LOCTITE 3090 TWO COMPONENT GEL 11G 1379599

LOCTITE® 3090 is a two-component, fast-curing cyanoacrylate instant adhesive designed for bonding parts with varying or undefined gaps up to 5 mm. Its gel consistency prevents adhesive flow, including on vertical surfaces, while its gap-filling capability makes it suitable for assemblies where conventional instant adhesives may not accommodate the required bond gap. It bonds a wide variety of substrates, including plastics, rubbers, metals and porous materials such as wood, paper, leather and fabric. The mixed adhesive is clear and provides an operating temperature range of -40°C to +80°C.

Features:
LOCTITE® 3090 uses ethyl cyanoacrylate technology in a two-component system that cures after Part A and Part B are mixed. Part A is a clear to slightly cloudy gel, while Part B is a transparent, colourless liquid; after mixing, the product forms a clear to slightly cloudy thixotropic gel. Its open time at 25°C is 90 to 180 seconds. Handling strength develops rapidly after mixing, while full strength is achieved over 24 hours. The adhesive is specifically designed for applications requiring complete curing of excess adhesive and provides low blooming. Its performance extends beyond non-porous engineering materials to porous substrates, providing a single bonding solution for a broad range of material combinations.
