Accelerator component for SealBoss hydrophobic polyurethane injection products. Compatible with SealBoss 1510, 1570, and 1570LV. Mix to be 2-20% depending on desired reaction and job site conditions. In situations of high water flow rates and /or low temperatures, ratios may be increased to 20%. For hairline crack injection and soil stabilization ratios may be lowered to less than 5%. Observe temperature and humidity of the environment, since both determine the pot-life of the premixed batch. Do not mix more material than the amount that will be pumped within reasonable time. Rule of thumb: High temperatures and high humidity decreased gel-time.
