LORD® 810 Low Read-Through (LRT) acrylic adhesive when cured with LORD® Accelerator 20GB creates a flexible adhesive system for bonding metals, such as aluminum, galvanized steel and CRS, and engineered plastics, such as PC-ABS. LORD® 810 adhesive in combination with LORD® Accelerator 20GB delivers fast cure speed and strong bonding with minimal bondline read through (BLRT).

LORD® Accelerator 20GB allows precise control of the adhesive bondline thickness due to its content of glass beads. For further detailed information, refer to the LORD® Accelerator 20GB data sheet.

Shelf Life/Storage

N/A Shelf life is one year when stored below 77 ºF (25 ºC) in original, unopened container. Storage temperatures of 40-60 ºF (4-15 ºC) are recommended. If stored cold, allow product to return to room temperature before using. Protect from exposure to direct s

Features

Aesthetics

N/A Bonds thin and flexible substrates with little to no bondline read-through.

Convenient

N/A Requires little or no substrate preparation for bonding metals and plastics.

Environmentally Resistant

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

Temperature Resistant

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

Non-Sag

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

Applications

Surface Preparation

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.

Applying

N/A Apply the mixed adhesive to bond surfaces using a handheld cartridge or automatic meter/mix/ dispense equipment. Contact your LORD® representative if assistance is needed using this equipment.

Mixing

N/A Mix LORD® 810 adhesive with LORD® Accelerator 20GB at a ratio of 2:1, adhesive to accelerator, by volume. Even color distribution visually indicates a thorough mix. Once mixed, the adhesive system cures rapidly.

Curing

N/A Initial cure (90% cure strength) is achieved after 30 minutes at room temperature [77 ºF (25 ºC)]. 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 [<105 ºF (<66 ºC)]

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.
