Nitoseal PU40 is a one part, low modulus gun grade elastomeric sealant based on polyurethane technology. Nitoseal PU40 may be applied to joints between 5 and 35mm wide. To minimise stress imposed on the joint sealant, all moving joints should be designed to an optimum width to depth ratio of 2:1 with an overriding minimum depth of 5mm for non-porous surfaces and 10mm for porous surfaces.

Advantages

• Adhesion to most common building materials
• Single component with fast rate of cure
• Easy to apply
• UV resistant
• Primerless for most applications (see “Priming”)
• Available in a range of colours
• ISO11600:2002 Type F 25LM compliant
