SiVance Launches Silicone Resin to Help Extend Durability of Protective Coatings

Published on 2016-08-22. Author : SpecialChem

SPARTANBURG, S.C. – SiVance, LLC, a subsidiary of Milliken & Company has introduced SiVance® C2010 resin, a new reactive silicone technology designed to create highly durable epoxy-silicone hybrid coating formulations. Specifically, this unique, high-performance material helps extend the flexibility and impact resistance of protective coatings used in harsh operating environments such as:

  • Undersea drilling
  • Hydraulic fracturing 
  • Chemical manufacturing

Extending the Durability of Epoxies

Compared to coatings made with competitive products, hybrid formulations featuring SiVance C2010 resin enable formulators to help their customers avoid the cracking, delamination and blistering that lead to corrosion and failure of metal pipes, tanks and equipment.

“While epoxies for protective coatings have been enhanced over the years, they are approaching their limits,” said Jeff Jones, SiVance business development director. “At the same time requirements for today’s extremely demanding environments are escalating. SiVance C2010 resin gives formulators a powerful new tool for extending the durability of epoxies under the harshest of conditions, helping end customers reduce maintenance, replacement costs and downtime.”

Standing Up to Tough Conditions

Due to their brittle structure caused by a high crosslink density, epoxies are susceptible to cracking and delamination when exposed to heat, chemicals and hot water. Replacing a portion of an epoxy coating system with SiVance C2010 silicone resin creates a hybrid that can better absorb stress from reverse impact and thermal shock. SiVance C2010 is:
  • More flexible
  • Thermally stable 
  • Hydrophobic than epoxy 

To facilitate formulation of these hybrids, SiVance C2010 resin uses a proprietary structure that makes it broadly compatible with aliphatic epoxies and aromatic epoxies such as bisphenol-A, bisphenol-F and phenol novolacs.

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. Industry processes that can benefit include oil and gas exploration and extraction, offshore and marine operations and chemical manufacturing.

Adding Value to Epoxy Coatings

Ever-deeper undersea drilling operations, for example, subject coatings to higher temperatures and pressures. Laboratory tests under these conditions showed that a bisphenol-A epoxysilicone hybrid formulation made with SiVance C2010 resin far surpassed a bisphenol-A epoxy formulation in flexibility (conical mandrel bend test and a three-point bend test) and reverse impact performance (ASTM D2794). These improvements in flexibility and impact resistance were achieved with only a minor decrease in other critical properties, including hardness and glass transition temperature, and had little to no impact on adhesion.

Although organic modifiers and other reactive silicones provide similar flexibility upon curing, they lose this property more rapidly than SiVance C2010 resin under exposure to demanding environmental extremes.

The new C2010 resin is available globally in commercial quantities and is currently registered under the Toxic Substances Control Act (TSCA) with other global approvals in progress.
