One-Pack Epoxy Adhesive Systems: New Technologies, New Applications
Competitive pressures have driven manufacturers to improve productivity, increase product quality and reduce product-handling hazards. These factors have created an oppor- tunity for epoxy-adhesive and coating formulators to deliver a value-added, one-pack replacement for conventional plural-component systems. Recent advances in latent curatives have enabled formulators to develop one-pack systems covering a wide range of assembly applications — uses as diverse as filament winding, electronic coating and assembly, and innovative structural adhesives.
The product components are pumped either directly from shipping containers or transferred into reservoirs. Each component is delivered to a gear or piston metering pump that dispenses the prescribed volume of each component in relation to its mix-ratio requirement. The metered components then pass through either a dynamic or a static mixing element to deliver homogenous adhesive mixture to the assembly process.
