Four Decades of Chemistry.
Three Generations of Commitment.

We still formulate our products in-house, with the same hands-on attention to quality that has defined Anchor Seal since 1979.

Built to perform

Anchor Seal has been in our family for three generations, and that shapes the way we do business. We’re large enough to support demanding applications and customers around the world, but still small enough to know our customers by name, understand the problem they’re trying to solve, and stay involved until we get it right.

We also genuinely love this work. We’re chemists, problem-solvers, and, yes, more than a few of us are materials nerds. We care about the details because the quality of what leaves our facility matters to us personally. Whether we’re refining a product we’ve made for years or developing something completely new, the standard is the same: make it perform, make it consistently, and stand behind it.

That combination—technical capability, personal attention, and a real sense of ownership—is what Anchor Seal has been built on since 1979. And it’s what we intend to keep building on.
