VIDEO: Our QA Testing Is Why Pros Trust EMTECH For A Premium Finish

How do we formulate and test a EMTECH Waterborne Finish to ensure it performs to the premium standards we demand of it? We put each EMTECH coating through several phases of rigorous QA testing to determine how well they perform in specific types of in-house standardized tests. By doing this we can evaluate and adapt the formula to ensure performance continuity as we move from the R&D to the final production stage – and then out into the hands of our customers.

The video here shows the spray test phase (Phase 2) of our new product development–we’re spray testing some improvements to our EM7000HBL High Build Water-Based Spray Lacquer .

Phase 1 of QA testing is the blending of the selected water-based resins to see if they are compatible with one another and that they will blend together when using selected co-solvents and additives. Once this step is complete we then perform a series of durability tests to see if the cured resins perform as expected when run through a battery of physical and chemical tests. Only when the coating passes the first battery of tests do we then move on to Phase 2 of QA testing…

Phase 2 takes the formula to the lab spray booth–shown here–to test how it flows and levels when atomized through an HVLP spray gun. Once the formula passes this phase, it goes back to lab bench for a few more tweaks based on the initial physical and mechanical (i.e. spray) tests, and it’s off to the next round of performance reviews.

In Phase 3, we produce a pilot batch in the lab and send it to select customers for their review. It’s all very methodical–and a formula only moves forward into production once it passes each phase of QA testing entirely, and completely to our–and our customers’–standards.

So what are we looking for in the first spray test as shown in this video? Here are some of the attributes we’re looking at…

1. Atomization quality, or lack of it.
2. Wet film layout formation.
3. Inter-film air release.
4. Mid-dry-to-touch film formation and leveling.
5. Film formation qualities at the 1, 4, 6, 8 and 12-18 hour mark after initial film wet lay-down.

  1. I have some masking tape adhesive residue on my cabinets sprayed with emtec6000. What should I use for cleaning. Finish is fully cured

    1. Beth — Use a denatured alcohol diluted with water at 1:1. Gently rub the adhesive area with the tip of a cloth dampened with the water/dna solution. –JW —

    what is the best procedure and product to get a white bathroom vanity, plywood and hardwood construction. primer, top coat, cross linker?
    nozzle size needed to spray products

    1. Thank you for your inquiry. We recommend using the following Emtech products:
      1. HSF5000 Primer Surfacer
      2. EM6500 Pigmented Lacquer
      3. EM7000HBL Clear Lacquer (optional)
      4. CL100 Crosslinker (optional)

    Hi Jeff, I noticed that you are using a Fuji Q5 platinum HVLP turbine to spray the EM7000HBL through what I believe is the 1.3 N/N setup. While I realize that individual settings depend on numerous variables including temp/humidity, turbine stages etc., I’m curious, approximately how many turns or fractions of a turn (CCW from closed) did you open your fluid control knob in order to get the above results? Thanks

    Jeff O

    1. Jeff — You ask a thoughtful question, however, the answer depends on the size and distance of the part being finished. It really depends on how you want to control the fluid volume based on the variables of size, distance and pressur.
