Use of Soltex Polybutene in caulk and sealant applications is advantageous because:

• Plasticizer effect increases sealant flexibility.
• Tackiness results in a soft, easily extruded sealant.
• Reduced use of solvents provides environmental benefits.
• Improves adhesion and aging.
• Low moisture transmission.
• Lower oil-to-filler ratios.
• Extruded onto tape.
• Minimizes shrinkage after application.
• Polybutene functions in a caulk as a primary vehicle to bind and wet the fillers, thereby improving the flow characteristics.
