M CA40H is a high-strength cyanoacrylate quick drying adhesive (instant adhesive) produced by 3M Company in the United States. It has a medium viscosity (400-600cP) and a slow curing speed (initial curing in 5-40 seconds, complete curing in 24 hours), designed for bonding various difficult to stick materials such as EPDM rubber, flexible ethylene resin, metal, plastic, etc. Its transparent liquid formula complies with MIL-A-46050C Type II, Class 3 standards and is suitable for industrial, electronic, and home repair scenarios
As a star product in the 3M Scotch Weld series, CA40H optimizes viscosity and curing time based on traditional cyanoacrylate adhesives. Its high viscosity characteristics can effectively fill gaps below 0.1mm, and the curing speed is slower (compared to the CA40 model), providing users with longer component alignment time. This adhesive can cure at room temperature without the need for a catalyst, and the single component design simplifies the operation process. Only a few drops are needed to achieve high-strength bonding (the lap shear strength of steel can reach 1500psi). In addition, it exhibits excellent tolerance to soap and isopropanol, making it suitable for use in humid environments
Material compatibility: Especially suitable for bonding difficult to bond materials such as aluminum, ethylene propylene diene monomer (EPDM), and flexible vinyl, breaking through the limitations of general instant adhesives.
Process advantages: Medium viscosity (400-600cP) balances fluidity and anti drip performance, suitable for vertical surface construction; After curing, a flexible adhesive layer is formed, which has better impact resistance than ordinary quick drying adhesive.
Safety and Environmental Protection: The low odor formula complies with RoHS standards, but should be used in a well ventilated environment to avoid contact with skin and eyes.
Long term stability: unopened shelf life of 15 months (stored below 27 ° C), low temperature can extend storage time
Automotive manufacturing: adhesive sealing strips, rubber gaskets, and shock absorbers (EPDM rubber)
Electronic assembly: fixing flexible circuit boards, USB flash drive casings, and electronic components (plastic/metal composite bonding)
Home repair: repairing broken parts of furniture, ceramic decorations, and glass products
Industrial field: Assembly of small components for portable printers, pasting of hardware nameplates
Creative DIY: Model making, jewelry inlaying, and woodworking fixation
