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.
