Product Details

The Weld Mount AT-300 Dispensing Gun is designed for use with the following adhesives (sold separately): AT-2010 (mix tip AT-850), AT-4020 (mix tip AT-650), AT-6030 (mix tip AT-650), and AT-8040 (mix tip AT-850). The AT-300 hand-operated gun used with the appropriate mixing tips provide precise mixing and dispensing of the adhesives. The mixing tip is easily replaced after the adhesive cures. We recommend (5) mixing tips per adhesive cartridge. Mixing tips (or nozzles) are sold separately.

Each gun is supplied with a one-to-one (1:1) ratio adhesive plunger. (For AT-2010 and AT-4020 adhesives only.)

The AT-13 adhesive plunger has a ten-to-one (10:1) ratio and is used only with the AT-6030 adhesive (sold separately).

Guns are available individually and in (10) packs. Also available is the AT-13 adhesive plunger, sold individually.

Info & Guides

Description of the WELD MOUNT ADHESIVES

AT-1030 Is A specially formulated acrylic adhesive which cures in 12 minutes and has working strength within 40 minutes. AT-1030 is packaged in a 30 ML side by side dispenser cartridge with a built in plunger. Cut off the tips and dispense the amount needed for hand mixing. A cap is included to deal the cartridge for reuse. AT-1030 is a good general purpose bonder for all substrates except low energy plastics and rubber. AT-1030 has a shelf life of 12 months when stored at 72 degrees or less. The cartridge will bond 50-75 parts.

AT-2010 is also a two-part acrylic adhesive, which is formulated with high viscosity to allow instant bonding of Weld Mount System fasteners to any surface (horizontal, vertical or overhead). AT-2010 is packaged in a two part 50 ML cartridge which is mounted in the AT-300 adhesive dispensing gun using a 1 to 1 plunger. A special mixing tip is used to mix the two components thoroughly before use. AT-2010 sets in approximately 6 minutes, develops working strength in 15-20 minutes and dries to a light yellow color. AT-2010 is used typically for bonding Weld Mount parts in lighter duty applications.

AT-4020 acrylic adhesive will bond to fiberglass, steel, aluminum, glass, wood and many other substrates. However, it should be noted that AT-4020 adhesive will not bond well to StarBoard, low energy plastics or rubber. AT-4020 does not adhere as well to metals as it does to composite substrates. Weld Mount AT-4020 Acrylic Adhesive is a specially formulated to hold studs and standoffs without sagging. The Acrylic Adhesive cures in 10 minutes and has a working strength within 30 minutes at 72 Degrees F. The 50 ML cartridge will bond approximately 100-150 parts. AT-4020 is used primarily for bonding Weld Mount parts to composites in heavier duty applications.

AT-6030 adhesive is a two-component, 10:1 mix ratio structural adhesive with outstanding adhesion for bonding metals, carbon fiber, composites and most plastics. Most metals can be bonded without priming. This advanced product is designed to meet specific requirements of the transportation industry, including reduced read through on show surfaces. The combination of minimum surface preparation, primerless metal bonding and low read through makes AT-6030 ideal for a variety of assembly operations. AT-6030 is packaged in 40ML cartridges for use with our AT-300 dispensing gun and AT-650 mixing tips. AT-6030 is used typically for bonding Weld Mount parts in the heaviest duty applications.

Technical Information

Weld Mount System advantages:

  • Eliminate the need to drill in to a composite skin and exposing the core
  • Eliminate drilling, tapping, welding, grinding and finishing steps
  • Eliminate costly rework expenses caused by inadvertently drilling though substrates
  • Eliminate blocking added during lamination in order to have a place to put screws
  • Much stronger than traditional methods
