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:

The Advantages of Being “Coating Agnostic”

In a previous blog post, we talked about solving essentially the same performance issue with two different coating types. This happens frequently and sometimes it involves using not only different coatings, but coatings from completely different suppliers.

As a privately held coating applicator not owned by a coating manufacturer, DECC can approach solving customer’s problems from a dynamic position of not being tied to any single coating or coating manufacturer.

Sometimes this involves something as relatively simple as applying a coating that is called out on a specification for a customer.

For instance, a relatively common specification on prints for General Motors is GMW3359.

Some Problems Caused by Automotive Lightweighting (and How to Fix Them)

In today’s automotive manufacturing age, lightweighting is a popular, albeit almost necessary, approach for automobile manufacturers in an effort to improve the fuel efficiency of vehicles. With lightweighting, vehicle designers look to replace the heaviest vehicle components, such as steel panels, frames and assemblies, with lighter counterparts, such as aluminum or carbon fiber pieces.

Not only will this provide improved fuel efficiency, which all OEM’s are struggling with in light of the Obama administration’s minimum MPG requirements, lightweighting also helps improve the handling and performance of the car, something consumers have come to expect.

Bracket with zinc flake coating

Zinc-Flake Coating

Over 80% of the requests we receive from current or potential customers deal with the application of coatings to combat corrosion, be it environmental, chemical or temperature related. However, of these requests, the majority are environmental and can be solved with a zinc-flake coating solution. We will delve into ways to combat the other types of corrosion in another post.

What is Cyclic Corrosion Testing?

Cyclic Corrosion Testing 101

In the past several years, Cyclic Corrosion Testing, or CCT, has become a common practice in the automotive industry.

Designed to accelerate corrosion in a laboratory environment, CCT tests how materials used in the auto sector will react to the weather, stimuli, and conditions encountered on the road.This, in turn, allows manufacturers to prepare their materials accordingly, contributing to the longevity and durability of modern automobiles.

What is a Functional Coating?

What is a Functional Coating?

The tagline under our name on the homepage of our web site says that The DECC Company is “Your Functional Coating Application Specialist.” But what does it mean to say certain coatings are “functional” – aren’t all coatings designed to perform a specific function? Well…yes. However, there are certain attributes that set the coatings DECC applies apart from others.

Not Powder Coat, E-Coat or Plating

Powder coating, E-Coat (or electrodeposition coating) and plating all have different advantages and disadvantages dependent on their individual applications, but they all provide essentially the same one to two functions – cosmetic appearance and corrosion protection. Powder coat and E-coat look appealing and can provide 250 to 960hrs of corrosion protection, while standalone plating can achieve 240 to 720hrs…give or take depending on the type of plating.

However, the coatings DECC applies can have a variety of functions and, due to our spray method of application, are also cosmetically appealing. For instance:
