WB INTERIOR TOPCOAT 20 CLEAR identifies this ML Campbell 2K Waterborne Clear Waterborne Topcoat as the 20 gloss version, which defines the sheen level the finished surface will show and helps target projects needing that specific appearance. This product is described as an acrylic-polyurethane waterborne topcoat, so it forms a film based on acrylic and polyurethane chemistry that supports interior finishing where a waterborne system is required. The topcoat can be applied over waterborne clear or pigmented basecoats in coating systems, creating a unified system that keeps products within the same waterborne family and supports consistent performance from base to finish. Being a clear waterborne topcoat, it preserves the underlying color from the basecoat while providing the final protective layer that completes the coating system.
The 2K Waterborne Clear Waterborne Topcoat can be applied over waterborne clear or pigmented basecoats in coating systems, so it fits into waterborne finishing lines where primers and surfacers are already water-based. Being acrylic-polyurethane, the topcoat provides a film that complements waterborne basecoats, helping maintain system compatibility from first coat to final finish. The product is identified as an interior topcoat, focusing its use on interior environments where waterborne technology is preferred as part of the overall coating workflow. Because the topcoat is clear and designed for use over basecoats, it acts as the final layer that locks in the color or stain work established earlier in the system.
The Web Description states that this is a 2K Waterborne Clear Waterborne Topcoat that can be applied over waterborne clear or pigmented basecoats in coating systems, so it is positioned for interior finishing lines that already rely on waterborne primers and color coats. The Category lists Clear Topcoats and Product Class lists Topcoats, identifying it specifically as the finishing layer in multi-coat systems rather than a sealer or base. The product is identified as an interior topcoat, so its role is to provide the final clear film on interior projects where waterborne chemistry is required across all coats. Because the system supports both clear and pigmented basecoats, it can serve in programs ranging from natural-look clear work to fully opaque color finishes on interior components.
The description notes Excellent Surface Hardness, so once cured the film stands up better to routine contact and handling, which supports interior components that are regularly touched in service. Good Vertical hang & leveling means the topcoat resists runs while still flowing out, helping sprayed vertical work such as cabinet doors achieve a more uniform film with less rework from sagging. Two catalyst options for flexibility are specified, so finish shops can align catalyst selection with their workflow needs while staying within the defined system. The High Performance / Shorter Pot-Life (3 hours) option supports runs where fast cycling is important, while the Extended Pot Life (8 hours) option supports longer working sessions from a single mix. The product can be tinted up to 8% by volume with XA2006/XX Waterborne Pastes, so finishers can introduce color directly into the topcoat layer when a tinted clear film is part of the system design, keeping all components within the same waterborne family.
