Best Practices for Resinlab Armstrong A-661
Easy to apply
Bring both components to room temperature prior to mixing.
Cartridge format: Mixer should be attached keeping the cartridge vertical and any air pocket purged this way. After the mixer contains material, the mixer tip can be dropped to dispense pre-bleed amount. Attach a new static mixer with each cartridge, then pre-bleed the first 3 inches of dispensed material or until a uniform color is obtained. Maintain adequate velocity during dispensing to ensure complete mixing.
Bulk format: weigh and mix parts A and B accurately and thoroughly, scraping sides of container often. Do not pour from mixing container, transfer to a new container as residual unmixed material may cause a tacky spot on the surface of the casting. Maintain adequate velocity during dispensing to ensure complete mixing.
Allow to cure undisturbed until product is fully gelled or tack-free to the touch.
Clean up uncured resin with suitable organic solvent such as MEK, acetone or other organic solvent.
