NextStar # 105 Hydrophilic PolyUrethane Foam

NextStar 105 is a hydrophilic two-component, NON-FLAMMABLE VOC compliant polyurethane injection resin designed to control water and to seal moving, non-structural cracks in concrete. When mixed, the two-component system does not require additional water to foam within 30 seconds of passing through a static mixer. The components of NextStar105 expand and quickly cure to a flexible, closed cell foam. It is better suited for tight cracks.
NextStar 105 is formulated TDI free.
NextStar 105 cures to tough, adhering foam capable of withstanding thermal cycles and crack movement. It is offered in 450ml. dual cartridges.
NextStar 105 is also available as a one-component system utilizing the moisture in the crack for foam expansion.
As one component, it is available in various containers. More consistent and predicable foam formation and properties are attained when utilized as a two-component system.

PHYSICAL PROPERTIES (AS A 2-COMPONENT SYSTEM)
• Tensile Strength (ASTM D 3574-86) 380 PSI
• Tensile Elongation (ASTM D 3574-88 400%
• Bonding Strength 150-300 PSI
• Shrinkage <5%
• Flash point (of uncured components) 225ºF

Quantity to use: It is difficult to determine the amount of material to adequately seal a given crack. Experience in
home foundation cracks (8’ long with a wall thickness of 8-10”) suggest the usage of 10-21 ounces of # 105 per 8’ crack (versus an average of 30-50 ounces of epoxy). Th us, while 105 can theoretically foam to
4-5 times its volume (more typical is 2-3 times), its unfoamed volume for small cracks (1/32 - 1/4”) as oft en found in foundation cracks.

Application
