## Overview

West System 206-B Slow Hardener is a low-viscosity epoxy curing agent designed to pair with 105 Resin at a precise 5:1 ratio, offering extended working time and high-strength, moisture-resistant bonds. Ideal for professional-grade coatings, structural bonding, and customized applications with fillers and pigments, it enables flawless finishes and durable repairs for demanding projects.

## Description

206 Slow Hardener is a low-viscosity epoxy curing agent for use with WEST SYSTEM 105 Resin when extended working and cure time is needed or to provide adequate working time at higher temperatures. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin-hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating. 206 B size hardener is matched for use with 105 B size resin.

Review: I use this with the 105 resin to fill cracks and imperfections in solid wood. You can either dye it to a color you want or use it clear as is. You’re going to end up with a lot of bubbles as with any epoxy, but I use a small torch with indirect heat to pop those and get a perfect finish every time. It’s difficult to work with so if it’s your first time I would recommend watching some videos on YouTube or something to learn more before you dive in. But the product works exactly as intended. Don’t expect to fill a large crack all in one pour. Work in stages or you’ll end up with voids. Get the pumps that they sell as well in order to get the perfect mix and make it easier on yourself.
