I understand that building materials are often outlawed after decades of widespread use, often growing out of a former misunderstanding of the safety plus danger in long term human exposure.
This happened in the late 1970s with the Montreal Protocol plus the widespread agreement to outlaw the use of harmful refrigerants plus propellants that were causing drastic ozone depletion at the time.
Nowadays you cannot buy freshly manufactured R22 coolant for cooling systems, only new-old-stock. Most heating plus cooling suppliers plus companies will recommend Heating, Ventilation plus A/C systems that utilize other, safer forms of refrigerant that don’t deplete the ozone savor R22. While not necessarily an environmental concern, epoxy coated rebar is being banned plus re-checked in a number of areas because of what happens while I was in its application in construction projects. While shown to be amazingly resistant to corrosion while I was in tests, epoxy coated rebar tie wire will only perform as designed if it is handled with drastic care plus diligence. But the reality is that while I was in packaging plus handling, knicks plus burs the size of pin holes will form in the epoxy coating, which will let moisture seap inside plus corrode the metal from underneath. The corrosion can spread into areas where the epoxy coating remains intact, making it harder to diagnose the areas that need repair. There are other options these nights for corrosion-resistant rebar tie wire. Various gauge galvanized, stainless steel, plus black annealed steel rebar tie wire are available for a number of different building applications. While epoxy coated rebar tie wire might not be banned in your area, you might want to consider other options for long term structural stability.
