    摘要: A sealant composition for use in two-pane or multi-pane insulating glass or solar modules, the sealant composition including: a) an olefinic polymer having a number average molecular weight from about 100 D to about 700,000 D, preferably from about 100 D to about 300,000 D; b) a modified olefinic polymer; c) a fine-particle inert filler; d) at least one of a desiccant and a water scavenger, and e) an aging resistor. The sealant composition has a tensile strength greater than 20 PSI, preferably greater than 50 PSI, a lap shear strength greater than 20 PSI, preferable greater than 40 PSI, and the tensile and lap shear strengths balanced such that the sealant fails cohesively before failing adhesively.
