Polarion 2K Polyurethane Interior Clear is an extremely durable, two component acrylic polyurethane designed as an interior clear topcoat, so it builds a strong protective film that helps finished work hold up under regular use in woodworking and cabinet environments. This interior clear is GREENGUARD Certified, which supports use in projects where low-emitting coatings are important for occupied interior spaces. The finish offers exceptional high build and clarity, allowing film thickness to build quickly while keeping the natural appearance of the substrate visible. It delivers excellent chemical and mar resistance, so the cured surface stands up to routine contact with household chemicals and handling in service. The product also provides true non-yellowing performance, which maintains the original tone of the underlying color system over time on interior jobs. A full range of sheens in the Polarion Interior Clear system offers flexibility for appearance targets across different projects.
This Polarion 2K Polyurethane Interior Clear uses a 5:1 catalyst mix ratio, so finishers can follow a straightforward two component mixing step before application. The system offers extended pot life, which allows mixed material to remain usable for a longer window during a shift, supporting larger runs and reducing interruptions to remix. No solvent reduction is required based on spray conditions, so the product can be sprayed at the supplied solids level when conditions align with the manufacturer guidance, which simplifies setup of the coating step. The coating has high solids that aid in coating edge retention, meaning film build along edges is better supported as the product cures, which is useful on doors, cabinet parts, and milled profiles. Polarion Interior Clear also has excellent sanding and polishing characteristics, so between-coat work and final rub-out steps are easier to control to achieve the targeted sheen and smoothness.
Polarion 2K Polyurethane Interior Clear is positioned within ML Campbell clear topcoats for interior use, so it fits wood finishing and cabinetry work where a clear, protective film is required. As a product in the Solvents, Stains & Finishes category under Clear Topcoats, it serves as a finishing layer over properly prepared interior substrates in woodworking shops. The acrylic polyurethane technology provides non-yellowing performance, which is valuable on light-colored woods, whites, and contemporary finishes where color shift would conflict with design intent. Exceptional high build allows film thickness to develop with fewer coats compared to lower-solids systems, which can shorten the path to a uniform surface across doors, face frames, and panels. Because the product offers a full range of sheens within the Polarion Interior Clear line, finishers can standardize on one technology while meeting varied sheen specifications for different rooms or customer preferences in a single project or across multiple jobs.
The high solids content in Polarion 2K Polyurethane Interior Clear aids in coating edge retention, so edges on doors, shelves, and trim are less prone to appearing thin compared to flat areas after curing. This characteristic supports more uniform film build around profiles, which improves overall appearance on detailed millwork. Excellent chemical and moisture resistance helps the finish tolerate exposure to moisture and household chemicals in typical interior use, which supports long-term serviceability in kitchens, baths, and workspaces where contact with liquids and cleaners is common. Superior scratch and mar resistance reduces visible handling marks during fabrication, installation, and ongoing use, helping finished surfaces stay presentable in service. The extended pot life of the mixed two component system gives shops freedom to run larger batches of parts without frequent interruptions to prepare fresh material, which can improve throughput. GREENGUARD Certification adds value in projects where low-emitting materials are specified for interior spaces, helping the coating align with documented emission criteria.
