SIKA® Shield: A New Standard in Ballistic Materials

SIKA® Shield: The Future of Defense Materials

For thousands of years, the story of armor has been the story of finding something harder, something lighter, something better.

Wood and hide gave way to bronze. Bronze gave way to steel. Steel gave way to Kevlar. Each leap forward didn’t just change what soldiers carried — it changed how threats were met and what survival looked like on the battlefield.

But every generation of armor material carried compromise. Bronze was hard but heavy. Steel was strong but slow. Kevlar stopped bullets but couldn’t stop everything. And when boron carbide emerged as the hardest practical armor ceramic available — lighter than alumina, harder than silicon carbide — it looked like the endgame.

It wasn’t. Not yet.

Conventional boron carbide carries flaws baked into its manufacturing. Free elemental carbon weakens the ceramic from within — sitting at grain boundaries, creating failure points under impact. And surface oxidation degrades the powder over time, reducing consistency and undermining performance before the material ever reaches a finished armor plate.

Armor designers have worked around these limitations for years. SIKA® Shield eliminates them.

A New Starting Point

Developed by Kymera International, SIKA® Shield is a submicron boron carbide powder produced through proprietary processing methods that achieve near-complete elimination of elemental carbon and enhanced oxidation protection. What remains is a cleaner, more stable, more consistent material that sinters into denser, more uniform armor ceramics — fewer defects, fewer weak points, and greater stopping power at lower weight.

This isn’t a refinement of the old process. It’s a fundamentally different foundation for the next generation of ballistic protection — from personal body armor to vehicle, marine, and aircraft survivability systems.

The Next Chapter

Every era of defense has been defined by a breakthrough material. SIKA® Shield is Kymera International’s contribution to that timeline — the moment boron carbide finally sheds its last compromises and delivers on its full potential.

The future of defense materials has arrived.
