The heat activated composite material, which contains its own
adhesive, is often referred to as the “Celastic” replacement
product. This pliable, scrim-reinforced extruded composite is a
revolutionary new material, with a smooth surface on one
side that can be molded or formed once it’s been heated. Easily
painted or decorated with a variety of artisan coatings, gessos,
bondo and paints. It has superior strength and flexibility, yet
is remarkably lightweight. You’ll find it fabulous for
headpieces, sub-structures, ornamental effects, masks, props,
scenic materials and a whole lot more.
Because it’s so tough and can be molded into any shape or
thickness, it’s even ideal for making quick repairs or
modifications. An oven, microwave, hot air gun or simply hot
water may be used for activation. With a low activation
temperature of 150°-170° F (70° – 80° C, Wonderflex® has a long
open time and can be hand-worked or laid up for two or three
minutes. Just reheat repeatedly as required for additional
forming. It works beautifully with or without molds and cuts
with a utility knife or scissors. It bonds to itself well and
can be adhered to most porous materials like paper,
wood, fabric, foams and Fosshape®.
