Instructions for Use and Precautions
- MEKP may be used as the curing agent at a concentration of 1.0–2.5%. Ensure the curing agent is within its shelf life.
- Palatal P 50-952TV resin already contains an accelerator. After prolonged storage, the thixotropic agent in the resin may gradually settle; ensure it is evenly dispersed before use by inverting and rolling the drum several times or stirring the contents gently.
- To optimize the performance of the finished product, post-cure for several hours at 80°C.
