Precision Coatings
PC-702® is a new engineered thermoplastic that has high thermal stability and outstanding chemical resistance. It’s exclusivity to Cape Coatings opens fresh worlds of fusion bonding strength. Its application and profile allow us to coat low tolerance areas that have been out of bounds to normal epoxy type coatings.

Typical advantages to PC-702®
PC-702® is a dry powdered coating process that will enhance the durability and longevity of normal steel parts. In practical tests, outlasting stainless steel parts is not uncommon.
A thermally bonded polymer that protects threads without compromising the makeup or tolerance of the parts connections. This is not possible with fusion bonded epoxies, due to their thickness. Produces smooth, even 1-4 mils of protective coating to all areas of metal parts. There are no exposed areas. PC-702® provides resistance to hydrogen sulfide (H2S), carbon dioxide (co2), oxygen, salt water and stimulation acids.
High temperature reaction (700° – 750°F) results in thermal stability and eliminates pin-holes in the coating. Reduces Total Cost of ownership. More durable than plastics, ceramics and epoxies. Exotic metals such as aluminum bronze, stainless steel, and titanium can be replaced with ductile iron or carbon steel when protected by PC-702®.
Teflon FEP coatings have proven success in applications where preventing asphaltenes from sticking to moving parts is essential. Teflon has excellent corrosive resistance, so combining its slick release with its anti-corrosive element, makes this a formidable coating for oil and gas parts.

Teflon Characteristics
The following characteristics are common to all Teflon™ coatings in varying degrees. The unique combination of properties inherent to all Teflon™ industrial coatings make them a natural choice in a number of industries.
|
NON-STICK - Very few solid substances will permanently adhere to a Teflon™ coating. While tacky materials may show some adhesion, almost all substances release easily. Wear due to sliding is very low due to the anti-adhesive properties. For many applications, a significant problem is the buildup of foreign particles, and Teflon™ nonstick coatings’ excellent release qualities help solve these issues. |
|
LOW COEFFICIENT OF FRICTION – Friction is a force created when two objects rub together that hinders the motion. With a Teflon™ industrial coating, the coefficient of friction is generally lowered to a range of 0.05 to 0.20, depending on the load, sliding speed, and type of coating used. Lubricity is very important in any application that has moving parts touching each other. |
|
CRYOGENIC STABILITY - Many Teflon™ coatings can withstand temperatures as low as -454ºF without loss of physical properties. Their ability to withstand sub-freezing temperatures means that Teflon™ industrial coatings will not lose any of their other characteristics when exposed to such low temperatures. |
|
CHEMICAL RESISTANCE - Chemical environments usually do not affect a Teflon™ fluoropolymer coating. The only chemicals known to affect these coatings are molten alkali metals and highly reactive fluorinating agents. Permeation resistance due to the low porosity of the coatings means that they are extremely corrosion resistant and are chemically inert. |

ABRASION RESISTANCE - Teflon™ coatings are very resistant to scratches and abrasion due to their excellent durability and toughness. Surface scarring is minimal, especially in certain coatings when fillers are added. |
