FEATURES

• Excellent bond strength
• High elastic modulus ensures effective transfer of stresses at bond interface
• Pre proportioned to give consistent performance
• Moisture-insensitive versatile in applications
• Resistant to a wide range of chemicals and liquids

SUBSTRATE PREPARATION

EP 325 treated surface must be hard, sound and free of dust and other barrier materials such as paint, lime coatings, plaster, curing agents, laitance, adhesive residues, etc., 2 - 3cm on either side of the crack that will inhibit adhesion to the substrate.

Use appropriate pneumatic drills for making suitable holes and fix the nipples or injection packers. Ensure the holes are free from debris and laitance before fixing the packers or nipples.

Use suitable adhesive for fixing surface port or nipples in position. The distance of ports or the nipples depends on the crack severity and the nature of the structure but with maximum centre-to-centre distance of 1000 mm. Close the whole length of crack opening using suitable adhesive.

MIXING

The individual component of EP 325 should be throughly stirred before being mixed together. The entire content of resin Part A should be poured into a large vessel so that the hardener Part B can be accommodated. Mix the two component throughly to ensure a smooth and consistent mix is achieved.

APPLICATION

The mixed EP 325 is injected / grouted into cracks / joints using the suitable equipment.

Use a high pressure, airless double diaphragm pump or two-component piston pump specially design for epoxy injection. Inject in each port or nipple (keeping all others closed except the next immediate one). When the resin start coming out of the next port / nipple, close it and continue injection / grouting until the pressure is maintained for 1 - 5 minutes.

Close the port, disconnect the pump and continue this process until all the ports / nipples are injected / grouted similarly.

After 24 hours remove all the nipples / ports and fill the resulting cavity with suitable epoxy adhesive.

LIMITATIONS

Once the mixed material has exceeded its pot life the viscosity and the characteristics of the product changes and any unused product should be discarded at this time.

CLEANING

Clean tools and equipment using CLI Eco Sol 205 immediately after use.

STORAGE AND SHELF LIFE

EP 325 has a shelf life of 12 months if kept in a dry, store between 5ºC and 30ºC in the original unopened containers. The product should be protected from frost, away from direct sunlight and sources of heat.

PRECAUTIONS

In case of contact with the eyes, rinse immediately with plenty of water and seek medical advice and after contact with the skin wash immediately with plenty of soap and water (do not use solvents). Prolonged contact with the skin should be avoided, especially where the user has an allergic reaction to epoxide materials. Always wear gloves and eye/face protection is necessary. Observe personal hygiene, particularly washing the hands after work has been completed or at any interruption whilst work is in progress. Care should be taken when removing gloves to avoid contaminating the insides. In case of accidents seek medical advice.

DISPOSAL / SPILLAGE

Spillage of any of the accelerating admixer product should be removed with plenty of water. Disposal of such product or empty packaging should be in accordance with local waste disposal authority regulations.
