| To control the exotherm, the process as described suggests slow addition of propionyl chloride. |
|
| In addition, the lower heat of cure of the BZ system offers a lower exotherm potential. |
|
| As anticipated both monomers show a typical minimum temperature and curves of exotherm attributed to ring opening polymerization. |
|
| They meet ASTM F1216 requirements and reduce the likelihood of stress cracking and shrinkage with a lower exotherm in the enhanced version. |
|
| The resultant mixture polymerizes completely over a short period with a high exotherm. |
|
| The resin has high SPI peak exotherm and low cure time that allows faster production rates. |
