        			These bulking agents are hollow, clear microscopic spheres that make a low cost, low density filler. Added to epoxy resin and hardener mix, they make a good, heat-resistant, light-weight fairing compound with good compressive strength. Mixture can be blended with a small amount of Silica Thickener to prevent sagging. Not recommended for glue. Alternatively use SilverTip QuikFair for ease-of-use.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for making sandable filler
*by J***Y on September 5, 2017*

These simply work great for making a sandable "filler". I've used these both with just epoxy itself and with epoxy + fumed silica where I need a thicker "putty" for vertical surfaces. As stated on the bucket these should not be used to make "glue"!

### ⭐⭐⭐⭐⭐ Five Stars

### ⭐⭐⭐⭐⭐ Ideal for mixing with Marine epoxy
*by J***B on March 31, 2016*

Ideal for adjusdting viscosity in different applications of marine epoxy. It also helps save epoxy.Hotsmart keep-hot bowl
