Slurries and Fluoropolymers

Blue Armor is a proprietary seamless fluoropolymer coating system based on ECTFE and modified for improved processability and abrasion resistance. It is designed to protect processing equipment from chemical attack, abrasion and thermal shock in temperatures up to 300°F (149°C), with full vacuum rating over the entire pH range. The stable molecular structure and low porosity of Blue Armor makes it an outstanding corrosion barrier ideal for coating complex components and processing vessels.

Our SermaGard^® composite coatings are composed of various binders combined with metallic, ceramic or thermoplastic materials. Our predominant binder system is a unique, water-based, inorganic material that cures at a low temperature to produce a ceramic bonding matrix.

Depending on the additive materials and topcoat selected, SermaGard coatings can deliver a variety of resistance combinations, including a unique capability to combat aqueous corrosion and heat. They also offer chemical, oxidation, thermal shock, wear and abrasion resistance and create superior lubricity, release and sealing characteristics.

In the SermaLoy^® process, a slurry is applied to the component surface, then diffused. The result is an aluminide-diffusion coating that adheres tightly to the part surface and is very resistant to both low- and high-temperature hot corrosion and oxidation.

Typical applications include gas turbine hot section parts and industrial components.

SermaShield 1000 is a family of coatings based on Fluoroshield PFA technology and PST's proprietary bonding technology. This family is comprised of six technically-advanced seamless coating systems that combines both chemical and mechanical bonding technologies to provide superior corrosion protection in temperatures as high as 500°F (260°C), with full vacuum rating over the entire pH range. Each coating system is applied as an aqueous dispersion at room temperature, making it ideal for coating complex components or large vessels up to 30,000 gallons in size.
