Loctite 495 universal instant glue 20g bottle

LOCTITE 495 — Cyanoacrylate Instant Adhesive

LOCTITE 495 is a transparent, colorless, low-viscosity one-component cyanoacrylate adhesive for rapid curing. The product cures with ambient moisture and is formulated as a general-purpose instant adhesive for bonding plastic, rubber, and metals. The part numbers indicate that SKU 1921068 corresponds to a 20g bottle of LOCTITE 495.

Properties and Mechanism

• Technology: cyanoacrylate (ethyl cyanoacrylate).
• Appearance: transparent, colorless to straw-colored liquid (uncured).
• One-component; no mixing required — cures with atmospheric moisture.
• Low viscosity (stated as 20–45 mPa·s at cone & plate; Brookfield 20–60 mPa·s).
• Typical fixture time on steel: approximately 5.0 seconds (stated); gap fill 0.12 mm.

Application Advice

Surfaces should be clean and degreased before application. For low-energy plastics, LOCTITE SF 770 primer can be used to improve adhesion. The product should not be mixed and should be applied to one surface before assembly; short fixture times mean that parts must be positioned accurately. Full strength cure continues after initial fixturing and can last up to 24–72 hours depending on humidity, gaps, and materials.
