3M™ High Performance Industrial Plastic Adhesive 4693H.
3M High Performance Industrial Plastic Adhesive 4693H is a solvent-based, synthetic elastomer adhesive engineered for strong, flexible, weather-resistant bonds to plastics and many other materials, with applications in industrial assembly and repair. It dries quickly at room temperature and is resistant to water and cleaning chemicals, making it suitable for demanding environments.
Key Features
High performance plastic adhesive that forms strong, flexible bonds primarily on plastics.
Bonds to difficult-to-adhere plastics such as polypropylene (PP), polyethylene (PE), and polyolefin blends (TPO).
Also adheres well to ABS, PMMA (acrylic), nylon, polyester, and rigid polystyrene.
Resists weathering, water, and cleaning products, making it durable for long-term use.
Quick drying with an open bond time ~20 min, allowing faster assembly.
4693H is the higher viscosity version that is best applied as beads (vs. brush application).
Typical Applications
This adhesive is designed for industrial and maintenance uses, including:
Bonding most plastics, including hard-to-bond polymer parts.
Repairing plastic components in assemblies (large and small).
General industrial assembly and MRO (maintenance, repair, and operations).
Plastic to plastic joining in products requiring durable, weather-resistant bonds.
