205 FAST HARDENER

205 Fast Hardener is formulated for general coating and bonding applications at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. 105/205 forms a high-strength, moisture-resistant solid bond with excellent bonding and barrier coating properties. Not intended for clear coating.

205 FAST 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.

COLD WEATHER BONDING

It’s that time of year when we are keen to complete projects before the winter freeze sets in. As cold can compromise the strength of a cure, what can we do to speed up the process?
