Product Introduction
3M™ Scotch-Weld™ Super Fast Instant Adhesive SF20 is a low-viscosity cyanoacrylate adhesive engineered for extremely rapid bonding. It is formulated to provide exceptional performance on difficult-to-bond substrates such as plastics and rubbers, particularly when used with an appropriate primer. With a handling time of under 5 seconds, this adhesive is ideal for high-speed assembly and repair jobs. Its low viscosity allows it to wick into tight-fitting joints for a secure bond. Once fully cured, SF20 creates a strong and durable bond with an overlap shear strength exceeding 2,000 psi. The flexible container enables precise application with just a pinch or a squeeze.
3M™ SF20 Features:
- Bonds effectively to difficult substrates, including various plastics and rubbers.
- Super-fast cure speed reaches handling strength in under 5 seconds.
- Enables precise application from a flexible pinch or squeeze container.
- Low viscosity adhesive is ideal for wicking into tight gaps and joints.
- Creates a strong, durable, and long-lasting bond on multiple substrates.
3M™ SF20 Applications:
- Gasket attachment and sealing.
- Assembly of small joints and components.
- Jewelry assembly and repair.
- Applications in orthopedics and footwear manufacturing.
- High-speed production lines requiring rapid bonding.
