Curative for protective marine and infrastructure coating

curative help to combat this challenge. This new technology is yet another example of our company’s commitment to proactively addressing its customers’ needs.” In addition to demanding marine topcoat applications where resistance to seawater, ultraviolet light and chemicals is critical, SiVance’s C1008 curative technology is designed for coatings for piping, bridges, wind turbines, offshore platforms, tank exteriors, structural steel and heavy equipment. It utilises a proprietary molecular structure that provides enhanced compatibility in epoxy systems. The product is fully miscible with hydrogenated bisphenol-A epoxy resins. Compatibilisation of C1008 curative in other epoxy resins is possible with the use of solvents (methyl ethyl ketone (MEK), xylenes, etc) or reactive diluents.

SiVance ® C1008 curative, from Milliken subsidiary SiVance LLC, is a new silicone curative that improves the durable flexibility of epoxy polysiloxane protective topcoats in marine and infrastructure applications, without sacrificing weatherability. The development of the new curative technology solves a major challenge common to epoxy polysiloxanes: brittleness and cracking that can develop over time as the coating cures. “Our new C1008 curative is a much- needed solution for increasing the performance and toughness of protective epoxy polysiloxane topcoats used in highly corrosive environments,” said Jeff Jones, business development director, SiVance LLC. “Regular maintenance on marine applications and infrastructure can be very time consuming and costly, but protective coatings made with SiVance’s C1008
