Welcome to our new and improved newsletter format.  There are many new features to the newsletter which you can explore.  Our goal is to provide links, charts, pictures and any other materials here that you can use to sell the benefits of coatings to your customers.  We are always open to suggestions for improvements and additions, so please feel free to contact us and let us know what you think. 
 
This new service will provide instant feedback as to what is working and what is not.  Also, some of you may see that we have "recycled" some of our material.  As we are expanding our newsletter base we wanted to make sure the most important messages were once again introduced.  New content and "older" content will be mixed over the coming months.
Bi Metal Corrosion
 
Aluminum Tube Showing Bi Metal CorrosionAll metals are susceptible to corrosion.  The most common and well known cause of corrosion is from exposure to moisture in the air.  A lesser known cause is the joining together of two dissimilar metals.
 
Bi metallic corrosion occurs when dissimilar metals are in contact in the presence of an electrolyte (e.g. water).  The corrosion of the metal, the anode, results from a positive current flowing from the anode to the less reactive metal, the cathode, through the electrolyte.
  
An example of this is shown in the picture.  The picture shows holes where three bolts were installed into an aluminum tube and then removed after 880 hours in salt spray testing.  Hole bottom left had a zinc plated bolt installed, hole in the middle had a stainless steel bolt installed, and hole top right had an RIE coated bolt installed in it. Not able to be seen in the picture is the serviceable effect that corrosion had on the bolts.  We were able to easily remove the nut and bolt coated  by RIE.  However, the zinc plated bolt required a lot of manipulating and the stainless bolt snapped off in at least 50% of the tests.
 
As an example, we frequently combat bi metallic corrosion for aluminum dock and lift companies as well as aluminum trailer companies.  In these cases we eliminate expensive and susceptible stainless steel with less expensive and stronger RIE coated fasteners.
You can use this selling point to earn your customer's loyalty and respect as a leader in innovative product enhancement and at the same time offer increased customer savings.
 
Spotlight Customer of the Month
 
Coated Bolts 001Each month we will spotlight one of our customers and their success story.  We will be changing the names of the persons and companies involved to protect confidentiality agreements and relationships.  We want you to submit your story to us.  If we choose to use it, we will send you a special gift from RIE.  If we are inundated with submissions we will include two per month.
 
     We received a call from Gina after RIE Newsletter 10.  Gina had been reading all of the previous RIE newsletters.  In the back of her mind knew she had a customer who might be a good fit for the coatings we provided. 
     One phone call to us seemed to make it all click for Gina.  She explained her logisitcal issues from a supplier standpoint and then talked about the issues her customer was having on the manufacturing side of things.
     A coating was specified, samples were issued, tests were done and in a matter of a few weeks, full production was underway utilizing RIE Coatings. 
     Gina was praised by her customer for bringing innovative ideas to a very innovative manufacturing company. 
 
     In her words:
 
     "About a year ago, a customer approached me wanting a coating that would outlast the life of their product. After lots of research I found RIE Coatings and Magni 567 Silver. Brian was very helpful with conference calls and with quoting very competitive pricing. When we started sending in product to be coated, Bev and Scott in production were awesome to deal with. They were very personable and attentive to our tight schedule and needs. The whole team has been a blast to work with and I look forward to many years to come! Thanks again - you guys Rock!!!"
Why Coat?
 
Wind Tower Field in OceanThere is a perception that coatings cannot be as good as galvanizing or plating when in fact the opposite is true.  Coatings have been used in the auto industry for many, many years and have only in recent history been utilized in other (non-automotive) manufacturing enviroments on a larger scale.  The uses for coatings are endless and the benefits have greatly enhanced how fasteners and other parts are used and protected. 
 
Coatings provide superior corrosion protection through self healing organic and inorganic ingredients.  They provide protection against bimetal corrosion by blocking electron flow.  They provide protection against chemicals, treated lumber, high and low temperature and abrasion.  Benefits included in the coatings are dry film lubrication and a thin film that allows for consistent gauging and torque and tension control.  Our coatings meet RoHS and EVL standards.
Thank you for taking the time to explore the new RIE Newsletter format.  We hope that the information provided is useful to your everyday business as well as informative on coatings.  Please feel free to send in your stories for the spotlight of the month as well as any content suggestions.
 
Sincerely,
