Benefits of technology

Inventions described by these inventors have several technical benefits compared to existing products that use expensive ingredients like dequanisers from China's mainland crop plants. These improvements include low costs due primarily to their cheap sources, fast drying speeds at high levels, resulting in improved quality control during production processes, long shelf life without losing effectiveness overtime, strong adhesion between different layers when applied on various surfaces, minimal residue left after cleanings, and nonyellow appearance under sunlight exposures. Additionally, they provide an ideal solution for producing varnses containing both soluble components and insoluble particles called filler material.

Problems solved by technology

This patented technical problem addressed in the current technology for producing high quality repairs involves finding an affordably quick yet effective way to make sure they don't get wet or too soft during use.
