The WQE 500 Chemical Injection Anchor Bolt is a two-component epoxy bonding system. It is a product with structural characteristics that, when used in conjunction with a threaded bar or construction rebar, serves various situations of fastening in solid concrete, such as starters and consoles. It cures slowly and withstands very high loads, whether static or dynamic.
Applied with standard studs, threaded bars and rebars;
Fastening of high strength (structural) for static and dynamic loads;
Ideal for rebar pulls, recovery and structural reinforcement;
Excellent results in holes made with diamond drills;
Does not create tension in the concrete, which allows for smaller distances between fixings;
Styrene-free formula;
Uses specific Walsywa applicator for 400 ml;
The packaging can be reused by changing the mixing nozzle.
ASSEMBLY EXAMPLES
Structural reinforcements;
Structural recovery;
Fixation of metallic structures in general;
Fixation of machinery and equipment;
Fixing railings;
Fixing anchor bars;
Fixing of stairs, railings and gates.

NOTES
“Handling time” is the time in which it is possible to manipulate the product after mixing;
“Curing time” is the time when the resin “dries” completely and is able to receive loads;
Pullout tests must be done 24 hours after the final curing time;
After curing, keep at room temperature up to 40°C;
To know the ultimate tensile and shear load of threaded bars
IMPORTANT POINTS
Do not cut the mixing nozzle;
Clean the hole correctly as explained in the solid base application method;
At the time of application, the tube must have a temperature within the limits of 5°C to 25°C;
Do not apply the product to holes drilled in the ceiling. For this application, use the WQE 600, WQE 500 Plus, WQI 44, or WQI 44 Plus anchor bolts and follow the instructions;
