Loctite® 3105TM Light Cure Adhesive, Loctite® H3000TM SpeedbonderTM Structural Adhesive, Loctite® H4500TM SpeedbonderTM Structural Adhesive, Loctite® U-05FLTM Hysol® Urethane Adhesive and Loctite® 3631TM Hysol® Hot Melt Adhesive did not achieve substrate failure, but did perform well on ASA. Loctite® 5900® Flange Sealant achieved the lowest bond strength on ASA. Surface Treatments The effect of using Loctite® 770TM Prism® Primer, in conjunction with Loctite® 401TM Prism® Instant Adhesive, or Loctite® 4011TM Prism® Medical Device Instant Adhesive with Loctite® 7701TM Prism® Primer, could not be determined because both primed and unprimed ASA achieved substrate failure for most of the formulations evaluated. Surface roughening had an inconsistent effect on the bondability of ASA. Other Important Information • ASA can be stress cracked by uncured cyanoacrylate adhesives, so any excess adhesive should be removed from the surface immediately. • ASA is compatible with acrylic adhesives, but can be attacked by their activators before the adhesive has cured. Any excess activator should be removed from the surface immediately. • ASA is incompatible with anaerobic adhesives. • Surface cleaners: isopropyl alcohol, Loctite® ODC-Free Cleaner & Degreaser.

NOT TESTED: Substrate melted at adhesive cure temperature. The addition of the indicated additive (or surface roughening) caused a statistically significant decrease in the bond strength within 95% confidence limits. The addition of the indicated additive (or surface roughening) caused a statistically significant increase in the bond strength within 95% confidence limits.
