Non-Hazardous flushing agents that clear wet, sticky polyurethane from hoses, mixing heads and machinery — before it has a chance to cure and harden.

Why Uncured Polyurethane Needs a Different Approach

Unlike cured PU, uncured polyurethane is still wet and reactive — and that changes everything about how you need to clean it. While it remains wet, PU is extremely sticky and resistant to standard cleaning products. In fact, using a water-based product only accelerates curing, making the residue even harder to remove.

In production machinery, you need PU to stay wet and liquid as it pumps through hoses and tubes toward a mixing head before pouring, so you can’t afford for any residue to harden along the way. Flush and remove these wet mixtures from pipes and mixing heads quickly, and your production process runs smoothly. Fail to, though, and you risk breakdowns and blockages that are expensive and time-consuming to clear.

Our Uncured Polyurethane Flushing Products

At Bio8 Industrial Ltd, we’ve developed a combination of non-hazardous, extremely effective products to remove uncured polyurethane.

Unlike standard flushing chemicals, our formula doesn’t evaporate — every drop stays focused on cleaning. It quickly dissolves the wet, sticky PU mixture, stopping it from curing into a hardened state and binding to tubes, mixing heads and dispensers. At the same time, it helps flush the waste PU mixture straight through the head and pipes.

For more information about our non-hazardous PU flushing agent, see EN720 Non-Hazardous PU Flushing Agent below.
