Available in long and short virgin cellulose fibres from sustainable trees cultivation. BWW40 is a fine cellulose fibre powder used in papier mache, premix mortar sculpture and silicon rubber for vertical holding features in brush on application, moisture retention in cement curing, reduces shrinkage cracks and slumping, paper making with cellulose size, epoxy or polyester reinforcement instead of fibreglass, mix media art texturing of plaster, cement or clay, diorama as realistic artificial snow, ceramic bulking in weight reduction and porosities in firing as lightweight and other crafts. Its whiteness ensures color brilliance in painting. Art conservation use cellulose powder as fine fillers with dextrine starch binder cooked with Alum as preservative.
Safe organic fibres easy to use in mixing, kneading or blending with the appropriate medium by hand or mechanical mixing. Do note to avoid dust and fire hazard. Store in cool dark place and not in silo.
