SOLKOTE™ is both thickness and substrate dependent. Ideal optical qualities for solar thermal applications are best achieved by applying a thin coat on low emissivity substrates such as aluminum, copper or stainless steel. Emissivity can range from .28 - .49, and absorptivity from .88 - .94, depending on the substrate and thickness of the dried film. Passive applications on cementitious substrates will yield high absorptivities but only moderate selectivity. Thicker applications on metallic substrates will yield high absorptivities and excellent radiation properties for radiant heating applications.

SOLKOTE HI/SORB-II on stainless steel
AISI 304 Stainless Steel was dip-coated in SOLKOTE HI/SORB-II. After each coat, solar and infrared hemispherical reflectances were measured to calculate solar absorptance: a, and thermal emittance: e (400şC).
