Polyurea hard coating.Chemline has introduced CHEMTHANE 7050, a spray-applied, 100% solids seamless polyurea "hard coating" that is designed to protect Styrofoam or expanded polystyrene (EPS (Encapsulated PostScript) A PostScript file format used to transfer a graphic image between applications and platforms. EPS files contain PostScript code as well as an optional preview image in TIFF, WMF, PICT or EPSI, the latter being an ASCII-only format. ) architectural shapes from damage, including thermal expansion thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. , water intrusion, or direct impact. Applications include building accents, decorative columns, and exterior signage. A zero-VOC coating, it possesses 3,000 psi (20.5 mpa) tensile strength tensile strength Ratio of the maximum load a material can support without fracture when being stretched to the original area of a cross section of the material. When stresses less than the tensile strength are removed, a material completely or partially returns to its , 67 Shore A hardness, and 40% elongation elongation, in astronomy, the angular distance between two points in the sky as measured from a third point. The elongation of a planet is usually measured as the angular distance from the sun to the planet as measured from the earth. . For additional information, contact: www.chemline.net.
