EPOXY BONDING AGENT
EP 300 is an un-pigmented two component, phenalkamine epoxy bonding agent. It is specifically designed for bonding new render or concrete to aged or old concrete substrates. It acts as a high strength bonding bridge between old and new concrete. EP 300 is a good bonding agent for tiles, bricks, concrete blocks, repairing potholes and spalled concrete etc.
• Excellent bond strength
• Forms a structural bond between new and old concrete
• Can be applied to damp surfaces
• Compatible with fresh cement or concrete products
• Excellent adhesion to most substrates

MIXING & APPLICATION
Individual contents of EP 300 should be thoroughly stirred before being mixed together. The entire content of the Part A should be poured into a larger mixing vessel to incorporate the Part B. Finally the part B is added to the same vessel. Mix all the two materials with spiral mixing paddle in a slow speed drill, continue until a consistant homogenous mix is achieved. One or more packs can be mixed simultaneously to ensure a quick rate of installation.
The mixed material should be applied to the prepared surface without delay using a brush. Only apply the Bonding Bridge to an area to which the new render or concrete can be placed while the bonding bridge remains tacky state. Immediately following application of the EP 300, place the new render or concrete and finish as required. Repeat the process until the full area to be treated is complete.
EP 300 should be applied whilst the surface temperature is between 10º - 35ºC. The product will cease to cure below 10ºC, but will recommence curing when the temperature rises above 10ºC. Curing time will also be adversely affected in situations where relative humidity is > 85%.Good ventilation should be provided during curing cycle.
EP 300 can be removed from tools and equipment by using CLI RTC 100 immediately after use. Any hardened material will need to be removed mechanically.

STORAGE AND SHELF LIFE
EP 300 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.
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.
