Magnasand Precat Sealer Clear, 53 Gallon - ML Campbell 0MC115049-27

Magnasand Precat Sealer Clear For Lacquer Systems

Magnasand Precat Sealer Clear is a water white HAPS free pre-catalyzed lacquer sealer, so it lays down a clear base that does not add color while keeping hazardous air pollutants out of the finishing step. This sealer is specified at 24 percent non-volatile by weight, which means each coat deposits a predictable build of solids that supports consistent film thickness from job to job. The product is described as a lacquer sealer with thermo set properties, so once cured it forms a crosslinked film that resists softening under later coats and regular use. Magnasand Precat Sealer Clear is used as a sealer for pre-catalyzed lacquers, tying directly into pre-cat lacquer topcoats for a compatible, unified system. The formula is also described as sanding easily, so leveled surfaces and defect touchups can be handled quickly between coats without fighting clogged abrasives.

Key Sealer Details That Support Finish Quality

• Water white color in this sealer keeps the film visually clear, which helps retain the original tone of the substrate and supports uniform appearance under compatible pre-catalyzed lacquers.
• Being HAPS free, this pre-catalyzed sealer avoids listed hazardous air pollutants, which matters where regulated air emissions or shop air quality considerations affect finishing choices.
• The 24 percent non-volatile by weight solids content provides a known amount of build in each coat, which helps target film thickness and schedule the number of passes required for a finishing system.
• Thermo set properties in the lacquer sealer create a crosslinking finish as it cures, which helps the sealed surface tolerate stacking, handling, and topcoats without the film printing or softening as easily.
• Magnasand Precat Sealer Clear is identified as a sealer for pre-catalyzed lacquers, which helps it integrate into pre-cat lacquer finishing workflows where product compatibility is important to performance.
• The description that it sands easily means abrasives cut cleanly across the film, which supports faster leveling, smoother surfaces, and reduced time spent on re-sanding between finish steps.
• Fast drying behavior in this ML Campbell sealer shortens the window between application and sanding or recoating, which can compress booth time and help move projects through the finishing department efficiently.

Application Behavior, Drying, And Sanding Workflow

This ML Campbell Magnasand sealer is described as fast drying, so the coated surface reaches a workable state quickly and supports tighter intervals between application, sanding, and topcoat. The water white description indicates the applied film stays clear, which helps when targeting natural or lightly toned finishes and when checking coverage during spraying. Because the product is a pre-catalyzed lacquer sealer with thermo set properties, it is designed to cure into a more fully crosslinked layer, supporting later coats of compatible pre-catalyzed lacquer without re-melting the base. The statement that Magna br Sand Sealer sands easily means technicians can level dust nibs and overspray quickly, which keeps abrasive consumption and touchup time under control while preparing for subsequent coats.

Using This Sealer In Pre Catalyzed Lacquer Systems

Where This ML Campbell Magnasand Sealer Fits

Magnasand Precat Sealer Clear is described as a lacquer sealer used as a sealer for pre-catalyzed lacquers, so it fits into finishing systems that build with pre-cat lacquer topcoats. As a water white product, it suits applications where a clear, non-yellowing base is desired beneath compatible pre-catalyzed lacquer, such as clear-finished work that depends on the substrate color for final appearance. The sealer is in the sealers class within solvents, stains, and finishes, which places it in the film-building step between staining or bare wood preparation and subsequent lacquer coats. With fast drying behavior, this product supports production workflows where multiple coats of pre-catalyzed lacquer are scheduled in a single shift on the same parts.

Why Thermo Set And Sanding Traits Matter

The product description notes thermo set properties, meaning the cured sealer film crosslinks rather than staying thermoplastic, which helps it hold its integrity when additional pre-catalyzed lacquer coats are applied over it. This crosslinked behavior supports resistance to print-through under stacking or handling after the system is built. The 24 percent non-volatile by weight content gives a measurable solids deposit per coat, which helps balance sealer build with topcoat build so the combined film does not become excessive while still providing coverage. Because Magnasand Precat Sealer Clear sands easily, technicians can flatten raised grain and overspray without aggressive cutting, helping retain that planned film build. Its fast drying characteristic further ties into sanding and recoating, since quicker through-dry times enable a steady progression from sealer to multiple pre-catalyzed lacquer coats within standard production windows.
