What are Dyna-Tek’s non-stick coatings?
Why should you choose Dyna-Tek products?
The BEST solution for controlling adhesion build-up starts with our patented hydrophobic coating technologies. Ultimately, the BEST solution is the one that can be controlled by the Converters.
How do they work?
Dyna-SLICKSHIELD and Dyna-SLICKSHIELD PLUS, as their name implies, creates a sealer base coat that “shields” the surface of your parts. Dyna-SLICKSHIELD and Dyna-SLICKSHIELD PLUS are hydrophobic and create a very good corrosion resistant bond and seals the porosity of the substrate.
Dyna-SLICK PLUS is an outstanding anti-adhesive coating. Dyna-SLICK PLUS forms a covalent (chemical) bond to Dyna-SLICKSHIELD and Dyna-SLICKSHIELD PLUS which means they will not delaminate from each other.
When needed, another coat of Dyna-SLICK PLUS can be applied over the previous coat to refresh the non-stick properties again.
What is recommended for cleaning the dies before applying Dyna-Tek products?
Ultimately, there isn’t a coating formulated and sold that will perform the way it was intended if the surface preparation is not good. So, overlooking and taking the surface cleaning steps of your dies for granted will often lead to underwhelming results.
- DO NOT use petroleum-based solvents such as lacquer thinners or mineral spirits. These solvents will deposit oil-based residues in the pores of your dies which will interfere with Dyna-Tek’s coatings being able to adhere to the surface/substrate.
- You can use acetone, denature alcohol or isopropyl alcohol (IPA) solvents, however because these solvents tend to flash-off quickly, they are not as effective for cleaning any impurities in the porosity of the substrate.
- Cleaning solvents we have found to be very effective are either Tert-Butyl Acetate, aka TBAC, or Isopropyl Acetate. We lean towards TBAC for a couple reasons:
- VOC-exempt by the EPA. Suitable for use anywhere in the U.S.
- Slower flash-off (evaporation time), which makes it better for deeper cleaning of the substrate.
- Thoroughly vetted by the Army Research Laboratory in 2010. Army Report
- TBAC - Safety data documentation – Dyna-Prep SDS
- You can purchase TBAC from a wide range of sources. We offer TBAC in 4, 8, 16 and 32 ounce containers.
Are the coatings thick?
No, our coatings are as low as 1 Micron to as high as 12 Microns thick.
How are they applied?
You can use a variety of tools to apply the coatings. From cotton tip swabs, microfiber sponge pads and lint-free cotton cloth. See application tools for sale.
What is the temperature resistance of Dyna-Tek’s coatings?
- Dyna-SlickShield™ - 1000-1200° F.
- Dyna-SLICK™ - up to 800° F.
Where are the coatings used?
- Die-Cutting (Converter) industry
- Outdoor Sporting Goods industry
- Aerospace industry
- Industrial Coatings
How long does it take the coatings to cure?
The simple answer is 60-90 minutes. Variables that can slow down the cure time are:
- Temperature. If the room temps are below 60° F, this can slow down the cure somewhat.
- Humidity in the air. The curing catalysts for Dyna-Tek coatings are oxygen molecules and moisture in those molecules. So, drier air can influence the final cure time. For example, you might see your same application methods that work great during warmer summer months but need a little more time in the drier winter months.
How should you store Dyna-Tek coatings?
The shelf life of any of our products is 1-year from purchase, provided:
- The container is stored in 55 – 70° F environment.
- The container is not exposed to sunlight; even through UV protected windows.
- The bottle hasn’t been left open. Once the bottle has been opened, you should be vigilant about closing the cap when not using it.
