206 SLOW HARDENER

206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working time or a longer cure time is needed. It also provides adequate working time at higher shop temperatures. When combined with 105 Resin in a five-part epoxy resin to one-part hardener ratio, the cured resin/206 Slow Hardener mixture yields a rigid, high-strength, moisture-resistant solid bond with excellent bonding and barrier coating properties. 206 Slow Hardener is not intended for clear coating.

206 SLOW HARDENER Facts

BONDING & CLAMPING

There are two types of structural bonding with epoxy. Two-step bonding is the preferred method for most situations because it promotes maximum epoxy penetration into the bonding surface and prevents epoxy-starved joints. Single-step bonding can be used when joints have minimal loads and excess absorption into porous surfaces is not a problem.

GLUE STARVED JOINT

If an epoxy filler is not used and a high clamping force is used, the result can be a glue-starved joint which will make bond failure much more likely. Glue-starved joints are weaker than their counterparts. Avoid glue-starved joints by following the one- or two-step bonding method.
