AT is a high-strength, acrylic-based adhesive anchoring system, formulated for use as a high-strength anchor-grouting material in a wide range of temperature conditions. It is a two-part system, with the resin and initiator being simultaneously dispensed and mixed through the mixing nozzle.
|Model No.||Option||Packaging Qty.||Carton Qty.||Compatible Tools|
|AT13||12.5 oz. side-by-side cartridge||1||10||ADT813S dispensing tool / AMN19Q mixing nozzle|
|AT30||30 oz. side-by-side cartridge||1||5||ADT30S, ADTA30CKT or ADTA30P dispensing tools / AMN19Q mixing nozzle|
Uncured material — Wipe up with cotton cloths. If desired scrub area with abrasive, water-based cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material — Chip or grind off surface.
Anchors installed with AT adhesive have been tested in accordance with ICC-ES Acceptance Criteria for Anchors in Unreinforced Masonry Elements (AC60).
