Polarion 2K Polyurethane Interior Clear is an extremely durable two component acrylic polyurethane, so it builds a tough film that stands up to demanding interior use. This interior clear is GREENGUARD Certified, which supports projects where low-emission finishes matter for occupied spaces. The product offers exceptional high build and clarity, allowing you to create a smooth film while still showing the character of the substrate. Its true non-yellowing performance maintains the original look of light colors over time. A full range of sheens is available within the system, so this clear integrates easily into different design standards while keeping the same resin technology on the job.
This Polarion interior clear is designed as a clear topcoat within ML Campbell's Polarion system, so it functions as the finishing layer over prepared substrates in interior work. The exceptional high build allows you to reach target film thickness in fewer coats compared to leaner systems, which is useful when running larger batches through a finishing line. Because the coating sands and polishes excellently, it supports refined surface preparation between coats and post-finish rub-out work where a higher-end appearance is required.
Polarion Interior Clear is an acrylic polyurethane topcoat intended for interior use, so it fits projects where a clear, durable film is needed over stains or natural wood tones. Its exceptional clarity helps maintain grain definition and color accuracy on doors, casework, and trim, which is important when matching architect-specified finishes. The non-yellowing performance means light-colored designs stay closer to their original appearance under normal interior exposure. Because this product is GREENGUARD Certified, it suits interior environments where emissions criteria are part of the project requirements, aligning the finish choice with those standards.
High solids in this clear topcoat contribute to strong edge retention, which can reduce thin spots on profiles and minimize rework on routed components. Superior scratch and mar resistance helps finished parts move through handling, transport, and installation with fewer visible surface marks. Excellent chemical and moisture resistance supports long-term appearance when the finish encounters typical cleaners or incidental moisture during service. The extended pot life provides a practical window for spraying without frequent waste of catalyzed material, supporting consistent film appearance across multiple parts. A defined 5:1 catalyst mix ratio, with no solvent reduction required based on spray conditions, streamlines mixing and application, which helps keep finish results consistent from batch to batch.
Polarion 2K Polyurethane Interior Clear is a two component acrylic polyurethane, so it cures to a durable film suitable for interior clear topcoat applications.
The non-yellowing acrylic polyurethane technology helps light-colored finishes and clear systems maintain their original appearance over time in interior settings.
Polarion Interior Clear is GREENGUARD Certified, so it supports projects that require finishes meeting specific indoor air quality and emissions criteria.
The 5:1 catalyst mix ratio specifies the proportion of base to catalyst, helping achieve consistent curing and film properties from one mixed batch to the next.
The high solids content aids in coating edge retention and overall build, allowing target film thickness with fewer coats and better coverage on detailed profiles.
The extended pot life keeps catalyzed material usable longer, which supports steady spray work on larger runs without frequent mixing interruptions.
Choose Polarion 2K Polyurethane Interior Clear when an interior clear topcoat must combine high build, clarity, and non-yellowing performance under one system. Its GREENGUARD Certification, superior scratch, mar, chemical, and moisture resistance, and practical 5:1 catalyst mix ratio align well with production-focused finishing work. Using this ML Campbell Polarion clear topcoat helps maintain consistent film quality and appearance across interior components that see regular use.
