## Features

- 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)
