CarboStop 402 resin consists of modified isocyanates with additives. CarboStop 402 ACC is a catalyst mixture designed to adapt the reaction speed to the situation.
To adapt the reaction speed, the accelerator CarboStop 402 ACC is added to the resin and mixed before pumping.
The reaction begins when the mix comes in contact with water. The reacted material has a high amount of closed cells under compressed as well as free rise conditions.
