Features:
• Quick-drying
• Excellent grindability
• Closedness
• Water resistance
• When paired with MR1782W, it provides excellent resistance against springback in materials like rubberwood, black walnut, red oak, and pine.
• Can be paired with the AD7521 to enhance tannic acid sealing performance.
• Colorant Compatibility
• Compatible with both oil-based and water-based isocyanates, and the gun can be rinsed directly with tap water.
Applications:
• Water-based Wood Sealer Primer
Instructions for use:
• KDD®MR1783 can be directly diluted with alcohols or alcohol ether solvents. When used with a fatty isocyanate curing agent, it is recommended to thin with PMA or PM.
• When working with wood containing high levels of tannins, AD7521 can be added for a noticeable tannin-sealing effect.
