406 Colloidal Silica is a thickening additive used to
control the viscosity of epoxy and prevent epoxy
runoff in vertical and overhead joints. 406 is a
very strong filler that creates a smooth mixture,
ideal for general bonding and filleting. It is also our most versatile filler. Often used in combination with other fillers, it can be used to improve strength, abrasion resistance, and consistency of fairing compounds, resulting in a tougher, smoother surface. Color: Off-White.
FILLERS AND ADDITIVES
      Our “workhorse" filler, 403 Microfibers, is
made of fine cotton fibers and is used as a
thickening additive with resin/hardener to
create a multi-purpose adhesive. Microfibers
and epoxy are particularly effective in bond-
ing wood. Epoxy thickened with microfi-
bers provides good gap-filling qualities while
retaining excellent wetting and penetration
capabilities. Microfibers are used primarily in
bonding and gap-filling applications. Microfibers are non-toxic, but care should be taken to avoid inhalation. Color: Off-White.

404 High-Density filler is a thickening addi-
tive developed for maximum physical prop-
erties in hardware bonding where high-cy-
clic loads are anticipated. It can also be used
for filleting and gap-filling where maximum
strength is necessary. May be added to the
resin/hardener at a rate of 20 to 30% by weight, depending on the viscosity needed. Color: Off-White.

405 Filleting Blend is a strong, wood-toned filler for
use in glue joints and fillets on naturally-finished
wooden interiors. Mixes easily with epoxy and lets you
create fillets that are smooth and require little sanding.
Color is a consistent tan so it can be used to modify the shade of other West System fillers.
407 Low-Density filler is a blended Microballoon-
based filler used primarily to make inexpensive
filling and fairing putties which are easy to sand
or carve while still being a reasonably good engi-
neering material on a strength-to-weight basis. It
can also be used as a thickening additive for bonding veneers and in low-stress structural applications where light weight can be beneficial. Good feathering and won’t sag. Color: Reddish-Brown.

greater ease than 407 or Microballoons, and is approximately 30% easier to sand. It is also more economical for large fairing jobs but is not recommended under dark paint or other surfaces subject- ed to high temperatures. Cures to a light tan color. Do not mix 410 MICROLIGHTTM filler with polyester or vinylester resins. Microlight will inhibit the cure of polyester or vinylester resins.

 Various fillers can be combined to achieve desired working properties.
ALWAYS MIX RESIN & HARDENERS FIRST
BEFORE ADDING FILLERS AND ADDITIVES
For superior holding strength it is always best to “Wet Out"the sub- strate with your resin/hardener mixture before adding any filler.
