TremPro 644 Silicone Sealant # 0160297 is similar to Dicor lap sealant. I can't say exactly what the formula is for Dicor but I can tell you that TremPro 644 is a silicone sealant used in numerous applications including the installation of RV and trailer roof vents.

Both products adhere to rubber-like roofing materials, aluminum, galvanized metal, plastic, vinyl, fiberglass, wood, and even mortar and concrete and are compatible with EPDM and TPO roof coverings so the two products are comparable.
