POLARION 2K Polyurethane Clear Gloss 5G is an ML Campbell two component acrylic polyurethane interior clear topcoat that provides an extremely durable finish, so cabinet and millwork surfaces stand up to demanding use in woodworking environments. Its GREENGUARD Certified status identifies it as suitable for interior applications where indoor air quality is important on finished woodwork. The high build and clarity of this clear gloss system create a substantial film that still lets the natural character of the substrate show, supporting projects where appearance and protection both matter. Because this product is classified as a clear topcoat, it serves as the final protective layer over properly prepared interior surfaces, streamlining finishing schedules. As part of the Polarion line, it complements professional finishing systems focused on consistent, repeatable results across multiple jobs.
This Polarion interior clear uses a 5:1 catalyst mix ratio, providing a defined proportion that supports consistent film performance from batch to batch during finishing runs. The extended pot life noted for the system keeps mixed material usable for a longer working window, which is valuable on larger jobs or production lines that require steady throughput. Because no solvent reduction is required based on spray conditions, the product can be sprayed as supplied once catalyzed, simplifying viscosity management during setup and helping maintain the intended solids level in the applied film. These characteristics together support a predictable spray workflow in professional shops and serious DIY finishing spaces.
Polarion 2K polyurethane interior clear functions as a clear topcoat within ML Campbell finishes, so it is suited to interior wood components where a protective final film is required over compatible base systems. Its classification in clear topcoats places it in applications such as cabinetry, furniture, millwork, and interior fixtures where a transparent protective layer is needed. The excellent sanding characteristics described for this product support intercoat abrasion between applications, which helps level the film and refine the surface before subsequent coats. Its strong polishing characteristics allow finishing teams to refine the gloss level and surface smoothness after curing, which can be valuable on high-visibility panels, tabletops, or reception elements. Because the product offers high build with clarity, it can form an even film on flat panels and profiled parts while preserving substrate detail, aligning with projects that demand both protection and a clean visual presentation.
The non-yellowing acrylic polyurethane technology used in Polarion interior clear maintains finish color over time, which supports multi-part installations where matching between doors, frames, and trim is important long after the initial job. Superior scratch, mar, chemical, and moisture resistance contribute to finish stability during handling, transport, and everyday interior use, which helps protect invested labor on complex assemblies. High solids that aid coating edge retention help keep coverage uniform at corners and edges, reducing thin spots that can otherwise wear faster in service. Extended pot life gives more working time from each catalyzed batch, which supports uninterrupted production on spray lines or in batch finishing setups. Because no solvent reduction is required based on spray conditions, the applied material maintains its intended solids, reinforcing build, edge coverage, and overall film performance in repeat production runs.

The GREENGUARD Certified status identifies Polarion interior clear as suitable for interior environments focused on indoor air quality, supporting its use on cabinets, furniture, and millwork in occupied spaces.
The 5:1 catalyst mix ratio provides a clear proportion for combining components, which supports consistent curing and film performance across multiple batches during production work.
The extended pot life of Polarion interior clear keeps catalyzed material usable longer, allowing larger runs or complex layouts to be sprayed without frequent mixing interruptions.
The high build and clarity of Polarion 2K polyurethane allow a substantial protective film while keeping the substrate visible, supporting attractive finishes on detailed woodwork.
The excellent sanding and polishing characteristics help level the film between coats and refine gloss after curing, contributing to a smooth, professional surface on finished pieces.
Polarion 2K polyurethane interior clear from ML Campbell combines a two component acrylic polyurethane structure, GREENGUARD Certification, and non-yellowing technology to support durable interior wood finishes. Superior scratch, mar, chemical, and moisture resistance protect cabinets, furniture, and millwork in active spaces. High solids with strong edge retention help maintain consistent film build on profiles and corners, while excellent sanding and polishing characteristics simplify achieving a refined gloss. With a defined 5:1 catalyst mix ratio, extended pot life, and spray-ready use without solvent reduction, this clear gloss topcoat fits production-focused and detail-oriented finishing operations. Apply it as the interior clear topcoat when a high build, transparent film and long-term appearance are priorities.
