We stock the full line of fillers and additives to the West System® line. The fillers are used to thicken the epoxy mix to allow for filling, fairing, bonding hardware, gap-filling, and smooth surface epoxy applications. The additives are used to increase the abrasion resistance, UV stability, friction, and moisture resistance of the adhesive.
