Premium, Surface InsensitiveThis line of instant adhesives provides the best combinationof speed, strength and high temperature performance. Theyare uniquely formulated to attain high bond strengths on thewidest range of materials, including dry or acidic surfaces.

Although fixture speeds will range by substrate material,many yield speeds of 15 seconds or less, such as steel,aluminum, ABS, PVC, polycarbonate, nitrile rubber, paper,balsa wood and phenolic to name a few. These PremiumInstant Adhesives are available in a wide range ofviscosities and most offer temperature resistance up to250F (121C).

For manufacturing operations where rapid assemblyspeeds are critical, two categories of instant adhesivesare available. Loctite Premium Surface InsensitiveInstant Adhesives provide fixture speeds less than15 seconds on many substrate materials while Loctite Light Curing Instant Adhesives provide fixture speedsless than 5 seconds on most substrate materials. ApplyLoctite Accelerators to reduce fixture/cure times and tocure exposed adhesive.

Light-CuringThese patented products provide twocuring mechanisms, the first initiated bythe introduction of light energy and secondby surface moisture present on the almostall substrate materials. Applying theproper light energy to adhesive exposedin open air, or through a transparentsubstrate, allows components to betacked together in as little as 2 to 5seconds. Shadowed areas of the bondline where light cannot reach will alsocure via the standard cyanoacrylatemoisture-curing mechanism, reachingfixture strengths in 5 to 25 seconds, andfull bond strengths in 24 hours.

the continued curing of the CA in the shadowed areaof the bond line in 5 to 20 seconds via the conventionalsurface moisture curing mechanism. Light curing cya-noacrylate adhesives offer unique performance benefitsfor high-speed assembly processes. By rapidly curingexposed and confined adhesive without requiring the

use of heat or racking of parts, light cure cyanoacrylatesprocess quickly, are easy to use and are reliable.

What is blooming? Blooming is a phenomenon uniqueto cyanoacrylates that manifests itself as a rainbow hazeor whitish haze surrounding a bond line. Un-reactedcyanoacrylate molecules can leave the surface of thedispensed adhesive and become airborne, only to laterfall back onto the surface of the substrate. When theyland, the molecules react with surface moisture andadhere themselves to the substrate. This small concen-

tration of cyanoacrylate particles on the surface canbe diffracted by light causing the rainbow effect, whilehigher concentrations can result in a whitish haze onthe substrate. A number of options exist to minimize oreliminate blooming as listed:

Use low odor/low bloom products Avoid large fillets

Increase air flow

Avoid acidic surfaces

Avoid extremes in relative humidity

Avoid extremes in temperature

Avoid vacuum environments

Avoid the use of old material

How do conventional CAs cure? Cyanoacrylateadhesives are acrylic resins that polymerize or curerapidly when exposed to alkali surfaces. Water, which isfound in trace amounts on virtually all surfaces, containshydroxyl ions which are alkaline and thus trigger rapidpolymerization, whereby CA molecules link up to form

a very strong and durable thermoplastic material. CAsreach fixture strength, or the strength where assembliescan be handled without falling apart, very quicklytypically in 5 to 20 seconds depending on the assembly.CAs reach their full strength in 24 hours, often attaininglevels of 2,000 to 3,500 psi depending on the materialsbonded. Very dry or acidic surfaces can also be bondedusing Loctite Surface Insensitive cyanoacrylateproducts. Cyanoacrylate adhesives that do not contacta surface, but are left in open air, will cure due to atmo-spheric moisture, but very slowly. To quickly cure CA

exposed to open air, either spray on an accelorator, oruse a two-part CA.

How do light cure CAs cure? Light-curing cyanoac-rylates are uniquely versatile as they offer the benefitsof a conventional cyanoacrylate as well as the benefits

of a light cure adhesive. These products will cure asdescribed above, typically reaching fixture strengths in5-20 seconds. They can also reach fixture strengthsin 2-5 seconds with the introduction of the proper lightsource. Light cure CAs contain additives called photo-initiators which react when exposed to light of theproper wavelength and intensity to initiate the polym-erization process extremely rapidly. Light that reachesthe adhesive, either through a transparent substrateor an exposed bond line, allows components to betacked together literally in a few seconds, followed by
