Can Calcium Sulfonate Products be Applied Over Damp, Rusted Surfaces?
Calcium sulfonate resins adhere and perform well over poorly cleaned metal surfaces including, rusty metal and damp surfaces. The calcium sulfonate has a higher affinity for metal than water does. This gives products that contain calcium sulfonate resins the ability to displace water from metal surfaces. The carbonate platelet increases the path length that oxygen or water would need to take to reach the metal substrate. The resins that form the matrix between the platelets provide further resistance to moisture penetration, increasing corrosion protection. Back to Top 6) What Kind of Temperature Resistance Does Calcium Sulfonate Products Have? Modified Calcium Sulfonate does not exhibit a melting point. Any softening or dropping points are in excess of 500 F. Modified calcium sulfonate remains flexible even when frozen in an applied coating. In concentrated solutions, modified calcium sulfonate has little tendency to separate or settle due to their thixotropy at temperatures from 0 to
