Loctite Prism 401 Clear Multi-Surface Instant CA Adhesive-General Purpose (40140, 40104, 40161)

Product Name

Loctite Prism 401 Clear Multi-Surface Instant CA Adhesive-General Purpose (40140, 40104, 40161)

Brief Description

Loctite 401 is a fast-fixturing, clear, low to medium viscosity, surface-insensitive cyanoacrylate instant adhesive. It is designed for general-purpose industrial bonding of a wide range of materials, including difficult-to-bond and porous substrates, where uniform stress distribution and high tensile and/or shear strength are required.

Popular Applications & Uses

- Rapid bonding of a wide range of metal, plastic, or elastomeric materials- Assembly of close-fitting parts- Bonding porous or absorbent materials such as wood, paper, leather, and fabric- Fast assembly in production lines- Quick repairs- Bonding dissimilar substrates

Industries that Commonly Use It

- Artist, Artisan- Automotive Service/Repair- Cabinet & Woodworking- Electrical Services or Products (for electronics)- Furniture- General Manufacturing- LED/Electronics- Medical Device/ Prosthetics- Metal Fabrication- Packaging Services or Contractor- Plastic Fabrication- PVC Trimboard- Special Effects/ Scenic Design- Tarp, Fabric, Awning Manufacturing- Thermoforming

Special and Unique Features

- Universal industrial instant adhesive- Very high-strength on close-fitting parts- Surface-insensitive properties, allowing effective bonding with almost any substrate- Reduced hazardous ingredients for improved occupational safety- Improved high-temperature formula, withstanding up to 250 °F (120 °C)- Clear formula that disappears completely upon drying for clean, invisible bonds- Fast fixture speed, typically 5 to 20 seconds- Low to medium viscosity, enabling it to wick into tight cracks and capillary spaces

Surface Compatibility

- Metals- Plastics (most common plastics, and difficult-to-bond plastics with primer like LOCTITE SF 770)- Elastomers / Rubber- Wood- Paper- Leather- Fabric- Cardboard- Ceramics

Known backups / known substitutes

- Permabond 910- Cyberbond 100 Series- 3M CA4- Hernon Ultracure 100- Procure PC01 (Medium Cyanoacrylate Adhesive)- Infinity SI 120 (Surface Insensitive Super Glue)

Comparison Note

Loctite 401 is a high-performance industrial-grade cyanoacrylate adhesive, offering superior bonding strength, faster curing times, and broader material compatibility compared to regular super glues. It is particularly effective on porous materials and for general-purpose tasks. In contrast, Loctite 406 is typically recommended for bonding flexible plastics and rubbers where impact resistance and flexibility are crucial.
