NY Flattening Paste Post/Pre Cat Gallon is a non-yellowing flattening paste designed for use in M.L. Campbell post-catalyzed, pre-catalyzed, nitrocellulose, and some Euro topcoats, so you can control sheen across multiple finish systems with one product. The paste is described as very efficient, which helps you reach target gloss levels with lower addition rates and more predictable results. This HAPS free formula eliminates Hazardous Air Pollutants from the paste itself, supporting shop environments that need to limit these solvents during finishing operations. The flattening paste is also formaldehyde free, which matters anywhere reduced formaldehyde content is part of job or facility requirements. Non-Yellowing Flattening Paste has easy stir in properties, so it disperses into the lacquer quickly and supports consistent sheen across large jobs. The product also has soft settling properties, so material in the container can be re-suspended with less mixing time between uses.
The manufacturer recommends adding Non-Yellowing Flattening Paste before tinting and or/catalyzing, which lets the paste integrate into the lacquer base so later tint or catalyst additions work into a uniform mixture. Stir the flattening paste into the lacquer until well dispersed, which supports even gloss reduction across sprayed surfaces. For best results, the product is recommended for use in the finish coat, which focuses the gloss adjustment where it most directly affects the final appearance. The instructions note that it is not recommended that you drop sheen more than 1 sheen level, for example gloss to dull, which guides how aggressively to target sheen changes. The product reference to the M.L. Campbell Gloss Reduction Chart for required percentages provides a defined starting point for selecting addition levels that align with the desired gloss step.
Non-Yellowing Flattening Paste is specified for use in M.L. Campbell post-catalyzed topcoats, so cabinet and millwork shops using these systems can integrate gloss control into existing finishing lines. The paste is also specified for M.L. Campbell pre-catalyzed topcoats, which allows a single gloss reduction approach across both post-cat and pre-cat lacquers in the same shop. The product is suitable for nitrocellulose topcoats, giving finishers a way to dial back sheen on traditional nitro systems while using the same flattening material. It is also suitable for some Euro topcoats, which lets finish operations that use certain European-style systems bring gloss levels in line with project expectations using one paste across compatible lines.
The recommendation to add the flattening paste before tinting and or/catalyzing shapes the workflow so the paste becomes part of the base mix, supporting even color and cure in the final film. Stirring Non-Yellowing Flattening Paste into the lacquer until well dispersed helps avoid localized low-sheen or high-sheen areas, which matters on doors, panels, and long runs. Using the paste in the finish coat focuses gloss reduction where it has the greatest visual impact, so intermediate coats can remain at standard formulation while the final pass sets the sheen. The statement that it is not recommended that you drop sheen more than 1 sheen level, such as gloss to dull, defines a practical operating window that supports predictable leveling, clarity, and appearance. Referring to the M.L. Campbell Gloss Reduction Chart for required percentages ties the process to known addition ranges, helping shops repeat chosen gloss levels across batches and projects.
NY Flattening Paste Post/Pre Cat Gallon is a non-yellowing flattening paste for M.L. Campbell post-catalyzed, pre-catalyzed, nitrocellulose, and some Euro topcoats, so it is used to reduce sheen in these finish systems.
Non-Yellowing Flattening Paste is for use in M.L. Campbell post-catalyzed, pre-catalyzed, nitrocellulose, and some Euro topcoats, so it supports sheen control across those specified finishes.
Non-Yellowing Flattening Paste is recommended to be added before tinting and or/catalyzing and stirred into the lacquer until well dispersed, which supports even gloss reduction in the applied film.
Non-Yellowing Flattening Paste is recommended for use in the finish coat, so the final applied layer sets the visible sheen level on the completed work.
With this flattening paste it is not recommended that you drop sheen more than 1 sheen level, such as gloss to dull, which keeps gloss reduction within the suggested range.
The non-yellowing flattening paste helps maintain the original color tone of post-catalyzed, pre-catalyzed, nitrocellulose, and some Euro topcoats, which is important on light finishes and clear systems.
NY Flattening Paste Post/Pre Cat Gallon from M.L. Campbell provides non-yellowing, HAPS free, formaldehyde free gloss reduction specifically for post-catalyzed, pre-catalyzed, nitrocellulose, and some Euro topcoats, giving finishers a defined method to tune sheen. Its easy stir in and soft settling behavior support consistent results through the entire container, while the guidance on adding before tinting and or/catalyzing helps structure the finishing workflow. The recommendation to use this efficient paste mainly in the finish coat and within a one-level sheen drop, supported by the M.L. Campbell Gloss Reduction Chart, provides a clear framework for achieving repeatable, project-ready gloss levels.
