Penetrant/Lubricant has wear-resistant dispersion formula.
May 4, 2004 - Liquid Wrench® includes Cerflon® ceramic-reinforced, chemical-resistant fluoropolymer to provide lubricity and wear resistance. Incorporated dispersion combines polytetrafluoroethylene (PTFE) with boron nitride. Normalized results from Ball on Cylinder Lubricity Evaluator show that base oil provided lubricity of 100; 111 with boron nitride; 119 with PTFE; and 127 with PTFE and boron nitride. Solids level for tests was 1%.

Boron Nitride/PTFE Dispersion Boosts Performance of Liquid Wrench L4
(Amherst, NY; February 13, 2004) -- A new additive technology is playing a major role in the ability of Radiator Specialty Company’s Liquid Wrench® additive to provide lubricity and wear resistance superior to other penetrant-lubricants. The new additive, called Cerflon® and produced by Acheson Colloids, Port Huron, Michigan, under a license with Ceramic Reinforced Technologies, is a dispersion that combines polytetrafluoroethylene (PTFE) with boron nitride. The boron nitride used in the application was specially engineered by Saint-Gobain Ceramics, Boron Nitride Products, the exclusive supplier of boron nitride powders for Cerflon® products, to meet critical dispersibility and particle size requirements. “We recognized the value of engineering specific Boron Nitride powders to address the critical-to-quality characteristics required for Acheson’s Cerflon® development program,” said William Hill, Director of Operations for Saint-Gobain Ceramics. “Our test results showed that the dispersion of PTFE and boron nitride performs far better than PTFE alone,” said Larry Beaver, Vice President of Technology for Radiator Specialty. “As a result, we believe that Liquid Wrench L4 offers the best combination of lubrication, penetration and protection of any product on the market.”
Cerflon® is a ceramic reinforced fluoropolymer, a class of plastics known for their excellent chemical resistance. “Our experience is that Cerflon® provides a substantial improvement in both durability and lubricity compared to PTFE in every lubricant application where we have tried it,” said Andrew Hamilton of Acheson Colloids. Test results that show the synergistic effect of combining boron nitride with PTFE played a major role in Radiator Specialty’s decision to utilize Cerflon® in Liquid Wrench L4. Normalized results from the Ball on Cylinder Lubricity Evaluator (BOCLE) (ASTM D5001) show that the base oil provided a lubricity of 100; the base oil with boron nitride provided a lubricity of 111; the base oil with PTFE provided a lubricity of 119; and the base oil with PTFE and boron nitride provided a lubricity of 127. The solids level for the tests was 1%. Howard Leendertsen of Ceramic Reinforced Technologies (CRT), the patent holder for Cerflon® technologies pointed out that other applications under study and testing are automotive lubricants including motor oil, greases, industrial lubricants and greases, food processing lubricants and greases, as a process aid and as an additive for coatings to enhance wear or corrosion resistance to name a few.
“Saint-Gobain was picked as exclusive boron nitride supplier to Cerflon® because we knew through experience that they could meet our stringent material requirements while also offering customization capabilities that would allow us to steadily improve the product,” Hamilton said. “The value of boron nitride in this application is its ability to reinforce PTFE, increasing its lubricity and wear resistance,” said Gene Pruss, Senior R&D Engineer for Saint-Gobain Ceramics. “We understand how different types of boron nitride interfaces with other polymeric materials. The boron nitride used in this application has been specially engineered to meet critical dispersibility and particle size requirements. The engineered powder disperses very evenly into the PTFE carrier. Hill said, “The Cerflon® product line has resulted in the development of a family of IDL BN powders to meet the needs of this emerging technology.”
