Description
3M(TM) Paper Sheet 426U is a
general purpose abrasive
sanding sheet constructed on
an A-weight, light paper
backing and features an
anti-loading coating and open
coat construction. Silicon
carbide abrasive and
lightweight paper backing
make this sheet an ideal
product for finishing
applications such as paint
prep, white wood sanding,
sealer sanding, and solid
surface finishing.
Our silicon carbide abrasive
sheets create a smoother
finish than aluminum oxide or
garnet abrasive products on
painted metal and wood
substrates. Its resin bond
construction provides
superior grain retention
while the open coat
construction, along with the
load resistant coating,
combine to provide excellent
antiloading characteristics.
The light A-weight backing
provides conformability over
contours and into crevasses
and corners. The sheet can
also be easily cut to fit a
hand pad block, inline
sanders, or finishing or
power sanders. Other
applications include general
sanding, finishing, blending,
surface leveling and prep
prior to staining or
painting. These versatile
sanding sheets contain the
ideal abrasive grain type and
grades for multi-step
finishing processes.
Silicon carbide is a
synthetic mineral that is
very sharp and commonly used
for final finishing in white
wood sanding. While it breaks
down faster than aluminum
oxide, it produces a superior
finish.
