Defender Hybrid was the first Brunswick ball featuring the groundbreaking new coverstock base, HK22. The motion was more hook in oil and more backend for a shiny ball than had ever been seen in the Brunswick line. HK22 balls have evolved significantly over the last year and a half. We’re excited to continue the evolution of the innovative cover base with the Ultimate Defender. This ball produces exceptional hook in the oil and impressive continuation on the backend because of the clean and strong nature of the cover despite the dull surface. The Ultimate Defender will be your ultimate choice when combating oily conditions. Compared to the Mindset, the Ultimate Defender will be cleaner and sharper while still handling the oil conditions.
HK22 - ACT 3.0 Hybrid Coverstock
The Brunswick Research and Development team has worked hard to develop the next breakthrough in cover technology. After pouring and throwing hundreds of bowling balls with dozens of new base reactive urethane formulations combined with a wide variety of chemical components and additives, our ball team has created something exceptional – the new HyperKinetic22 coverstock.
HK22, as we’ll often refer to it, features enhanced color and clarity by engineered nano micellular phase separation technology, dramatically improving the cover’s translucency. And through Quasi prepolymer staged reactions, intermolecular friction is reduced to manifest a dynamic interactive polymer morphology with the lane.
Bowling balls featuring HK22 look better on the shelf and perform better on the lanes with a shiny finish that provides easy length and increased dry lane friction for impressive backend reaction. HK22 is an exciting technological advancement, and we believe this is just the beginning as our chemists continue their work to push the limits of bowling ball performance.
