Q-Cel 300, lightweight filler, hollow inorganic microspheres with exceptional whiteness and low bulk density. The primary function of this filler is to reduce resin usage, but Q-Cel can also reduce density Q-Cel products reduce density, improve processing and flow, increase filler loading, reduce shrinkage, improves sand ability and machining qualities, offers sound thermal insulation while reducing cost per part by replacing expensive resin.

Suited for many applications, including fiberglass reinforced plastics, urethane foams, putties, cultured marble and adhesives. The addition of hollow spheres to fiberglass reinforced plastics (FRP), epoxy, compounds, and urethane castings can provide weight reduction cost savings and improved impact resistance. Insulating features of hollow spheres also work to the chemists’ advantage in thermal shock and heat transfer areas.

• Q-Cel Filler is used to thicken Polyester and Epoxy resin to create a “Foam White” fill paste that is easy to sand. When added to polyester or epoxy resin, Q-Cel filler thickens the resin to make it more workable and expands it to fill in large areas and reduce the overall weight, especially in applications where a light weight is of primary importance.
• Q-Cel Filler. is an exceptionally fine powder which is great for bulking out fillers for larger dings, effective replacement for foam and cures to a white finish.
• Q-Cel provides an economical way of extending resin by reducing the amount of resin required
• Q-Cell is added to resin at the rate of 5% -10% by weight dependent upon application, and up to 20% can be added if a paste consistency is required. Q-Cell is only a filler and should be sealed with a layer of cloth or fiberglass.
• MADE IN THE USA and is great for boats, fiberglass, and surfboard repairs (packed in Quart container - 6oz)
