Cerakote C is about half as tough as Cerakote H -
Salt Spray (ASTM B117)
350 hrs vs 1000 hrs
Scratch Hardness (ASTM D3363)
h vs 2H
Adhesion (ASTM D3359 - 09)
4b vs 5B
Impact (ASTM D2794)
80 /20 inch-lbs vs 160 / 160 inch-lbs
most of these firearm finishes don't use internationally recognized ASTM Standards but puffy adjectives to describe their product making comparisons difficult. GunKote uses some ASTM but not others. But since NIC does it makes comparisons pretty easy within their product line.
ETA - Here is Larsons Tactical's view who uses all the main brands (Duracoat, Gunkote, Cerakote)
DuraCoat is a hard polymer thats self lubricating to a certin extent; extremely hard, oil, solvent, and wear resistant. It resists 100 inch pounds of direct impact and 80 inch pounds of reverse impact. Its pencil hardness runs H to 2H. DuraCoat has passed a 300 hr salt spray test, which far exceeds military requirements for firearms finishes. Major manufacturers such as DSA utilize DuraCoat finishes on their rifles. DuraCoat has proven to hold up extremely well under field conditions. Even on parts such as FAL bolts, which are subject to significant abrasion as the bolt cycles, DuraCoat has held up well and proven to be extremely durable. DuraCoat will dry to the touch in 20 min and can be used after curing 6 - 8 hrs. How ever it will continue to cure for 4 to 6 weeks after application. DuraCoat is not a flash cure application which will become brittle after curing resulting in chipping and flaking. DuraCoat cures slowly so it remains flexible after it cures which contributes to its excellent abrasion and wear resistance. We like to say DuraCoat doesn't wear out, it wears in. DuraCoat can be applied over just about any surface including, metal, plastic, or wood as long as the surface is properly prepared. We have had great success using it on forearm rail covers such as the textured Magpul covers. DuraCoat is available in 55 stock colors and 7 new electric colors. With 3 Mirageflage camo patterns , 2 advanced camo patterns and 11 standard camo patterns available, a color / pattern is available for any terrain.
DuraHeat is available for parts that will be exposed to extreme heat. This high performance coating is capable of with-standing temps of up to 1800 degrees. DuraHeat is an excellent choice for barrels that will see sustained fire such as LMG barrels or full auto rifle barrels When exposed to these types of high temps DuraHeat becomes even harder and more abrasion resistant. It is available in matte black, HK black, woodland brown, woodland green, woodland tan, stainless, & pewter.
DuraBake Enamel is an extremely durable enamel which provides the ultimate in protection. It can be applied to all ferrous metals, alloys, & plastic. It is available in woodland tan, woodland green, woodland brown, matte black, parker, desert mint, desert beige, desert brown, OD green, snow gray, & white.
KG Gun Kote was developed for use on military weapons. The United States Navy Seal Teams were the first units to use this product. There was a need for a material that would hold up under extreme adverse conditions. The coating needed to withstand 500-hour salt spray tests and still meet the military machine gun firing requirements... Gun Kote does this and its application has grown from Firearms to Automotive/Motorcycle and Industrial applications, being used on heads, cases, barrels, oil coolers, radiators and engine blocks.
Gun Kote is a thin hard coating that will give excellent protection from abrasion. It is not easily worn off such as bluing, phosphate or chemically blackened surface treatments, which can leave metal surfaces, bare and unprotected from the elements. Gun Kote does not attract dirt or dust, has excellent impact resistance and can be formulated to be non-reflective. Gun Kote comes in two formulations; 2400 Series which use molybdenum or PTFE as a lubricating base and the 1600 Series which have a high concentration of PTFE.
When Gun Kote is properly applied it will provide:
* Outstanding corrosion protection. Gun Kote will withstand a minimum of 500-hour salt spray tests at 5% salt, however, tests performed for Armscor by the South African Navel Logistics Dept. showed Gun Kote withstanding an equivalent of a 7-year exposure. (Tests were performed on Aluminum in a salt spray chamber with 50/50 on/off time at 35 degrees C.)
* Resistant to chemicals, oils and solvents common to Automotive and Aircraft Industries.
* Helps to cool parts by dissipating heat. Gun Kote will withstand temperatures over 500 degrees F and as low as -320 degrees F.
Gun Kote can be applied to all ferrous and non-ferrous metals, over all types of plating and even some plastics. Available in several colors including: Black, Gray, OD Green, Stainless Steel, Service Brown, Tan and the New Clear Kote. Gun (Colors available are in Flat) .
CeraKote is our top of the line coating. If you want the very best coating available look no further. CeraKote was developed by NIC Industries, Inc. CeraKote was designed to provide a high quality, long lasting finish, with high corrosion protection and durability. CeraKote is available in two compounds "C" series which is an ambient cure coating & "H" series which is a thermal cure coating. Unlike Teflon based gun coatings the "C" & "H" series of CeraKote offer unparalled levels of hardness and abrasion resistance because of their unique ceramic backbone.
CeraKote is available in 31 standard colors. It provides excellent corrosion protection, outstanding abrasion resistance, extreme hardness, & unmatched durability. CeraKote surpasses Teflon based coatings for wear resistance by well over 60%. CeraKote has self lubricating elements incorporated through out the coatings matrix, this allow firearms to function with little or no fluid lubricants that typically attract abrasive dust particles. CeraKote performs extremely well in automatics with high cyclic rates.
The "C" series ceramic gun coatings were designed as a single component ambient cure system. As higher tempatures are reached the "C" series will flux, becoming harder and more abrasion resistant. After a full cure this coating provides excellent resistance to most cleaning solivents and chemicals. It has a pencil scratch hardness (ASTM D3363) of 7h, exceeded the 5% salt spray test (ASTM B117) with well over 550 hrs, an adheasion cross cut tape (ASTM D3359) of 5B, & has an optimal film thickness of 0.5 to 1.0 mils. It has a heat stability rating in excess of 1200 degrees f for extended periods without failing.
The "H" series was designed as a two part thermal cure system. It provides a very high quality, long lasting finish with high corrosion resistance. It offers unparalled levels of abrasion resistance and hardness because of the two part component system. The "H" series has a viscosity #2 Zahn cup of 13.0 sec, an optimal film thickness of 0.5 to 1.0 mils, passes the 5% salt spray test (ASTM B117) in excess of 2,500 hrs, has a pencil scratch hardness (ASTM D3363) of 7h, the adheasion cross cut tape (ASTM D3359 of 5B, and heat stability of 525 degrees f for extended periods without failing.
