Description
Interlux Flattening Agent for 1-Part Polyurethane – Quart (INT-YMA715-QT)
Achieve a satin or matte finish with your Interlux 1-part polyurethane topcoat using this genuine Interlux Flattening Agent. Designed specifically for use with Interlux 1-part polyurethane paints such as Toplac and Brightside, this additive reduces the gloss level of the cured film without compromising durability, adhesion, or UV resistance. Ideal for topsides, superstructures, and interior surfaces where a lower sheen is preferred for aesthetics or to reduce glare.
Key Features
- Specifically formulated for Interlux 1-part polyurethane topcoats (Toplac, Brightside, and compatible products)
- Reduces gloss level from high-gloss to satin or matte finish depending on addition rate
- Does not compromise the durability, flexibility, or UV resistance of the topcoat
- Easy to mix — add to paint and stir thoroughly before application
- Quart (946 mL) size — sufficient for multiple batches across a full topside repaint
- Consistent, repeatable results when mixed at the recommended ratio
Usage Notes
Add the flattening agent to the paint at the recommended ratio (consult the Interlux product data sheet for your specific topcoat). Mix thoroughly before application. The more flattening agent added, the lower the final sheen. Always test on a small area first to confirm the desired finish level before full application. Not for use with 2-part polyurethane systems.
