Polyurethane systems marked by E&K are based on one-component binders, which are moisture curable, and are two components of polyurethane systems. These two separate components, known generically as polyols and polyisocyanates, generate an exothermic or heat-releasing reaction when mixed to form solidified polyurethane-based products. A polyol is a chemical compound containing more than one alcohol group, which is capable of cross-linking with other compounds in order to form polymers (chemical compounds with repeating structural units).


A polyisocyanate is a chemical compound consisting of carbon, nitrogen, and oxygen atoms, which also has the capacity of cross-linking with other chemical compounds, including polyols and amines, to form polymers, such as polyurethanes and polyureas. E&K uses aromatic and aliphatic diisocyanates in the formulation of its polyurethanes. Blending diisocyanates and polyols in certain ratios result in various distinct polyurethanes used in the manufacture of numerous finished products. The specific ratios in which these chemicals are blended and certain additives are added to the basic chemicals (which include chemical catalysts and pigments) constitute what the Company considers to be proprietary technology or trade secrets.


The physical properties of polyurethane and polyurea products may vary from soft foam to a hard solid depending on the relative proportions of polyols, amines and polyisocyanates used in their production. The polyol and polyisocyanate components must be stored separately and then blended in specific ratios to yield optimum characteristics in the finished product.


E&K's chemical systems fall into eight general categories, based on the type of material formed by reaction of the systems: (i) polyurethane elastomers, (ii) flexible foams, (iii) rigid foams, (iv) rigid insulation foams, (v) puhybrid, (vi) polyurea, (vii) epoxy and (viii) plastisol, and (ix) Fire Quencher for PFP coatings.
