Here is Review of JVZOO Product with topseller status.

Dacromet is a trademark of Metal Coatings International, and it describes Dacromet coating. It is a way of applying a sacrificial coating of zinc. My understanding is that it offers greater corrosion resistance than zinc electroplating (probably because it’s thicker).

Salt spray testing is not really a meaningful way to predict the life span of zinc-based coatings though. The protection they afford in real life comes from the development of stable and insoluble zinc carbonate corrosion products that develop over time with exposure to the fractional co2 in the open air.

“The Ideal Finish” is something the business has sought for a long time. It is really an elusive concept which huge amounts of money have been spent developing, testing and qualifying possible alternative finishes, but many of these efforts happen to be futile. Each finish, from phosphate to cadmium, has strengths and weaknesses that must definitely be weighed for each application. Using these considerations, progress can be created toward utilizing the materials who have the nearest resemblance for the strengths of cadmium which can be required and, consequently, accepting their weaknesses.

This paper describes a research study conducted on eight finishes which can be potential replacements for cadmium. Details are specific to fasteners in terms of clamp load and corrosion, both cosmetic and galvanic. The scope was broadened to know many components of each finish to offer engineers information vital to recommending their use as cadmium substitutes and exposing weaknesses of each and every finish. One inorganic alternative was found as a drop-in alternative to cadmium, and another two were found to closely resemble cadmium’s performance in most respects except for electrical conductivity.

Because cadmium offers excellent corrosion resistance, consistent torque-tension, bimetallic compatibility and thickness within standard thread tolerances, it has been most engineers’ finish of choice for a long time. It is still found in many applications that cannot sacrifice the qualities that Best Zinc Flake Coating Line Manufacturer offers.

Initially, automotive OEMs established a deadline to get rid of cadmium by 1995. Chrysler enacted testing programs to fill the hole in its fastener finish requirements.1 Chrysler conducted a Form of Experiment (DOE) to qualify alternatives that met strict performance requirements and in addition followed OSHA and EPA regulations. This DOE resulted in your selection of the Dacromet 320® L coating system as it closely resembled cadmium in fastener applications. As a result, Chrysler was compliant with OSHA and EPA regulations before the established deadline. Metal Coatings International Inc. (MCII) was associated with this DOE.

Because of the extreme use of its equipment in critical situations, the military continued to use cadmium for many applications. The delay in switching from cadmium-plated hardware proved beneficial because automotive OEMs compiled much information in that time. The military sorted through the data made by automotive qualifications and selected zkqjlg coatings that performed well in the predetermined areas, which in-turn resulted in a substantial cost benefits.

3 years ago, the Army embarked on a cadmium replacement journey, testing numerous finishes as potential candidates.2 Although no “perfect finish” was discovered, this testing ended in the qualification of the solvent-based coating that closely resembled Full Automatic Dip Spin Coating Machine DST S800+ in terms of corrosion protection, bi-metallic compatibility and clamp load retention. The weaknesses exposed were insufficient conductivity, high coating thickness as well as the reliance upon a supplemental lubricant to meet Army torque charts. Another attribute that really must be considered is the fact this coating was solvent-based and thus loaded with volatile organic compounds (VOC). As a result of VOC content, application facilities required expensive air treatment equipment to reduce pollution that otherwise would have escaped to the environment.
