Document: Dynamic Mixing System Best Practices
Preventing pinholes means outstanding results. The secret to a better finish with the 3M™ Dynamic Mixing System lies in the vortex-like action occurring in the mixing nozzle. Within this sealed environment, no air is allowed to enter when the filler or glaze and hardener are mixed to a perfect ratio.The absence of air in the cartridge and mixing nozzle virtually eliminates problematic pinholes in the final finish – pinholes that are simply unavoidable using traditional mixing techniques.
