Choosing the right option
Loctite AA 330 is the higher viscosity of the two activator-cured acrylics here and comes as a cartridge. For a medium viscosity liquid in a smaller pack, see Loctite AA 324 Structural Adhesive 50ml.
The activator is Loctite 7387 Activator 100ml.

Using it
Apply the activator to one surface and the adhesive to the other, and assemble within 15 minutes. For larger gaps or a faster cure, apply the activator to both surfaces and assemble within 1 minute.
Hold the parts clamped until the adhesive has fixtured.
Full strength is typically reached in 24 to 72 hours, depending on bond gap, materials and conditions. The recommended bondline is 0.1mm, with a maximum gap of 0.5mm.
Storage and handling
Store unopened, in a dry place, between 8 °C and 21 °C. Storage below 8 °C or above 28 °C can adversely affect the properties of the product. Do not return used product to the container.
Limits and safety
Not recommended for pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidising materials. Resistance to acetone and unleaded petrol is low. The NSF P1 registration is a regional approval; confirm it with your local Henkel Technical Service Centre. Read the safety data sheet before use.
Not well.
After 350 hours it keeps 10% of its initial strength in acetone and 20% in unleaded petrol.
