Overview
• Ashland and Michelman have partnered to develop water-based barrier systems (WBBS) for paper and paperboardbased barrier systems (WBBS) for paper and paperboard packaging
• A novel "base coat" for WBBS was recently developed and• A novel base coat for WBBS was recently developed and validated in several grades of paper and paperboard
• Improves water, oil and grease resistance and reduces moisture vapor transmission rate of WBBS
• Performs better and costs less than other technologies and offers a number of environmental benefits

Overview of Novel Base Coat for WBBS
• Ready-to-use product serves as a low-cost "primer" (2-4 g/m2)
• Applied at the size press or coater
• M difi d i th f t h f• Modifies and improves the surface topography of paper and paperboard without sealing
• Holds more expensive top coat at surface• Holds more expensive top coat at surface
• FDA-approved formulation is a patent pending combination of mineral binder and cationic crosslinkercombination of mineral, binder and cationic crosslinker
• Marketed as Dimension™ BC1060 converting additive

Benefits of Novel Base Coat for WBBS
• Improved water, oil and grease resistance
• Reduced moisture vapor transmission
• Reduced cost of total barrier package• Reduced cost of total barrier package
• Reduces or replaces wax and polyethylene coatings
• Eliminates the use of fluorocarbons
• Allows for the increased use of renewable materials and improves the ease of recycling
