Fiberglass chopped strands.

 5 lbs  $19.95

For Epoxy or Polyester resins

1/4 inch in length

In simple laymen’s terms, adding chopped strands to epoxy or polyester resin is like adding re-bar to concrete.

The chopped strands act to make the resin stronger.

Chopped strands increase mechanical strength, and increase the tensile strength impact resistance, and compressive and flexural strength.

They improve dimensional stability, and minimize distortion at elevated temperatures.

Chopped strands can be used to increase the ability of fiberglass resins to bridge gaps.

They should be added where increased strength is needed for bonding, filleting, and fastening with resin.

To use:

- mix your resin and hardener, or catalyst

- next add your chopped strands

- it is best to use a paint mixer on your power drill to ensure that all of the strands are properly saturated.

Thick layers and large pour areas can create excessive heat, so proceed with caution.

    I used this to thicken the epoxy when filling small drill holes after they've been ground out a bit.
