SEALBOND EPOXY UNDERWATER (385-UE) is a 100% Epoxy-Amine type curing agent especially formulated for use to cure at high humidity, low temperature (down to 5°C) and underwater. It has excellent chemical resistance and low water miscibility. It renders excellent adhesion and bonding capabilities designed for the all around remedy of structural concrete defects and flaws through pressurized injection and grouting and for other marine applications. It may be applied even on damp surfaces or even during cold conditions.

USES

• Bonding non-slip materials to hardened concrete.
• Pressure injection repairs of cracked concrete walls, floors, beams, and other structures for above or underwater applications.
• Forms an epoxy mortar when mixed with graded fine aggregates for high strength grouting repair of concrete surface/structures.

APPLICATION

PRESSURE INJECTION: Blow compressed air along the crack lines to completely clean, dry and remove dirt and other loose contaminating materials. Provide temporary seal on crack surface except entry and exit ports. Inject Sealbond 385-UE starting at the lowest entry port up to the proceeding ports until the voids are completely filled.

EPOXY GROUTING V-CUT SYSTEM: V-cut all cracks for repair. Blow compressed air along the crack lines to completely clean, dry and remove dirt and other loose contaminating materials. Apply by brush pure Sealbond Epoxy 385-UE to serve as primer then apply Sealbond Epoxy 385-UE mixed with silica sand or patching compound on v-cut surface.

EPOXY GROUTING ON CONCRETE HONEYCOMB: Chip off loose concrete. Remove dust, dirt and other loose contaminating materials. Install formworks on honeycomb providing for a small opening on the upper portion. Pour Sealbond Epoxy 385-UE mixed with silica sand. Remove formworks upon curing of epoxy grout.

MIXING AND CLEANING

MIXING: Mix thoroughly by volume 2 parts of resin to 1 part of hardener for 3 to 4 minutes. Any changes from the recommended proportion will affect its quality. Scrape the bottoms, sides and corners of the container to ensure complete and full blending. Prepare only enough quantities that can be used within the pot-life period. Do not delay application.

CLEAN-UP: Pressure injection tools and other equipment maybe cleaned with Sealbond Epoxy Reducer while the mixture has not yet hardened. Wash off hands with detergent and warm water.

CAUTION: Avoid contact with eyes and skin and avoid breathing its vapor. This product may cause severe skin irritation after prolonged or repeated exposure. Keep containers tightly closed and store in a cool dry place.
