3M 7000046526 Instant Adhesive CA8 Clear 1 Fl Oz

Product Description

The 3M 7000046526 Scotch-Weld Instant Adhesive CA8 is a fast-setting, low-viscosity cyanoacrylate adhesive formulated for bonding metal, plastic, and rubber substrates. Supplied in a 1 fl oz bottle, CA8 delivers stronger shock and impact resistance than many standard instant adhesives, making it a reliable choice for field repairs and production assembly where joint durability under vibration or mechanical stress is required. It meets CID A-A-3097, Type II, Class 2, confirming it to a recognized government specification for instant adhesives. Licensed technicians and maintenance professionals across HVAC, electrical, and general industrial trades use CA8 wherever a fast, structural-grade bond on dissimilar materials is needed.

CA8 is suited for applications involving metal-to-metal, metal-to-plastic, and metal-to-rubber bonds in both residential and light commercial service environments. Its low viscosity allows it to wick into tight-fitting joints through capillary action, which is useful when bonding close-tolerance assemblies or retrofitting components with minimal surface gap. Typical install scenarios include bonding sensor housings, gasket retention, component repair on control assemblies, and fixture bonding where thermal cycling or vibration may challenge conventional adhesives.

Key Features

• Fast-setting, low-viscosity formula wicks into tight joints via capillary action
• Bonds metal, plastic, and rubber substrates in a single product
• Higher shock and impact resistance compared to many standard instant adhesives
• Meets CID A-A-3097, Type II, Class 2 government specification
• Clear cure color for clean, unobtrusive bond lines
• 1 fl oz bottle suitable for field service and bench repair use

Compatibility

Designed for bonding metal, plastic, and rubber surfaces. Performs on close-tolerance assemblies where low-viscosity capillary penetration is required. Verify substrate compatibility and surface preparation requirements before application on porous or coated materials.

Installation Notes

Application should be performed by trained maintenance or trade personnel following standard adhesive safety practices. Ensure all surfaces are clean, dry, and free of oils or contaminants before bonding. Work in a well-ventilated area; cyanoacrylate adhesives bond skin rapidly, so appropriate nitrile gloves and eye protection are required. Avoid applying to poorly fitted joints with large gaps, as low-viscosity cyanoacrylates are optimized for tight-fitting surfaces.
