Arroyo 2K WB polyurethane topcoat is a hybrid waterborne interior topcoat that provides a very durable coating for interior projects, so finished work stands up better in demanding environments. This clear flat version controls sheen while still protecting the substrate, which helps installers deliver the low-gloss look many clients specify without sacrificing protection. The waterborne system supports interior use where strong solvent odors are restricted, keeping jobs more comfortable to work around. This topcoat is designed as part of a 2K system, so it uses a catalyst to reach its intended performance level, giving finishers a predictable path to a tough film. The product is offered under the ML Campbell Arroyo 2K WB polyurethane topcoat line, giving shops a consistent system identity when matching finishes across interior projects.
Arroyo 2K WB 2K topcoat clear flat is designed for easy application with fewer steps, which streamlines day-to-day finishing workflow. The self-sealing behavior means the same material builds both seal and top layers, reducing product changeovers during spraying. An unlimited application window lets crews stage parts and spray sequences without racing a recoat clock, which helps align finishing with other shop operations. Quick hardness development supports earlier stacking or assembly of interior components, keeping production lines moving. The flat sheen version helps finishers hit specified low-gloss targets directly from the gun, avoiding extra rubbing steps to knock down gloss after curing.
Arroyo 2K WB polyurethane topcoat is a hybrid waterborne system for interior use, so it fits projects finished and installed indoors. The clear flat sheen is useful where designers call for minimal reflection, helping hide minor surface irregularities once installed. Its high chemical and moisture resistance supports interior environments where cleaners or moisture contact are part of normal use, helping protect the appearance of finished surfaces. Because the system is low VOC with no HAPS option for SB VOC regulations, it serves shops working on interior millwork or casework in areas with tighter environmental rules, aligning finish selection with regulatory needs.
This very durable coating helps to improve your productivity, so the same system that protects the work also supports throughput targets. Easy application with fewer steps reduces the number of process handoffs during finishing, which cuts opportunities for variation between operators. The unlimited application window allows finishers to spray additional coats when the schedule permits rather than within a narrow band, which supports more consistent film build across complex runs. High chemical and moisture resistance helps surfaces stay stable in normal interior conditions, which reduces callbacks tied to finish failure. Quick hardness development supports earlier handling, helping parts move to fitting or installation stages without extended waiting periods. The product is available in flat, dull, satin, and gloss sheens, so once a shop dials in the system, the same product family can be used to match different sheen specifications while keeping similar application characteristics across jobs.
