With the diversity and complexity of body structure of automotive, traditional PVC sealant is unable to meet all the structural sealing requirements. To solve the PVC sealant cracking problem, used on body joint seam, a modified silyated polymer sealant was introduced in this paper. The tensile and shear strength of the sealant, before and after artificial weathering and hot-humid aging, were studied. The results show that the effect of the aging test on the properties was limited, and no cracks occurred after the road duration test.
