Adiacoat Elastomer Coating

Adiabatics Technologies has been involved in research and development projects focused on the development of wear-resistant coatings for a range of applications. Most have utilized traditional thermal/flame sprayed coatings or thermal bonded ceramic coatings developed in-house. In 2004 we embarked on developing polymer coatings for thermal insulation and friction and wear applications. Polymer coatings proved to be much more cost effective for low temperature applications due to higher application efficiency.

In river systems, sand and sediment comprise a substantial volume of the water flow. This high solids content results in severe abrasive erosion on internal impellers and water pump housing.

For these applications, we developed a hybrid polyurea elastomeric coating to resist sediment erosion/abrasion and cavitation for water pumps.

It is clear that elastomeric coatings absorb the energy imparted from impingement of fine particles on the surface of the pump impeller and housing in critical areas. Adiacoat coatings have a greater ability to absorb the pressure waves generated during cavitation.

Laboratory tests show the Adiacoat coating has the potential to protect the pump impeller for over 20 months as compared to 8 months for tungsten carbide. The Adiacoat coating is not like a typical epoxy coating; it will outperform even the tungsten carbide standard.
