AI Technical Summary

Technical Problem

Existing methods for applying high-viscosity materials, such as sealants, over large surface areas face challenges with air entrapment, uneven thickness, and non-uniform coverage, which can affect the properties of the cured sealant and increase environmental and health risks due to solvent use.

Method used

An extrusion applicator with a diverging transition section and adjustable nozzle section, combined with a flow and pressure control mechanism, applies high-viscosity materials efficiently with minimal air entrapment, ensuring uniform thickness and coverage.

Benefits of technology

The applicator provides a controlled, uniform coating of high-viscosity materials over large areas with reduced solvent use, enhancing aesthetic and functional properties while minimizing environmental impact.
