3Ms “Best” for Sanding Wood by Hand
“Best” among our abrasive sheets for sanding woods of all types, the 3M Paper Sheet 435U features a silicon carbide mineral in three grades. Silicon carbide is a synthetic mineral that is very sharp and commonly used for final finishing in white wood sanding.
Silicon carbide abrasive sheets create a smoother finish than aluminum oxide abrasive products on wood as well as composite and advanced material substrates. Its resin bond construction provides superior grain retention while the open coat construction, along with the load resistant coating, combine to provide excellent anti-loading characteristics. Abrasive mineral stays clean and cutting, extending abrasive life.
Durable and Useful
Its 100, 120 and 150-grade mineral is resin-bonded to a durable C-weight paper backing. It resists tearing and stands up to rigorous applications. Standard 9 x 11-inch sheets are easily resized for a multitude of tasks. Whether youre working with hardwoods, softwoods, or with composites or advanced materials, this sheet performs.
Recommended Applications
The 3M Paper Sheet 435U is ideal for whitewood hand sanding, in particular. Use it with our 3M Sanding Block (sold separately).
