Question
What is a thixotropic resin?
Expert Answer
A thixotropic resin is a material that is thick (viscous) at rest but becomes fluid when agitated or pumped. This property is crucial for overhead injection work (e.g., ceiling cracks) or wide cracks. If a resin were too runny (low viscosity), it would drip out of an overhead crack before curing. Thixotropic epoxy pastes stay put, ensuring the crack remains filled while the bond cures.
