Custom Coating Through the Eyes of an Intern

I am currently an engineering intern seeking to earn my degree next spring. I started working for the DECC Company in the beginning of 2016 and the only prior experience I had in the coating industry was when I used a can of peelable spray paint on my rims to cover up some rust spots.

In my brief one and half years at DECC, I can sum up what I’ve learned about the coating industry in three simple sentences: Continue reading Custom Coating Through the Eyes of an Intern

Tight Tolerances

Functional Coatings and Tight Tolerances: No Need to Worry About a Costly Redesign

Producing quality product within a specified tolerance is a battle that every manufacturer, in every industry, fights every day.

Design engineers have the task of determining how tight of a tolerance should be allowed when developing a part and usually operate in the mind set of “the tighter the better.” In some cases, unnecessarily tight tolerances just drive up the cost of a component unnecessarily, but that is a debate for a different day.

It is understood that a component designed to need a functional coating would have its tolerances accordingly compensated. However, if the component you’re dealing with Continue reading Functional Coatings and Tight Tolerances: No Need to Worry About a Costly Redesign

Corrosion Protection: Sacrificial vs Barrier Coatings

Corrosion is one of the leading causes of component failure across all industries. In terms of functional coatings that offer corrosion protection, there are essentially two categories: sacrificial coatings and barrier coatings.

The type of corrosion being combated, as well as if there are additional performance criteria that the coating must achieve, will help determine which type of coating system you should use.

First, an explanation of the two categories:

Dry film lubricant

How to Choose the Right Dry Film Lubricant for Your Application

As there is a vast array dry film lubricants on the market, there are just as many different applications in which these coatings could be utilized.

Given the countless combinations of coatings and applications, determining which one would be best for your application can be a daunting task. However, by determining a few key variables, the options can be scaled down considerably.

When trying to decide which type of dry-film lubricant would be best for your application, the following should be considered:

Rack Spray vs Dip Spin Infographic Header

Infographic: The True Cost of Dip-Spin vs Rack-Spray

Simply put: there are part geometries that lend themselves to a dip-spin coating process and those that do not.

In fact, even though DECC is a rack-spray facility, we will be the first to direct a customer to a dip-spin competitor when asked to quote a part that is suited for such an application. A rack-spray process can be two to three times more costly than a bulk process and, when it makes sense, we want our customers to take advantage of such pricing.

However, for part geometries that are not suited for dip-spin, quality and delivery issues quickly negate any “savings” when the true cost of processing is evaluated.

Rack-Spray and the Dreaded “Bare Spot”: Don’t Let This Be a Deal Breaker

One of the fears associated with a rack-spray coating process is that, due to the part being “fixtured” and resting on a hook, the part will not have complete coverage. And without complete coverage, the functionality of the coating is in jeopardy.

It is technically true that there will be a “witness mark” where the part is held on the fixture.

However, in regards to the “functionality” aspect of the coating; it depends on what the customer’s perception of “in jeopardy” is.

For example, below is how a typical witness mark on all rack-sprayed parts would look like. For reference, the hole this was racked thru is 8.5mm in diameter.

3D Printer Making Coating Mask

Need Coating in Some Areas and Not Others? Here are Five of the Most Common Masking Types

When needing a functional coating application, most components require complete coating coverage on the entirety of the part. When there are instances where this is not the case – such as cosmetic, fit or function implications – masking of certain areas of the part is necessary.

If an area of a part must be masked, there are a variety of options depending on component geometry, mask location and cure temp of the coating being applied.

Below are the five most typical types of masks used by coating applicators, particularly  Continue reading Need Coating in Some Areas and Not Others? Here are Five of the Most Common Masking Types

Washer with Xylan

Xylan Coatings: High-performance Fluoropolymers for Function in Extreme Conditions

We have discussed in a previous blog post how DECC is “coating agnostic” and will often times provide samples with multiple coatings – from different manufacturers – for our customers to validate performance.

Most often times, if a dry-film lubricant is needed, a coating from Whitford’s Xylan series is one of those options.

Xylan is a high-performance fluoropolymer coating. Fluoropolymer coatings contain low-friction, dry-lubricant materials suspended in a plastic binder. The plastic binder, which Continue reading Xylan Coatings: High-performance Fluoropolymers for Function in Extreme Conditions

DECC Est. 1964

Dependability and Expertise: Why DECC’s Culture Sets Us Apart

A relatively recent survey conducted by Thomasnet.com asked buyers, engineers and procurement professionals what factors they deem most important when selecting new suppliers.

“Delivery Performance” and “Experience in Your Applicable Industry” were the number one and two most critical factors for evaluating a supplier.

For the past five years, DECC has maintained an over 99% on-time delivery rate. But more so, what sets us apart from our competition is our passion to be a resource for our customers and help them solve their respective challenges with a team that has decades upon decades of experience in the coating industry.

Meet the culture at DECC in our newest company video here.

Use Your Coating Applicator for Preventative Care, not Urgent Care

Minus components exposed to the elements that will always need some sort of corrosion protection, applying a functional coating to an automotive component is something most OEMs would prefer to avoid as it adds cost and extra processing steps.

However, as with the case with component performance/warranty issues, these parts were designed with the intention of not needing a functional coating as a solution or it would have been specified to begin with.

This is where the Preventative Care/Urgent care analogy comes into place.
