SiVance L.L.C., a subsidiary of Milliken & Co., has introduced SiVance C2010 resin, a reactive silicone technology designed to create highly durable epoxy-silicone hybrid coating formulations.
SiVance said the high-performance material helps extend the flexibility and impact resistance of protective coatings used in harsh operating environments such as undersea drilling, hydraulic fracturing and chemical manufacturing. Compared to coatings made with competitive products, hybrid formulations featuring SiVance C2010 resin help their customers avoid the cracking, delamination and blistering that lead to corrosion and failure of metal pipes, tanks and equipment, the company claimed.
Coatings formulated with an epoxy-silicone hybrid offer increased durability in highly demanding applications, such as immersion coatings, tank linings, thermal insulation and subsea coatings, the company said. Undersea drilling operations, for example, subject coatings to higher temperatures and pressures, SiVance said, and lab tests under these conditions showed that a bisphenol-A epoxy-silicone hybrid formulation made with SiVance C2010 resin surpassed a bisphenol-A epoxy formulation in flexibility (conical mandrel bend test and a three-point bend test) and reverse impact performance (ASTM D2794), with only a minor decrease in other critical properties, including hardness and glass transition temperature, with little to no impact on adhesion.
