Product Introduction
3M™ Scotch-Weld™ Plastic & Rubber Instant Adhesive PR40 is a low-viscosity cyanoacrylate adhesive engineered for exceptional performance on hard-to-bond substrates. It excels at bonding materials like EPDM, nylon, polypropylene, and polyethylene, especially when used with an appropriate primer. This fast-acting “super glue” is easily dispensed from a flexible squeeze bottle for precise application, allowing for a thin, clean bond line. The PR40 achieves handling strength in under 15 seconds and a full, durable cure within 24 hours, delivering an overlap shear strength of over 2,000 psi. Its rapid cure speed helps accelerate production and improve workplace productivity.
3M™ PR40 Features
- Substrate Versatility: Specially formulated to bond difficult plastics and rubbers.
- Precise Application: Squeeze bottle allows for a precise drop or a steady bead.
- Low Viscosity: Flows easily into tight spaces for a thin, strong bond line.
- Rapid Cure: Reaches handling strength in under 15 seconds to keep jobs moving quickly.
- High Strength: Forms a strong, durable, and long-lasting bond on a variety of substrates.
3M™ PR40 Applications
- Gasket Attachment: Quickly and securely bonds rubber gaskets.
- Small Joint Assembly: Ideal for assembling small or intricate components.
