Talc Filler for Wood Putty and Primer
CAS Number: 14807-96-6
Micronized talc filler for wood putty, grain filler, and primer formulations provides excellent sandability, anti-settling, and surface smoothness. Its platelet morphology improves sag resistance and builds film thickness efficiently. Talc is the primary extender in NC and PU wood putty systems due to its softness, chemical inertness, and compatibility with all wood coating binders.
