WB INTERIOR TOPCOAT 40 CLEAR gives shops a 40 gloss interior finish built on a 2K waterborne clear waterborne topcoat system. This topcoat is an acrylic-polyurethane waterborne topcoat, so it delivers a waterborne workflow with a 2-component performance structure for interior projects. The product is designed to be applied over waterborne clear or pigmented basecoats in coating systems, allowing one topcoat to finish both clear and colored builds in the same line. Excellent surface hardness supports interior applications where a harder finished surface is desired. Good vertical hang and leveling support applications on vertical parts in a finishing rack. Two catalyst options provide flexibility between a high performance or extended pot life approach, so finishing teams can match the pot life window to the job size and pace.
This acrylic-polyurethane waterborne topcoat is built to be applied over waterborne clear or pigmented basecoats in coating systems, so process planning can center on a single topcoat product for both types of base layers. The 2K waterborne clear waterborne topcoat design uses two catalyst options, which directly affects pot life and scheduling. The high performance option pairs with a shorter pot-life of 3 hours, matching faster-moving interior lines or smaller batches. The extended pot life option reaches 8 hours, fitting longer spray sessions or larger runs where fewer mix breaks are preferred. Excellent surface hardness and good vertical hang and leveling tie directly into spray technique and rack layout because they support desired film build and visual results on interior workpieces.
WB INTERIOR TOPCOAT 40 CLEAR is a 2K waterborne clear waterborne topcoat positioned for interior coating systems that already use waterborne clear or pigmented basecoats. In these systems, the acrylic-polyurethane waterborne topcoat serves as the final film build layer over waterborne clear or pigmented basecoats, so it integrates as the top step in the coating stack. The 40 gloss version sits between the lower 10 and 20 gloss and the higher 90 gloss levels that are available for this line, so it targets interior applications where a mid-level sheen is specified. Because the same topcoat line offers gloss levels of 10, 20, 40, and 90, a shop can keep similar chemistry across different sheen targets while picking this specific product when a 40 gloss finish is required.
The two catalyst options on this acrylic-polyurethane waterborne topcoat directly control pot life choices, giving a finishing operation either a high performance and shorter pot-life window of 3 hours or an extended pot life of 8 hours. This range helps align mixing and spraying to interior project size and crew pace. Excellent surface hardness on the finished film supports interior scenarios where a harder surface is part of the performance expectation. Good vertical hang and leveling are important when coating doors, side panels, or trim pieces in a vertical position because they support film build without excessive movement while still leveling for appearance. The ability to be tinted up to 8 percent by volume with XA2006/XX waterborne pastes adds color-adjustment capability in the topcoat, which helps fine-tune tone or color depth in interior coating systems that use these waterborne pastes. A 40 gloss level gives a defined sheen target that sits within the broader gloss level range of 10, 20, 40, and 90 for this topcoat line.
