Ac100-ProVinylester Injection Adhesive Anchoring System

ProdUcT descriPTion

The AC100-Pro is a two-component vinylester adhesive anchoring system. The system includes injection adhesive in plastic cartridges, mixing nozzles, dispensing tools and hole cleaning equipment. The AC100-Pro is a versatile anchoring system designed for various applications and base materials. it is also very suitable for bonding rebar to concrete as post-installed reinforcement application.

GenerAL APPLicATions And Uses

FeATUres And BeneFiTs

•  designed for use with reinforcement bars of internationally common grades

•  Consistent performance in uncracked and cracked concrete

•  flexible anchorage lengths of up to 2000 mm

•  simple installation

•  versatile low odor formula with quick curing time

•  Applicable for wide range of ambient temperatures

•  Cartridge design allows multiple uses using extra mixing nozzles

2.) Blow the hole clean using a hand pump or compressed air 4 times minimum.

3.) Brush the hole with the proper wire brush 4 times minimum.

4.) Blow the hole clean using a hand pump or compressed air 4 times minimum.

5.) Fill the hole up to approximately 2/3 with adhesive.

6.) Push the rebar into the hole while turning slightly.

7.) Allow the adhesive to cure for the time specified for the actual concrete temperature prior to applying any load.

• The following information is meant to give the designer aid in the preliminary design process. No responsibility is taken for the correctness of the data.

• Reinforcement bars installed by AC100-PRO adhesive proved as good as cast-in reinforcement bars. For this reason their design complies with the concrete design approach which basically determines the anchorage length required to transfer a given design load from the reinforcement bar into the concrete.

• For further details and background information please see the introduction of this manual and to the respective design codes.
