Reported values are not independent test results. Original units and table wording are preserved. Extracted TDS rows can depend on the grade, component and source table headings; use the linked page to verify that context. Test methods, sample preparation and cure schedules may differ; consult the original TDS before making a performance comparison.
Selection & processing checks
Compare the complete resin–hardener system. A different hardener or cure schedule can change the cured properties.
- Is the stated ratio by weight or by volume?
- Do the thermal and mechanical values use the same cure schedule?
- Is the formulation designed for casting, bonding or encapsulation?
- Confirm the complete product designation, including any hardener, color or formulation suffix.
- Read the current SDS for handling, protective equipment, storage and disposal information.
The reported weight ratio for this record is 100A:16B. A weight ratio must not be used as a volume ratio without the appropriate density information.
Missing properties are not estimated. Similar values or shared application labels do not establish a drop-in replacement.
