TotalBoat Silica Thickener is an extremely fine powder used to create a smooth, non-sagging, high-strength mixture for structural bonding, filleting, and filling. It can be used alone or in conjunction with Milled Glass Fibers or Phenolic or Glass Microballoons.
To prepare, first mix together the amount of resin/hardener that your project requires. Then add any fiber fillers or bulking agents and mix well. Add silica thickener to the mixture last. Remember to ALWAYS stir bottom to top.

To make polyester resin thick like peanut butter, I simply added 1 scoop of powder per ounce of resin. Mixing is quick and easy as it disappears into the mix becoming thicker as you stir. I used the thickened resin fill in the gaps around the backing plates for my chainplates and to also hold them in place while the holes were drilled. I also used it to thicken gelcoat to fix some scratches in the topsides. I thickened it the same way and then smeared it into the scratch instantly making the gouge disappear.

Worked as described. Was surprised to find out how much is needed to achieve the desired thickness. Ran through a quart really fast. Ordered another gallon and it's everything I needed. Wear a mask or respirator when using

Keeps drips and sags down vertical surfaces.

Easy, light, and applied with ease. I was expecting more texture in the hardened result, but smooth as it was laid. Great stuff!

Functions as it claims and easy to implement into a slow set epoxy.

I used this to repair the gel coat on my kayak. Received good advice from rep when I purchased the thickener. Results where great and predictable. Easy to work with.

I used the thickener to add body to the epoxy as instructed to fill holes from previous owners hardware position choices. After prepping and priming I now have integrity in areas that needed it.

Make sure you where a mask because this stuff is laughter than air but definitely a great product for making structural glue and fillets for glassing 👍
