The Crack-Pac contains a two-part, low viscosity 100% epoxy solids crack injection formula. The resin is contained in the cartridge and the hardener is contained in the nozzle. Once mixed, the adhesive has the viscosity of a light oil and a low surface tension which allows it to penetrate fine to medium width cracks (Suggested width range: 0.4 - 6mm).

Features:

• Chemically bonds with the concrete to restore strength: not just a crack filler.
• Seals cracks: protects flooring and rebar in the concrete from moisture and corrosion.
• Simple in-the-cartridge mixing: No worries about mixing ratios or extra tools.
• Totally portable: no external power source or expensive equipment needed.
• All accessories are disposable: no equipment to clean.
• Components are separate until mixed: longer shelf life with no barrier leakage.
• Non-shrink material resistant to oils, salts and mild chemicals.
• Meets the requirements of ASTM C-881, Type I & II, Grade 1, Classes B&C.

Installation:

• Cartridge Preparation and Mixing Instructions
• Epoxy-Tie Injection Guide

Application:

Epoxy-Tie injection epoxies are suitable for repairing non-moving cracks in concrete walls, floors, slabs, columns and beams. They can be used to inject cracks in damp or wet conditions with excellent results (water cannot be seeping from the crack during injection or cure). Apply to concrete 5°C or above. For best results, warm epoxy to 15°C or above prior to application.

Shelf Life: 2 years in unopened cartridge.

Storage Conditions: For best results, store between 7° - 32°C.

colour: Resin- blue; Hardener- clear amber. When properly mixed the adhesive will be a clear amber colour. During cure the material turns a blue colour. After approximately two weeks it turns back to clear amber.

Clean Up:

Removal of cured adhesive - Chip or grind off surface. Uncured Adhesive - Wipe up with cotton cloths. If desired, scrub area with abrasive, waterbased cleaner and fl ush with water. If approved, solvents such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling fl ammable solvents. Solvents may damage surface to which they are applied.

Chemical Resistance:

Very good to excellent against distilled water, inorganic acids and alkalis. Fair to good against organic acids and alkalis, and many organic solvents. Poor against ketones.

Technical Specifications:

Meets the requirements of ASTM C-881 Type I & II, Grade 1, Classes B & C.
