the hardener and mix until a completely homogeneous mixture is obtained.
• Allow the mixed product to stand for the recommended 1-hour induction period.
• Clean the substrate thoroughly, removing oil, grease and contaminants with methyl ethyl ketone (MEK) or an equivalent solvent.
• Apply one uniform coat using a paint brush.
• Allow approximately 24 hours for complete polymerisation at temperatures above 12°C.

Compatibility & Limitations
