Benefits of technology

This patented technology describes a new type of cleaning agents that have stronger surfaces than regular water or oil based products like olefinic acid polymers (OEP). These treatments help remove dirt from these items without harmful chemicals used during their production process. They improve durability when exposed to harsh environments over time. Additionally, they provide better flexibility compared to traditional methods due to its unique design features. Overall, this innovative product provides technical benefits including enhanced functionality, reduced waste generation, increased efficiency, ease of application, and long-lastingness.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the properties required for different applications like clothing products or sport items. Current methods involve adding chemical substances called tackifiers or plasticizers to improve these qualities while reducing their negative impact upon environments. Existing solutions require complicated manufacturing processes involving multiple steps, resulting in increased expenses associated with each step. There also exist concerns over safety hazards due to residual unreactable ingredients from certain sources.
