将萨兰树脂F-220（Dow Chemical Company）以1：4至1：8的树脂：溶剂比溶解在甲基乙基酮中，用于涂覆天然土壤土块。这些未受干扰的样品，然后用于确定土壤性质，如体积密度在不同的水分条件下，保水性，和收缩膨胀特性。它们也用于显微镜研究。作为涂层材料，萨兰比石蜡有几个优点。该萨兰溶液在田间使用方便，涂层坚韧、柔韧，在用于测定土壤含水量的温度下不熔化。
Saran Resin F-220 (Dow Chemical Company) dissolved in methyl ethyl ketone in resin: solvent ratios of 1:4 to 1:8 is used to coat natural soil clods. These undisturbed samples are then used to determine soil properties such as bulk density at various moisture conditions, water retention, and shrink-swell characteristics. They are also used for microscopic studies. As a coating material, saran has several advantages over paraffin. The saran solution is convenient to use in the field, and the coating is tough, flexible, and does not melt at temperatures used for determining soil water content.
