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.

A 5-quart quantity of Silica Thickener when combined with 1 gallon kit of TotalBoat 5:1 epoxy (group size B), will produce about 1.75-gallons of smooth thixotropic epoxy filler
It works great as a fairing compound and makes sanding a lot easier.
Works great, makes very strong fillets, make it thick or thin. Light in color almost clear
Great product, poor packaging
First of all, Jamestown Distributors took care of me and for that I gave 3 stars. I took 2 stars off for having to go through the hassle of dealing with the following: I bought a 5 quart tub and when it was delivered, the lid had come off of the tub resulting in the filler spilling out all over inside of the box. Taping the lid down would have prevented this. In the past, I ordered a single quart and that was taped with strapping tape so why not this time? As for the filler, it mixes well with West Systems and does the job.To Jamestown Distributors: update your packing instructions for the order packers to always tape the tub lids.
Product opened and spilled during shipment ....caused me to breathe in when opening shipping container ... Otherwise product worked well.
I will by this product again
Making minor gel coat repairs is a snap with this filler.

This product worked as expected. It is very light and tends to blow around if there is any wind when it is mixed.
Total Boat Silica Thickener
Easy to use in our applications.
Thickener to make it stick
Added in sufficient amounts to thicken the TotalBoat epoxy so it would stay put against the underside of the deck long enough to insert the G10 reinforcement into the repair opening. Blended well once enough was added to get the right consistency.
