Polyklear Microspheres are very small, hollow glass spheres primarily used to reduce density to make an item lightweight. It adds impact strength, promotes easier sanding and produces a product that can be nailed or screwed with less chance of cracking. It is added to resin at 50-150 phr, depending on the desired consistency. Sanding of microsphere-filled resin products will make items porous, thus are not recommended to be done for applications requiring constant water contact.
