- Product Highlights
- AT-8040 is a 1:1, meter-mix, methacrylate-based structural adhesive formulated to bond engineered thermoplastics, thermosets,composites, and metal structural elements in any combination.
- It has excellent adhesion to as-received metal surfaces, includingaluminum, galvanized, stainless and plated steels.
- It exceeds the strength of PVC, ABS, acrylic, polycarbonate, fiberglass andmany other composites and engineering plastics.
- It forms tough, high-strength bonds without surface preparation, primers, orchemical wipes.
- It features a 3-4 minute open time for fast fixturing.
- This product is formulated as a non-sag, high viscosity product with a special filler for holding anchoring studs and clips to walls and ceilings and is easily dispensed from cartridges withstatic mixer tubes. AT-8040 also provides low temperature impact and peel strength.
- This formulation is Reach Compliant and acid free.
- Substrate : Almost all substrates (except low energy & rubber)
- Non-slide General Purpose Bonder 30 ml cartridge
- Dispense Gun : AT-300
- Static Mix Tip : AT-850 3.25" Mix Tip
Applications & Uses
- Compatible Substrates & Surfaces
Properties
- Mechanical Properties
- Uncured Properties
- Typical Cured Properties
- Chemical Resistance
- AT-8040 exhibits good resistance to commonly encountered service environments and chemicals.
- Resistance to specific chemicals and environments must be tested by the end-user to ensure theadhesive is compatible to both the substrate and the environment.
