How to Pick the Right FDA Acceptable Coating

A good amount of commercial food grade processing equipment comes “out of the box” with non-stick, FDA acceptable coatings applied to the appropriate machine mechanisms (learn why we say “FDA acceptable” and not “FDA approved” here).

As is with all new purchases, everything works great for a period of time. However, food ingredients can be surprisingly abrasive or acidic and coatings are not impermeable to wear, even the most robust ones.

Conversely, when the equipment does not come with a coating and sticking ingredients start impeding production for extended periods of time for cleaning, it is determined only after processing that one is needed.

In both instances, it is probably more cost effective to contact a local coating applicator to apply an FDA acceptable coating than it would be to contact the manufacturer for a replacement component or to have them locate an applicator.

However, it should be noted that there is no one cookie cutter FDA acceptable coating (no pun intended) that can solve every issue.

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:

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

Coated Dryer Panels

Case Study: Dryer Panel Coating

In a previous blog post, we discussed how functional coatings could be utilized to reduce downtime.

A prime example of such an instance is the case study of how DECC utilized a reinforced, non-stick coating to help solve a huge headache for the commercial healthcare laundry industry.

Healthcare laundry facilities have the laborious task of sorting plastic out of the linen prior to washing – this includes latex gloves, EKG stickers, tubes of ointment, ink pens, etc. No matter how many people are staffed at the front end for sorting, some plastic still inevitable makes it in the wash.

And if it makes it into the wash, it makes it into the dryers…where it melts and sticks. After time (in some instances, only a few months), a fresh clean dryer can become so clogged with melted plastic that it looks like below.

The Limitations of Rack-Spray: Unfortunately, it isn’t for all components

The DECC Company’s goal is to be the go-to resource for all of our customers’ functional coating application needs. In that regard, we understand that we cannot be everything to every customer. As a result, we sometimes have to turn work away and refer it to a dip-spin competitor.

Why? Because for certain part geometries, it is the only processing method that is suited for that particular component. As much as we make the case that certain components should not be processed in a bulk method, there are many instances in which a part should not be processed via a rack-spray application.

Dip-spin Snap Ring

Case Study: Rack-Spray When You Can’t Dip-Spin

As DECC is an exclusively rack spray coating applicator, we refer a good amount of work to dip-spin applicators. If we receive an RFQ for a part geometry that lends itself to a bulk application, we will not provide a quote without first sending them to a dip-spin applicator. We want current and potential customers to get the best price possible and a rack spray process is almost always more expensive than a dip-spin process…up front.

However, we also receive a good amount of new work from customers that have sourced with a dip-spin applicator on a part that should not be coated in a bulk method and, as a result, were experiencing significant quality issues.

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.

Full Film Properties & Cure

In our last blog we discussed the criteria of what makes a coating functional, which is when a coating has performance characteristics that go above and beyond being just decorative or protective. In order for a coating to perform at is highest intended level, it must be processed to ensure it exhibits full film properties.

Coating manufacturers design coatings to do some pretty amazing things when you consider how thin they are applied (typically a mil or less for the coatings DECC sprays). However, if they are not applied and processed in accordance to the PDS (Product Data Sheet), the manufacturer will not guarantee performance. Probably the most important step to guarantee a coating’s performance is to ensure the proper bake time and temperatures have been achieved during cure.
