WB INTERIOR TOPCOAT 20 WHITE is a 2K waterborne white topcoat that provides an acrylic-polyurethane waterborne finish for interior projects where a controlled gloss level matters. This ML Campbell waterborne topcoat is designed as a topcoat layer in coating systems, so it works as the final film over compatible waterborne clear or pigmented basecoats. The acrylic-polyurethane waterborne topcoat chemistry delivers excellent surface hardness, supporting resistance to everyday contact on finished interior surfaces. Its 20 gloss level targets applications needing a low-sheen, uniform appearance that helps keep surfaces visually consistent across larger runs. The product is part of a gloss family that also includes 10, 40, and 90 levels, allowing shops to align sheen from sealer through topcoat in a system. For shops standardizing on waterborne processes, this 2K waterborne white topcoat supports a predictable interior finishing workflow.
This ML Campbell waterborne topcoat is intended as an interior topcoat layer in coating systems, so it functions as the final film over compatible waterborne clear or pigmented basecoats. Using it as the upper layer lets finishers lock in the color and build from the basecoats while relying on the acrylic-polyurethane waterborne topcoat for surface hardness and sheen control. The 20 gloss version provides a defined low-sheen target that fits projects where a modest, controlled reflection is desired across doors, panels, or trim. Because the product is part of a family with gloss levels at 10, 20, 40, and 90, finish shops can coordinate sheen expectations from specification through production and choose 20 gloss when that level best matches the design intent.
WB INTERIOR TOPCOAT 20 WHITE is positioned for interior finishing work that benefits from a 2K waterborne white topcoat over waterborne clear or pigmented basecoats. In multi-step coating systems, finishers can spray waterborne pigmented or clear basecoats to build color and film thickness, then apply this acrylic-polyurethane waterborne topcoat as the closing layer to establish final surface hardness and sheen. The 20 gloss level makes it suitable when design calls for a noticeably low-sheen but not fully matte finish, giving casework, millwork, or interior components a refined look without high reflectivity. Since the same product family offers 10, 40, and 90 gloss levels, finishing operations that handle a range of specifications can standardize on this chemistry and select 20 gloss specifically when a soft, uniform sheen is specified for interior applications.
The two catalyst options built into this system give finishers a choice between high performance with a shorter pot-life of 3 hours and an extended pot life of 8 hours, which directly affects how sessions are planned. On faster-moving jobs, the shorter 3-hour pot-life option supports tighter production cycles where mixed material is used quickly. On larger or more complex runs, the extended 8-hour pot life option lets crews keep material in use over a longer day, reducing interruptions from frequent remixes and helping maintain consistent film build and appearance across all pieces. The excellent surface hardness of this acrylic-polyurethane waterborne topcoat means that, once cured within the system, finished parts can handle typical interior handling and service demands. The ability to tint up to 4 percent by volume with XA2006/XX Waterborne Pastes supports precise color adjustment inside the waterborne system, which is useful when dialing in custom whites or matching existing interior finishes while still working within the same 2K waterborne white topcoat chemistry.
WB INTERIOR TOPCOAT 20 WHITE is a 2K waterborne white waterborne topcoat using an acrylic-polyurethane waterborne system, serving as the finishing layer in interior coating systems where this chemistry is specified.
The waterborne white interior topcoat is applied over waterborne clear or pigmented basecoats, so the basecoats set color and build while this layer provides final sheen and surface hardness for interior work.
The 20 gloss level provides a low-sheen finish, giving interior components a softer, less reflective look, which is useful when designs call for a subtle, uniform surface rather than a high-gloss appearance.
The two catalyst options allow choice between high performance with a shorter 3-hour pot-life and an extended 8-hour pot life, so working time can align with job size and production pace.
The acrylic polyurethane waterborne topcoat can be tinted up to 4 percent by volume with XA2006/XX Waterborne Pastes, enabling controlled adjustments to white or off-white shades within the system.
This ML Campbell waterborne topcoat family offers gloss levels of 10, 20, 40, and 90, so finishers can match specified sheen across projects while staying within the same coating chemistry.
WB INTERIOR TOPCOAT 20 WHITE, 25KG 2-PK gives finishing shops a 2K waterborne white topcoat that fits interior coating systems using waterborne clear or pigmented basecoats. Its acrylic-polyurethane waterborne formulation, excellent surface hardness, and defined 20 gloss level provide a consistent final film for interior work. With two catalyst options and tinting capability up to 4 percent by volume using XA2006/XX Waterborne Pastes, it supports both schedule-driven production and precise color control. Choose this ML Campbell waterborne topcoat when an interior 20 gloss finish is specified within a waterborne system.
