Description
When precision matters, reach for Loctite Prism 420. This water-thin, ultra-low viscosity instant adhesive is designed to wick deep into pre-assembled joints and hairline cracks, locking parts together instantly via capillary action. Ideal for metals, plastics, and rubbers, its the professional’s choice for tamper-proofing, penetrating repairs, and high-speed assembly where standard glues can’t reach.
Loctite 420 Ultra-Low Viscosity, Wicking (Water-Like, Water-Consistency) Multi-Surface Instant Adhesive is a clear, ultra-low viscosity (2cP), one-part instant adhesive designed for OEM assembly of difficult-to-bond materials, and most plastics. Loctite 420’s improved formula allows high bond strength and speed up to temperatures of 250 F and is suited for bonding a wide range of materials, including metals, plastics, and elastomers. Formerly known as Loctite420 Prism.
