NUKOTE ST® is NCSI’s multipurpose high performance polyurea designed and developed to perform well for anticorrosion and waterproofing applications on steel, concrete, and many other substrates. ST is a two-component, 100% solids, pure polyurea that significantly reduces the moisture problems that commonly cause pinholing and blistering in most polyurethane, polyurethane-hybrid and other organic coating systems.
Nukote ST-M is a pure polyurea used where faster gelling time is desired to minimize outgassing and the resultant pinholes, excess sagging and for overhead applications.
Nukote ST-PW is an ANSI/NSF 61 compliant and approved pure polyurea barrier material and also conforms to global migration Standard US – FDA: 21 CFR 175 – 300. Nukote ST-PW is tested and approved by many countries for applications on substrates in contact with potable water and food products.
These aromatic polyurea elastomers display good chemical resistance, thermal stability and UV resistance. The Nukote ST series can be textured easily for anti-skid purposes. These products have very good moisture permeation resistance and perform as an excellent barrier coating. They also provide excellent adhesion to most substrates when used with a suitable Nukote primer.
