  • Acrylic Powder Uses?

    I received my Acrylic powder today and polished up a piece of aluminum 2" pipe and shot it. Looked almost 99.99% as good as it did polished. Maybe Better! Clear stuff it is.

    I wanted it to use on my new polished 350 intake and looks like its the ticket for protecting the aluminum. Years ago we only could use auto grade clear and it would have some heat issues on an intake but seem to be ok on valve covers.

    Can acrylic go over other powders? If so what type? I am having trouble searching for the info I want and thought one of you might have some answers?

    I know Jason has messed with it and Todd has but not sure who else has and Todd can't tell any one any thing right now!!!!!!!! Hope he can latter

    Big Duke Nukem,


    Here you go.

    Acrylic powders provide excellent exterior durability. Common acrylic based powder coats include urethane acrylics, acrylic hybrids, and glycidyl methacrylate (GMA) acrylics.

    Urethane acrylics require cure temperatures of 182C. They offer excellent thin film appearance, good chemical resistance and hard films. Flexibility and impact resistance is usually poor. GMA acrylics can be cured in less time or at lower temperature than the urethane acrylics, and they also can provide superior weathering characteristics. They make excellent clear coats over brass or chrome. Like the urethane acrylics, flexibility is somewhat limited. Acrylic hybrids combine the acrylic resin with an epoxy binder. They are somewhat better than a polyester-epoxy hybrid but still not considered acceptable for exterior use. Acrylic hybrids generally have much better mechanical properties than the other acrylic powder coats.

    Because of their good appearance, tough surface, exceptional weatherability, and excellent electrostatic application characteristics, acrylics are frequently used for application to products that have very high quality standards. For example, development is being conducted to determine the suitability of acrylic powder coating as a clear coat on automotive bodies.

      So cure around 360 using a light coat and not heavy like powder and I should be at what I want as for as keeping it all looking like new?

      But can it be put over say chrome powders or is it just for use over other type products? Or have I got to do the testing myself? That I can do as long as it doesn't take take years to see what it does if it works on the first go a round! I ant not spring chicking no more!

        Ahhh ...I am understanding your question now.

        Follow the cure schedule PBTP gives you. Also mixing powders you need to call PBTP to get their feedback on what you are doing.

          I have been told to be careful and make sure I clean up real well when using acrylic so that I don't cross contaminate any of the other powders and that why I was wondering if it would say topcoat a chrome powder or another color that you need to clear?

          I can try it but if someone says it want work because they have tried already then I want have to.

          Maybe they will pipe in today and give a answer? What about it Mat or Shelly or your tester fellow in GA.

            You can apply the acrylic over chrome or any other color we carry. You want to apply a thinner acrylic coating because too much film build up will cause the surface to crack. You must cure the base coat completely before applying the acrylic topcoat. I do know of guys that are curing the basecoat and letting air dry. Then they are re-heating the part back to about 120-150F, and finally applying the acrylic clear. Maybe Auto-Cycle has some input on this.

                  Most people that say it doesn't work is because they are hot flocking over undercured powder.
