| description | A moisture curable hot melt sealant composition that includes a silane-functional polyurethane that is free of isocyanate groups, a thermoplastic elastomer having a weight average molecular weight of at least 100,000 grams per mole and being derived from 0% by weight to no greater than 30% by weight styrene, based on the weight of the thermoplastic elastomer, the thermoplastic elastomer being selected from the group consisting of butyl rubber, ethylene-propylene rubber, ethylene-propylene diene rubber, thermoplastic polyolefin elastomer, styrene block copolymer, and combinations thereof, a first tackifying agent that includes from 0% by weight to less than 15% by weight aromaticity based on the weight of the tackifying agent, the first tackifying agent being selected from the group consisting of aliphatic tackifying agent, aromatic-modified aliphatic tackifying agent, cycloaliphatic tackifying agent, aromatic-modified cycloaliphatic tackifying agent, and combinations thereof, a liquid butene component selected from the group consisting of polyisobutylene, polyisobutene, polybutene, and combinations thereof, and optionally a second rosin-based tackifying agent. |
