Explosion-proof Fast-drying Castables

Brand: PN-SP

To shorten baking time of industrial furnaces, explosion-proof fast drying castables are developed by PRCO. Comparing with conventional castables, the baking time may be reduced from around 10 days to 3-5 days, so downtime and cost is dramatically saved.

The PN-SP fast drying castables are titled high-tech products which have been listed in National Level Torch Project and several other prizes such as Provincial Level Science & Technology Advancement. They are ideal solution for installation and maintenance of various industrial furnaces.
