I used a new tube of this locktite a week ago and spilled it on
plastic, it is still liqued, how can it work since it hasnt cured,
doesnt Blue locktite cure hard? Is my tube a defect or old.

as per the other replies......loctites are anaerobic adhesives..

specialily formulated to harden in the interstitial space between male
& female fastening elements (or between rod & hole as for slip fits
or bearings in a recess)

Loctite stays liquid & uncured in the bottle or tube because of the
air contained within.

Blue loctite cures "hard" but can be defeated with hand tools...red
loctites usually require high heat to defeat.

Lotittes that I typically use

242, 243 "blue types" 243 esp good as a gap filler for Class 1
threads & faster cure
271 "red" "permanent" be sure you really want this assembly to
not come apart or can heat it to 350F+
680 "green" for slip fits

www.mcmaster.com is both a source of loctite & information about
loctites
