WB INTERIOR TOPCOAT 90 CLEAR is a 2K waterborne clear waterborne topcoat that finishes interior projects with a clear acrylic-polyurethane film, so woodwork keeps its natural look while gaining a functional coating in one product system. This acrylic-polyurethane waterborne topcoat is designed to be applied over waterborne clear or pigmented basecoats in coating systems, which simplifies product selection when you are standardizing on waterborne technology across a finishing shop. The 90 gloss level is one of several gloss levels available at 10, 20, 40, and 90, so this specific version delivers a high-gloss appearance within a coordinated gloss range for different projects. The product is listed as WB INTERIOR TOPCOAT 90 CLEAR,6L 2-PK with manufacturer part number AT488500D-63, which helps align ordering and finishing specs on job documents.
This acrylic-polyurethane waterborne topcoat is intended to be applied over waterborne clear basecoats, which lets clear systems stay within one waterborne technology family from sealer to topcoat. The product is also specified for use over waterborne pigmented basecoats in coating systems, allowing the same topcoat to be used across both clear and pigmented interior jobs. The two catalyst options are defined as a high performance choice with a shorter pot-life of 3 hours and an extended pot life choice of 8 hours, so application timing can be selected around booth capacity or part complexity. The topcoat offers good vertical hang and leveling, so it supports application on cabinet doors, panels, or trim where runs and poor flow would otherwise create rework.
This 2K waterborne clear waterborne topcoat is designed for interior finishing where a clear acrylic-polyurethane waterborne topcoat completes a multi-coat system. The product is described for use over waterborne clear basecoats, so it fits well into clear interior systems where waterborne sealers have already been applied to the substrate. It is also intended for use over waterborne pigmented basecoats in coating systems, which means the same material can be specified whether the job calls for clear wood appearance or solid-color finishes on cabinets or fixtures. The excellent surface hardness supports applications on components that will experience regular handling, because the cured film is described as resisting marking at the surface during normal interior service. Good vertical hang and leveling support production on vertical parts where finishing teams need films that resist sag while still flowing to a smooth appearance as they dry.
The topcoat offers two catalyst options described as providing flexibility, with one option noted as high performance with a shorter pot-life of 3 hours, which supports fast-turn jobs where material will be used promptly after mixing. The extended pot life option with 8 hours lets a mixed batch stay in use longer, which helps when part volume is high or spray windows are spread across a shift. The ability to tint the product up to 8 percent by volume with XA2006/XX Waterborne Pastes allows shops to introduce controlled color or tone adjustments in the topcoat layer while staying within the stated tinting window. The clarification that AT48 is not a convertor base defines its role in the system as a ready-to-tint topcoat rather than a base that must be converted, which streamlines product selection when designing finishing schedules. The available gloss levels of 10, 20, 40, and 90 give finishing operations a defined gloss ladder, so projects can specify anything from low-sheen to high-gloss while staying within the same product family.

WB INTERIOR TOPCOAT 90 CLEAR is described for application over waterborne clear or pigmented basecoats in coating systems, so it functions as the final waterborne layer over compatible interior basecoat steps.
The topcoat is noted for excellent surface hardness, which means the cured film resists surface marking during interior service, helping finished parts keep their appearance in regular use.
Good vertical hang and leveling mean the topcoat resists sags on vertical pieces while flowing to a smooth surface, which supports consistent finishes on doors, panels, and trim.
The product offers two catalyst options: a high performance choice with a shorter pot-life of 3 hours, and an extended pot life option of 8 hours, so material usage can match job timing.
WB INTERIOR TOPCOAT 90 CLEAR can be tinted up to 8 percent by volume with XA2006/XX Waterborne Pastes, which allows controlled color adjustment within the stated tint limit.

Its excellent surface hardness, good vertical hang and leveling, and two defined catalyst options with 3-hour or 8-hour pot-life support planning around part volume and booth time. Tintability up to 8 percent with XA2006/XX Waterborne Pastes and available gloss levels of 10, 20, 40, and 90 position this ML Campbell product to handle a range of interior clear and pigmented finishing specifications.
