G & W - G Mortar

 Elastomeric acrylic co-polymer and micro cements for concrete surface corrosion resistance repairing cement01 Product Description    G&W-G is a high quality polymer cement composedmicro cement and composites cements and liquid bindermade from elastomeric acrylic co-polymer. (It is an alkali material of a pH12)G&W-G is a especially made for concrete surface coating and repairing and protection material ofproblems in which is massive urban traffic volumes from the environment pollution such as chloride-induced corrosion, carbonation, freezing and thawing condition and etc.    02 Application    (1) Corrosion resistance and repair coating for concrete bridge and high level road pierand beam and girder(2) Most concrete building and civil structures exterior repair and anticorrosion coating.    03 Benefits/Characteristics     (1) Has elasticity, therefore inhibit of cracking by structural bearing(2) Alkali resistance property of the carbonated concrete(3) Carbonic gas and water percolation resistance property.(4) Very good adhesion with existing concrete structures(5) High durability and weather-ability     04 Test Results   Test Methods: ASTM C 1439, ASTM E 154, ASTM C 157, ASTM D 968, ASTM D 3730 Test Item Test Result Bond Strength( N / cm2 ) 3 days 7 days 14 days 197 213 254 Absorption Ratio( % ) 1 hours 5 hours 24 hours 0.15 0.2 0.2 Permeability Ratio ( % ) 0.25 Drying Shrinkage Ratio ( % ) 0.05 Coefficient of Thermal Permeability ( /?) 16.6 × 10-6 Abrasion Resistance Ratio ( % ) 0.4 Impact Resistance No Effect    05 Mixing Ratio    A B 1 kg 0.5 kg  06 Directions    (1) Job site surface must be free of oil, grease, laitance, debris and dust free.(2) Mix A compound 1kg and B binder 500g should be thoroughly mixed prior toapplication utilizing a power mixer capable of uniformly mixing the entire container.(3) Coating by brush, trowel and can use mortar power sprayer as circumstances require.(4) Pot life: up to 30 minutes (in normal temperature of 25 °C)    07 Caution    (1) When expecting rain, suspend operations.(2) When below 10°C, allow enough curing time (5~8hours)(3) When below 5°C, suspend operations. (4) In conditions of high humidity (over 90%) and thick fog, hardening is difficult.(Suspend operations when humidity is over 80%)(5) Mixing, use a scale for accurate measure, slowly mix A and B agent admixture using agitator. Do not mix for more than 3 minutes. This explanatory is intended solely as an application directive. It does not claim to be binding and valid for all modes of application. We recommend the carrying out of a preliminary test application relevant to full-scale application every time.     08 Storage    (1) Pails should be always tightly covered.(2) It should be kept in the normal temperature.(3) Dry cement should be kept in a moisture free area.(4) Liquid material should be kept in a over 1?, maybe do not use if frozen.
