01. What is NL-19®?

NL-19(SM) is a proprietary surface treatment that Foreverbolt has a partnership with. The surface treatment alters the surface and prevents corrosion. The net gain is NL-19(SM) surface treatment will not rust or corrode like non-treated stainless steel. NL-19(SM) surface treatment creates a boundary layer against the elements, thus resulting in less surface contamination which means less maintenance.

03. If you bend or form the material are you exposing the outside area to more corrosion?

There will be some slight exposure, but nothing significant.

04. Now in the field if the surface gets damaged or nicked what can you do?

If the raw materials are chipped or broken they will be exposed to the environment, they will have to be processed again. There is currently no way to spot process small pieces in the field. However, we ensure minimum damage while in transit.

05. Who’s your competition and what is the cost?

Currently there is no competition and the cost varies based on the project size and per piece count. Typoically the cost is 20 to 30 percent higher than non-treated stainless steel.

06. Is your process an all chemical process?

There are some chemical steps in the process, but there are also a variety of other “proprietary” steps involved in creating a final product. In total it is a complicated 19 step process that we have developed over the last 15 years. We profess that we are making a truly green product.

07. Have you had any failures?

The product is guaranteed for life, (see disclaimer) provided there is no damage to the pieces, there have not been any reported failures in the past 15 years of using this process or early iterations of the process.

08. What’s the cure time?

Once the process is complete it is done, there is no cure time.

09. Is your process chemically inert?

The process is totally inert. And we have preformed many tests, even out gassing is nonexistent.

10. Does it bleed or leech into the environment?

The process is completely clean and nothing will leach into the environment.

11. Does the coating ever get stripped from the surface say when you’re tightening a nut?

Galling will happen if the fastener is over torqued, however this process will reduce the galling significantly. By adding white lithium grease or WD-40 it will help considerably.

12. So do you have to use any spray lubricant?

It is not mandatory, but can be used to significantly reduce galling.

13. Does NL-19® affect the adhesion properties with regard to concrete…

We have not seen any advantage or disadvantage to using NL-19® with rebar and concrete.

14. Does your product work on couplers?

As long as it is a stainless steel product, yes NL-19® can be applied

15. Can your product be applied in the field?

No, it has to be processed in house.

16. Will you have any options for colorization or sheen?

Yes we can treat the finished processed surface to look duller with no shine. It can be powder coated or painted like any other metal surface at an additional cost.

17. Will powder-coating make it last longer?

Yes, in general, if done properly it can increase the life of the material significantly. This is a loaded question because power-coating is a process that needs to be controlled and done correctly.

18. Can it be brushed?

Yes, NL-19 surfaces can be brushed with scotch brite or a similar type of scuffing material. Do not use steel wool, it will impart contaminates which will contaminate the processed surface.
