One-component, elastomeric, gun-grade polyurethane sealant

MasterSeal NP 1 is a one-component, high performance, non-priming, gun-grade, elastomeric polyurethane sealant. It requires no mixing and typically requires no priming to bond to many materials, including concrete and masonry.

PRODUCT HIGHLIGHTS
* One-component formula requires no mixing, helping to reduce labor costs
* Joint movement capability ±35% provides excellent flexibility for keeping moving joints weathertight
* Easy to gun and tool, speeding up application and making neater joints
* A vailable in ProPaks, reducing jobsite waste, lowering disposal costs
* 12 standard colors to match a wide variety of common substrates
* No primer required for most construction materials lowering installation costs
* Weather resistant for long-lasting weathertight seals
* Wide temperature application range makes MasterSeal NP 1 suitable for all climates
* Compatible with non-rigid coatings and can be painted
* Superior holding power for long-lasting roof tile installation
* UL listed; Passes 4--hour, 4--inch, fire and hose stream test when used with Ultra Block or mineral wool
* Suitable for water immersion with documented performance in wet areas
* Meets VOC requirements in all 50 states

IMPORTANT INFORMATION

For Best Performance
* Do not allow uncured MasterSeal NP 1to come into contact with alcohol-based materials or solvents.
* Do not apply polyurethane sealants in the vicinity of uncured silicone sealants or uncured MasterSeal NP 150TM.
* M asterSeal NP 1 should not come in contact with oil-based caulking, uncured silicone sealants, polysulfides, or fillers impregnated with oil, asphalt or tar.
* Protect unopened containers from heat and direct sunlight.
* I n cool or cold weather, store container at room temperature for at least 24 hours before using.
* When MasterSealNP 1 is to be used in areas subject to continuous water immersion, cure for 21 days at 70° F (23° C) and 50% relative humidity. Allow longer cure times at lower temperatures and humidities. Always use MasterSeal P 173.
* Do not apply over freshly treated wood; treated wood must have weathered for at least 6 months.
* Do not use in swimming pools or other submerged conditions where the sealant will be exposed to strong oxidizers. Avoid submerged conditions where water temperatures will exceed 120° F (50° C).
* Substrates such as copper, stainless steel and galvanized steel typically require the use of a primer; MasterSeal P 173 or MasterSeal P 176 is acceptable. For Kynar 500 based coatings, use P173 only. An adhesion test is recommended for any other questionable substrate.
* MasterSeal NP 1 is an aromatic urethane, as such it may discolor over time with UV exposure. Where maintaining a true white appearance is critical, use MasterSeal NP 150 or MasterSeal CR 195 sealants.
* MasterSeal NP 1 can be applied below freezing temperatures only if substrates are completely dry, free of moisture and clean. Contact Technical Service for more information.
* L ower temperatures and humidities will extend curing times.
* Pursuant to accepted industry standards and practices, using rigid paints and/or coatings over flexible sealants can result in a loss of adhesion of the applied paint and/or coating, due to the potential movement of the sealant. However, should painting and/or coating be desired it is required that the applicator of the paint and/or coating conduct on-site testing to determine compatibility and adhesion. Proper application is the responsibility of the user. Field visits by BASF personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.
* Not for use in glazing applications. Do not apply on glass and plastic glazing panels.
