POLYBOND EP
CHARACTERISTICS
► High bonding strength, ultimate bond strength is greater than cohesive strength of concrete
► Moisture tolerant, can be applied on slightly damp surfaces
► Non-shrinking
► High chemical resistance
► High durability
► Can be applied in both internal and external areas
DESCRIPTION : Polybond EP is an epoxy bonding agent and adhesive for the bonding of new concrete /render to old concrete. Polybond EP does not shrink and can be applied on slightly damp areas as well.
FIELDS OF APPLICATION
– bonding old to new concrete
– repair of concrete
– old and worn concrete
– glazed tile and bricks
– engineered and semi engineered bricks
– offshore and marine structures
APPLICATION INSTRUCTIONS
Surface preparation : All surfaces must be structurally sound and clean. Remove traces of oil, loose particles, laitance, demoulding agent, curing compound, grease, paint or bitumen. Smooth surfaces shall be abraded to get a mechanical key. If the concrete surface is not suitable or has disintegrated badly, chip off the degraded areas until a sound surface is obtained. New concrete should be cured until the shrinkage and moisture movement is the minimum.
Mixing : Pour part ‘B’ hardener to part ‘A’ resin pail and mix thoroughly to get a homogenous color and consistency. Application Polybond EP may be applied evenly with a short haired brush or with a trowel. Place the screed /concrete or repair mortar immediately after application of Polybond EP to avoid contamination. If the bonding agent dries out, apply a fresh coat.
COVERAGE 3-5 m2/L
CLEANING : All tools shall be cleaned with Polysolvent immediately after use. Hardened materials can be removed mechanically only.
STORAGE & SHELF LIFE : Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.
HEALTH & SAFETY : As with all construction chemical products, caution should always be exercised. Protective clothing such as gloves and goggles should be worn.
