Blackhawk™ 5900 Series Additives

The Blackhawk 5900 Series Additives include a range of oiled polymer additives designed to enhance the adhesion and tack properties of asphalt-based self-adhering membranes, self-adhering underlayments and waterproofing barriers, especially in lower temperatures.

Blackhawk 5900 Series Additives can also be used to modify SBS cap and base sheet blends to improve polymer dispersion, reduce mixing time and improve UV resistance and weatherability.

They remain liquid at ambient temperatures, and therefore can be easily pumped and blended with most types of molten bituminous compounds.

Features

• Increases adhesion in low temperature applications
• Extends shelf life of self-adhering membranes
• Minimal effect on softening point of the compound
• Easily pumped liquid at ambient temperatures
• Reduces viscosity of overall blend for ease of manufacture
• Improves polymer dispersion and reduces mixing time
• Minimal effect on penetration value
• Aids in film release at elevated material temperatures

Uses

• Self-adhered bituminous ice and water shield membrane additive
• Self-adhered below-grade bituminous membrane additive
• Self-adhered bituminous roofing underlayment additive
• Self-adhered bituminous waterproofing barrier additive
• SBS base and cap sheet blends
