Where to use TotalBoat fillers

Milled glass fibers are commonly used when epoxy must fill a void, provide high strength, and high resistance to cracking. Examples include structural filleting, bonding hardware, and keel bedding. TotalBoat fillers can be used with either epoxy or polyester resins to change the resin properties for various uses, such as bulking out the resin or making it easy to sand. Because fillers can affect the pot life of a resin, create a small trial batch first to determine how much working time you’ll have.

Frequently Asked Questions

What are Milled Glass Fibers used with epoxy for?

Milled glass fibers are used in epoxy systems to increase tensile strength and flexibility, and it’s formulated to help reduce shrinkage. It’s ideal for use in situations where you must fill a void because it’s very high strength and provides resistance to cracking. Examples include structural filleting, bonding hardware, and keel bedding.

Which epoxy system should you use with Milled Fibers?

You can use both 2:1 and 5:1 epoxy resin systems with Milled Fibers.

Can you mix Milled Glass Fibers with other fillers?

Yes, you can blend Milled Glass Fiber and other fillers into a mixed resin/hardener.

Why would you combine Milled Fibers with Silica Thickener?

Combining milled fibers with Silica Thickener will strengthen the resin to prevent sagging and draining on vertical and overhead surfaces.

Can you use Milled Fibers with polyester or vinyl ester resin?

Milled Glass Fibers are chemical-resistant, so they are often used with both polyester and vinyl ester resin in putty form for deep blister repair on boats.

How much should you add to epoxy?

Add 5% of Milled Glass Fibers by weight to the epoxy after it has been catalyzed to increase the tensile strength without negatively affecting pourability.
