Frequently Asked Questions
What is Pre-filled?
Pre-filled means the resin or hardener has been filled with silica sands before delivery for convenient processing.
Is Pre-filled resin cheaper than Pure resin?
Generally yes, but consider final costs including local silica sand availability and shipping expenses.
Why doesn't JiangTe resin offer Flexibilizer and Accelerator separately?
These components are already added into the resin/hardener before delivery for simplified processing.
