- Question & answer
When you need an instant adhesive with excellent gap-filling capabilities on a variety of substrates, LOCTITE® 3090 is a great choice. This 2-part product is designed for assembling parts with varying or undefined bond gaps up to 5mm (0.2"), or for applications where complete cure of excess adhesive is a must. It has excellent bonding characteristics to a variety of substrates, including plastics, rubbers, metals, and even porous materials like wood, paper, leather and fabric. The gel consistency prevents adhesive flow even on vertical surfaces, and temperature resistance is from -40°C to 80°C (-40°F to 176°F). For best application results, use the LOCTITE cyanoacrylate mixing nozzle contained in the kit.

How to use
It is recommended to use the correct LOCTITE® cleaner for the surface to be bonded (such as LOCTITE® SF 7063 or SF 7070) to degrease and clean surfaces prior to applying the adhesive.
Place plunger in the back of the cartridge. Remove cap from cartridge. Dispense a small amount so that material is coming out of both sides. Attach mix nozzle and dispense a bead at least half of the length of the nozzle. The material is ready to use.
Apply a bead of material to one of the surfaces to be bonded. Join the parts and fixture in a way to prevent movement of the part until handling strength is obtained.
Assemble parts immediately. The parts should be accurately located as the short fixture time leaves little opportunity for adjustment. Bond should be held or clamped until the adhesive has fixtured. Hint: if necessary, excess product can be cured by activator LOCTITE® SF 7455 or LOCTITE® SF 7452. Spray or drop activator onto excess product.
FAQ
Although HQ is not part of the product formula for LOCTITE® 3090, trace amounts are possible due to shared manufacturing processes and/or select raw material impurities. Hence, Henkel has taken the additional step of introducing a low specification level (< 50 PPM for HQ) and each batch is now checked for this after manufacture.
This is called blooming. This often occurs when there is an excessive amount of product being applied. To avoid blooming, use proper ventilation, less product, lower humidity, use a primer/accelerator, or a low bloom product.
This is a result of stress cracking. Leaving uncured liquid CA remaining on some plastic substrate (such as polycarbonate, acrylic, and polysulfone) in a stressed condition may cause the formation of cracks in the plastic. Some remedies for avoiding/minimizing stress cracking are closing the bond joint quickly, use reinforced grades of plastic, anneal parts, or speed the cure of the CA with accelerator (or light for light curing CA products only)
Yes, CA’s should be stored in the refrigerator prior to opening, but DO NOT refrigerate them once they have already been opened. After opening, CA's should be used within 30 days for best performance.
Henkel has several products available with varying levels of NSF® and WRAS® approval, amongst others. Please contact the Henkel sales or technical teams with your requirements.
All necessary H&S measures and PPE (personal protection equipment) requirements can be found on the product material safety data sheet, all of which are available via our website.
Yes, LOCTITE® 3090 is a two-part product. Bumping and purging ensures product is flowing from both sides and mix at the proper ratio.
