LOCTITE 3090/10G – Cyanoacrylate 2K Superglue

Loctite 3090/10G – Cyanoacrylate 2k Superglue

Loctite 3090 is a two component, fast curing, gap filling adhesive with excellent bonding characteristics to a variety of substrates including plastics, rubbers and metals. Loctite 3090 is designed for the assembly of parts with varying or undefined bond gaps up to 5 mm (0.2 in), or for applications where complete cure of excess adhesive is a requirement. The gel consistency prevents adhesive flow even on vertical surfaces. Loctite 3090 is also suited for bonding porous materials such as wood, paper, leather and fabric.

Typical Curing Performance

Cure Speed vs. Substrate
The rate of cure will depend on the substrate used. The graph shown in data sheet shows the shear strength developed with time on steel lap shears compared to different materials and tested according to ISO 4587.

Cure Speed vs. Bond Gap
The rate of cure will depend on the bondline gap. The graph shown in data sheet shows the shear strength developed with time on Polycarbonate lap shears at different controlled gaps and tested according to ISO 4587.

Cure Speed vs. Temperature
The rate of cure will depend on the ambient temperature. The graph shown in data sheet shows the shear strength developed with time at different temperatures on Polycarbonate lap shears and tested according to ISO 4587.
