Pretreatment Is Key to Long-Lasting Corrosion Resistance

Resisting shortcuts also lengthens the life of decorative impact.

By Crest714c|March 7th, 2019

There are many powder coatings that provide long-lasting, protective, corrosion-resistant surfaces. Powder coatings can be both decorative and corrosion-resistant for specific environments, but most important for the durability of the coating over the long term is the thoroughness of the pretreatment phase.

The most popular corrosion-resistant decorative powder coatings fall into a few categories based on their base formulas: epoxies, polyesters, epoxy-polyester hybrids, and fluoropolymers. Each of these can maximize corrosion resistance—and long-term durability—if you understand their strengths and apply them with the end-use in mind.

The thing is, powder coatings always look great when they’re new. But when that new finish doesn’t last as long as expected, or when it doesn’t provide corrosion resistance as expected, how do you know what the cause is? You don’t always know, because the answer is hidden. More often than not, the coating begins to fail because someone took a shortcut during the pretreatment phase.

Thorough Pretreatments

Substrate preparation and pretreatment for powder coating is as important as—or more important than—the coating itself when it comes to corrosion resistance. Pretreatment is essential to ensure both product longevity and outstanding appearance.

When we talk about pretreatment, we usually mean sandblasting, a chemical conversion treatment, or both. Sandblasting can be done with aluminum oxide, steel shot, or garnet. There are lots of chemical conversion treatments out there, but we use zirconium, iron phosphate, and zinc phosphate. For long-lasting corrosion resistance, we recommend our in-house, six-stage zinc phosphate process for all ferrous substrates and our six-stage zirconium process for all non-ferrous substrates. 

There are many ways to cut corners on pretreatments. These include shortening the pretreatment time, not staying within the recommended temperature range, failing to maintain chemical titration, failing to adjust pH, and not maintaining your water purity.

At Crest Coating, our emphasis is always on producing the highest quality finishes possible. We use the latest in electronic measuring and monitoring equipment, in-house RO and DI water systems, and quality control that complies with ISO9001:AS9100 standards.

I wrote about this last year but felt it was worth repeating…

Now that you’ve taken care of the lingering sticky note reminding you to get that quote done, you’ve received enough of them back to begin the task of comparing the details. Which has the best price? Are they offering the same services for the pricing offered, etc.? Is their quality up to your standards? You know the drill. One thing to keep in mind is the famous quote: _“The bitterness of poor quality remains long after the sweetness of low price is forgotten.”_ (Some say it was written by Benjamin Franklin but that is up for review on the Internet. Still a great line.)

I read this quote years ago in, of all places, a yellow page phone book…do you remember those? Pretty archaic these days but this quote stayed in my mind forever. And it’s true of anything, the new vacuum cleaner, auto detailer’s work, your kid’s math tutor…but especially for your parts. They have to fit in with all the other components and one error can throw the whole project into utter chaos. So, make sure you are getting the best value for your dollars. Scrutinize those quotes thoroughly and take everything into consideration, not just the lowest price. (I know you knew that already…I just wanted a chance to use my favorite quote:)

Enjoy this beautiful day!

Assistant Lillikoi

September, 2018

Hello…I’m going off-message today. Time for a little break from the routine.

This is my new assistant, Lillikoi. I thought I should introduce her to you since she occasionally likes to add her paws-worth to my emails. I’m not sure she’s gonna work out though. Her work ethics aren’t that great and her breaks are always too long. I must say though, she is good company and never gossips at the water cooler.

Enjoy this beautiful day!

“Solitare – the only game in town”… I have the song Solitare by Neil Sadaka (and Clay Aiken) stuck in my head this morning…so my spin off will be, of course, _your current supplier is not the only game in town…._

Try not to get too complacent with your suppliers. Keep getting those estimates done every now and then from other vendors. If nothing else, it will show you where things stand and if all is okay great. But if service has taken a dive and prices have increased, well it’s probably a good time to have someone else give you current pricing and a chance to show you that you just might be able to get better service.

I know things are iffy now with the new tariffs being thrown around like soccer balls, but someone told me just last week, that sending their product off-shore might end up more expensive than manufacturing it locally. Having to pay tariffs to bring it back in the USA will need to be taken into consideration. So, although things are still up in the air, now is a good time to look into local suppliers. Staying ahead and up to date is always to your advantage.

Enjoy this beautiful day!

Cal-Tron Corporation Wins Northrop Grumman Award

Cal-Tron Corporation (Pioneering Plastic Solutions since 1942)

Karen Leatham (center) accepts 2015 WCT Award

Karen Leatham, Operations Manager, CTC (center)

Cal-Tron Corporation recently received one of Northrop Grumman Corporation’s World Class Team awards for their outstanding performance in support of its Global Supplier Diversity Programs (GSDP).  Cal-Tron was one of only 34 suppliers who received this honor out of a supplier base of more than 9,500 companies worldwide.

This award is given to companies demonstrating exceptional support and commitment to the GSDP goals and objectives using criteria such as product, service and quality. Other considerations included demonstrated delivery performance, outstanding program support, superior technical achievement and reported cost performance/competitiveness and/or continuous process improvement.

Karen Leatham, Operations Manager, and Christina West, Administrative Assistant, daughter and granddaughter of Dan Pool, the owner of Cal-Tron, traveled to National Harbor, Maryland, a suburb of Washington DC, to receive the award.  An evening reception and an awards luncheon were held at the Gaylord National Resort & Conference Center.

Cal-Tron has a long history with Northrop Grumman.  They began molding parts for Litton Guidance and Controls in Woodland Hills, CA, in the early 1960’s.   Northrop purchased Litton in 2001 and the business relationship continued.  Clarence Pool, founder of Cal-Tron Corporation, was an acquaintance of Jack Northrop, founder of Northrop Grumman.  Back in the late 1930’s, Clarence worked for Douglas Aircraft and was occasionally sent over to Northrop to help out as needed.  This was a pivotal time in aircraft history with many advances being made.

Over the years, Cal-Tron has received various awards from their suppliers.  They were part of the original General Dynamics Supplier Advisory Board and were instrumental in implementing Statistical Process Control (SPC) within the General Dynamics system and supplier base.  They have received awards and/or special certification from Aerojet Rocketdyne, General Dynamics, Hughes Missile Systems, Sargent Aerospace and Shurflo, to name a few.  In the late 1990’s they were nominated for the SBA’s Small Business Of The Year and received the U.S. Small Business Administrator’s Award For Excellence.

In early 2013, Cal-Tron began the process of becoming ISO 9001-2008 certified.  The International Organization for Standardization (ISO) created a standard which aimed to harmonize quality management processes in manufacturing from a global point of view. Over time, the success of the ISO 9001 series led to the introduction of industry-specific standards, setting the table for applying quality management across a broad range of industries, such as the aerospace and defense industries.  Cal-Tron received their three-year certification in July, 2013.  Each year they go through an on-sight audit done by a specially accredited outside agency.  Every three years an extensive on-sight audit is completed to obtain the three-year renewal.  Cal-Tron’s next audit is coming up in May, 2016.

Cal-Tron Corporation is a local, family owned business that moved to the Eastern Sierra in April 1970.  The business was started in the Los Angeles area in the early 1940’s.  Ms. Leatham and Ms. West are the 4th and 5th generations to be involved in the business.  Their website is:  www.caltroncorp.com
