- Instructions for Use
- If PART A is solidified or crystallization hasoccurred, heat to 40-50°C until liquid. If full pot life isdesired, let cool to room temperature before use.
- Mix 100 grams of Resin, PART-A with 35 grams ofHardener, PART-B and vacuum degas.
- Apply to clean bonding surfaces and cure asrecommended to achieve the desired properties.
- Typical cured properties were determined usingrecommended cure schedule.
- Some difference in properties may occur with thealternate or other cure schedules.
