LORD Accelerator 19 & 19GB - Hardener for Lord MMA Acrylic Resins
LORD® Accelerator 19 and 19GB are mix-in curatives designed for use with LORD acrylic adhesives.
LORD Accelerator 19 and 19GB, when mixed with LORD 200, 400
or 500 series acrylic adhesives, create adhesive systems that will bond a variety of prepared or unprepared metals and plastics.
LORD Accelerator 19GB has embedded glass micro-beads, which allows precise control of adhesive bondline thickness, 0.01" (0.025 cm) diameter.

Features and Benefits:
- Convenient – provides room temperature cure with all LORD acrylic adhesives.
- Environmentally Recommended – contains no solvent, non-flammable and virtually odorless.
- Environmentally Resistant – resists common environmental conditions when used with LORD acrylic adhesives.
- Temperature Resistant – improves high temperature resistance of LORD 200, 400 and 500 series acrylic adhesives.
Application (how to apply):
Mixing – Confirm the proper mix ratio of acrylic adhesive to accelerator by consulting the appropriate LORD acrylic adhesive data sheet. Thoroughly mix the proper amount
of adhesive and accelerator until uniform in color and consistency. Be careful not to whip excessive air into the adhesive system.
Heat buildup due to an exothermic reaction between the two components will shorten the working time of the adhesive. Mixing smaller quantities will minimize heat
buildup.
Applying – Apply adhesive to substrate surfaces using handheld cartridges or automatic meter/mix/dispense equipment. Mate the parts within the working time of the adhesive. Clamp in position until handling strength is achieved.
Curing – Handling strength and complete cure times will vary depending on acrylic adhesive used. For cure times, refer to appropriate acrylic adhesive data sheet.
Cleanup – Clean equipment and tools prior to the adhesive cure with hot water and detergent or an organic solvent such as methyl ethyl ketone (MEK). Once adhesive
is cured, heat the adhesive to 400°F (204°C) or above to soften the adhesive. This allows the parts to be separated and the adhesive to be more easily removed.
Shelf Life/Storage:
Shelf life is nine months when stored at 60-80°F (16-27°C) in original, unopened container.
