N/A Typical shelf life is nine months when stored below 80 ºF (27 ºC) in original, unopened container. Storage temperatures of 40-50 ºF (4-10 ºC) are recommended. If stored cold, allow product to return to room temperature before using. Protect from exposure

Features

Versatile

N/A Bonds a wide range of unprepared metals with minimal substrate preparation, as well as engineered thermoplastics including XENOY®, polycarbonate, ABS and acrylics.

Temperature Resistant

N/A Performs at temperatures from -40 ºF to +300 ºF (-40 ºC to +149 ºC).

Environmentally Resistant

N/A Resists dilute acids, alkalis, solvents, greases, oils, moisture, salt spray and weathering; provides excellent resistance to indirect UV exposure.

Non-Sag

N/A Remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.

Underwriters Laboratories (UL) Rated

N/A When mixed with LORD® Accelerator 19, adhesive system is UL 746C certified.

Applications

Surface Preparation1 N/A Remove grease, loose contamination or poorly adhering oxides from metal surfaces. Normal amounts of mill oils and drawing compounds usually do not present a problem in adhesion. Most plastics require a simple cleaning before bonding. Some may require abrading for optimum performance.

Mixing

N/A Mix LORD® 403, 406 or 410 acrylic adhesive with the proper amount of LORD® Accelerator 19 or 19GB. Handheld cartridges will automatically dispense the correct volumetric ratio of each component. Even color distribution visually indicates a thorough mix. Once mixed, the adhesive cures rapidly.

Curing

N/A Cure begins immediately once adhesive and accelerator are mixed. Time to handling strength is dependent on adhesive used. Complete cure requires 24 hours at room temperature. Mating surfaces must be held in contact during the entire curing process. Cure rate can be accelerated by applying modest heat [<150 ºF (<66 ºC)]. Cured adhesive is colored to visually indicate a full cure; cure color depends on the accelerator used.

Cleanup

N/A Clean equipment and tools prior to the adhesive cure with solvents such as isopropyl alcohol, acetone or methyl ethyl ketone (MEK). Once adhesive is cured, heat the adhesive to 400 ºF(204 ºC) or above to soften the adhesive. This allows the parts to be separated and the adhesive to be more easily removed.

Applying

N/A Apply adhesive using handheld cartridges or automatic meter/mix/dispense equipment.
  • Handheld Cartridges
  1. Load the cartridge into the applicator gun and remove the end caps.
  2. Level the plungers by expelling a small amount of adhesive to ensure both sides are level.
  3. Attach mixing tip and expel a mixer's length of adhesive.
  4. Apply adhesive to substrate and mate the parts within the working time of the adhesive. Clamp in position until adhesive reaches handling strength.
Do not re-expose adhesive to air once parts are mated. Mated parts should be repositioned by sliding to achieve proper alignment.

Additional Information

Additional Information

N/A LORD® 403, 406 and 410 acrylic adhesives, when mixed with LORD® Accelerator 19 or 19GB, create adhesive systems that bond a wide variety of prepared or unprepared metals and engineered plastics. These adhesive systems are specifically formulated to provide the highest impact and peel strengths available in a room temperature curing adhesive.

LORD® 403, 406 and 410 acrylic adhesives can be mixed with either LORD® Accelerator 19 or LORD® Accelerator 19GB. LORD® Accelerator 19 improves the high temperature resistance of LORD® 403, 406 and 410 acrylic adhesives, and is available in off-white or black. LORD® Accelerator 19GB allows precise control of the adhesive bondline thickness due to its content of glass beads. LORD® Accelerator 19GB is available in off-white, red or Gray. For further detailed information, refer to the LORD® Accelerator 19 and 19GB data sheet.
