Request Information
LORD® 506 acrylic adhesive when cured with LORD® Accelerator 4, 17 or 19 creates a semi-flexible adhesive system that will quickly bond a wide variety of thermoplastics and thermoset plastics.

LORD® 506 acrylic adhesive can be mixed with either LORD Accelerator 4, LORD® Accelerator 17 or LORD® Accelerator 19. LORD Accelerator 4 is a no-mix accelerator applied to the substrate before the acrylic adhesive. LORD® Accelerators 17 and 19 must be mixed into the acrylic adhesive prior to application. LORD® Accelerator 19 is available in off-white or black. For further detailed information on LORD® Accelerator 4, LORD® Accelerator 17 and LORD® Accelerator 19, refer to the applicable data sheet.

Features

Versatile

 N/A Bonds a wide variety of substrates including ABS, acrylic, polycarbonate, FRP, prepared metals, urethane, phenolic, polysulfone, and vinyl, can be used with both Mix-In and No-Mix accelerators.

Convenient

 N/A Cures very quickly at room temperature.

Durable

 N/A Accommodates shock and sudden stress loading.

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 and moisture; provides excellent resistance to indirect UV exposure and weathering.

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.

Mixing

 N/A
  • No-Mix Accelerator
    LORD® 506 acrylic adhesive and LORD® Accelerator 4 are not mixed prior to application.
  • Mix-In Accelerator
    Mix LORD® 506 acrylic adhesive with the proper amount of LORD® Accelerator 17 or 19. 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.

Applying

 N/A
  • No-Mix Accelerator
    Apply LORD® Accelerator 4 to one or both substrate surfaces. Allow accelerator to dry. For further details on the use of LORD Accelerator 4, refer to the LORD® Accelerator 4 data sheet.

    Once accelerator is dry, apply adhesive to the other substrate surface using a handheld cartridge or automatic dispense equipment. Mate the two surfaces and slide into correct position within the working time of the adhesive.
  • Mix-In Accelerator
    Apply mixed 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.

    Meter/Mix/Dispense Equipment
    Contact your LORD representative if assistance is needed using this equipment. When using such equipment, all wetted parts must be made of stainless steel and all hoses should be PTFE-lined high pressure hose.

Curing

 N/A Cure begins immediately once adhesive and accelerator come in contact. Handling strength is achieved within 8-12 minutes. Complete cure will take 24 hours at room temperature. Mating surfaces should be fixtured as soon as possible (within 4-6 minutes) after adhesive application.
