Prime Resins Unveils Inorganic Mineral Coating for Lining, Fire and Corrosion Applications

Prime Resins Inc. has introduced a new class of inorganic water- and mineral-based coatings that provide corrosion and fire resistance protection on multiple surfaces.

Prime Coat 6000 Lining, Prime Coat 6100 Fire and Prime Coat 6200 Corrosion are spray-applied sustainable inorganic coatings with broad applications. Each offers zero VOCs. All three are designed to have a rapid set time and cure tack-free within five minutes.

Prime Coat 6000 Lining is proven to meet NSF/ANSI 61 standards for contact with potable water and is highly abrasion- and chemical-resistant, making it an option for municipal water and sewer applications, water tank linings and the like. 

Prime Coat 6100 Fire provides superior fire resistance protection when applied to a variety of surfaces. ASTM E84 testing proved zero flame spread, zero gas generation and zero smoke generation.

The flame spread protection provided by Prime Coat 6100 Fire is remarkable. In additional unofficial testing to observe the product in an actual setting, two walls of a house scheduled to be burned down as part of local firefighter training were sprayed with Prime Coat 6100 Fire. Remote cameras installed captured the fact that these two walls were literally the last parts of the structure left standing even though firefighters repeatedly tried to engulf them by heaping burning pallets and straw bales against them.

Prime Coat 6200 Corrosion provides durable protection against corrosion and oxidation of concrete and steel surfaces. Only a thin layer, less than 20 mils, provides corrosion protection. The product develops a strong bond with properly prepared surfaces, producing an alloyed layer that remains bonded to the surface even if the visible layer is penetrated.

This product is ideal for marine applications such as seawalls, bridges, rebar, railcars, pipelines, tanks and other surfaces exposed to moisture and/or abrasive substances. It is highly chemical- and abrasion-resistant. The life of concrete that is starting to erode and shed aggregate can be extended by many years with a thin application of Prime Coat.

A new pump has been developed for these products. The Prime PC features twin progressive cavity pumps to meter and disperse the material with almost no shearing. Fewer passes are needed to build thickness since the material does not require over-diluting to prevent shearing, which is typically the case with piston-style pumps.
