Use of Accelerator B Component

The reaction profile is adjusted prior to pumping by the addition of  Accelerator B into the base resin and is affected by temperature and the amount of moisture encountered. At 2.5% (1 pint per five gallons), the expansion will start at 15 seconds and be complete at about 65 seconds. These reaction times were determined at 77°F with the addition of 2.5% water.
