BASF MasterSeal NP 150 High Performance Low Modulus Hybrid Sealant - 10.1 Fluid Ounce Cartridge

MasterSeal NP 150, formerly Sonolastic 150 with VLM Technology, is a high performance, very low-modulus, high-movement, non-sag, fast-curing, hybrid sealant. Masterseal NP 150, formerly Sonolastic 150 with VLM Technology, provides superior adhesion results in a long-lasting bond. NP 150 is a low modulus to accommodate for joint movement (100% extension in EIFS joints with little stress on bond line). This polymer sealant can be painted with elastomeric coatings soon after installation and is easy to gun and tool which speeds up the application time. It can be used in a wide temperature application range and is weather resistant for long-lasting weathertight seals. Masterseal NP 150's fast curing helps to speed up jobsite production and its non-staining formula can be applied to stucco, concrete, aluminum, masonry, wood, stone, metal, vinyl, fiber cement siding and other sensitive substrates. Masterseal NP 150 is available in ProPaks (sausages) to reduce jobsite waste and lower disposal costs and meets all state and federal VOC regulations.

Limitations

• Not for use in glazing applications. Do not apply on glass and plastic glazing panels.
• Do not allow uncured sealant to come into contact with alcohol-based materials or solvents.
• Should not be applied adjacent to other uncured sealants and certain petroleum based products.
• Should not be used for continuous immersion in water.
• Do not apply over freshly treated wood. Allow six months for weathering.
• Do not use on nonporous surfaces such as aluminum, steel, vinyl or Kynar 500 based paints. Use MasterSeal P 173 on coated metals when testing dictates.
• Lower temperatures and humidity will extend curing times.
