Frequently Asked Questions

1. Where can I purchase your industrial coatings?

ARC sells largely through a distributorship network. By providing a zip code or country, we can provide you with your local ARC distributor.

2. Where is the overcoat window on ARC products ?

The overcoat window for each product is provided in the Application Instructions found on the product pages of this website or by searching in the Literature Library.

3. When can I put the coating into service?

The coating can be placed into service based on the Full Chemical Cure noted on the Product Datasheet.

4. Is it advisable to add a solvent such as MEK to ARC coatings to increase the coverage and aid in ease of application?

No. The addition of solvents is not recommended and can actually damage the coating. The addition of solvent also voids the warranty.

5. What is surface profiling?

Surface profiling creates an anchor profile on the substrate. This anchor pattern actually increases the surface area and acts as adhesion points for the coating.

6. What type of sandblast media can I use?

This depends on the substrate. We usually recommend aluminum oxide or silicon carbide. Both of these media are hard and can provide an adequate profile of 3-5 mils. They also create less dust than some of the other media, such as Black Beauty.

7. Can I use steel shot to profile the surface?

We do not recommend using steel shot. This type of media can "peen" the surface (similar to a golf ball) and will not create the recommended rough angular surface profile of mineral based media (silicon carbide, aluminum oxide ).

8. Can I make the ARC material cure slower or faster by adding less or more curing agent during mixing phase?

No, not for the majority of the ARC line. Any of the novolac vinyl ester products (S7, NVE) can be accelerated or slowed by adding 15-25% more or less CHP (catalyst). All other ARC products have specific mix ratio and are pre-packaged to the correct mix ratio.

9. When I apply an ARC product on a cool day (50F-60F) how can I estimate the required cure time if the temperatures drops in the evening hours to 35-45F?

You can estimate cure times based on hardness development using a hardness indenter such as a Shore D scale. You should be looking for 60-70% of a products ultimate Shore D hardness as reported on the product data sheet.

10. How do I know if a product is supported by an approving agency such as US Navy, NSF or a multi-national corporations specifying agency such as MAERSK or Shell?
