NF 205 RTV Silicone Gasket Maker

NF 205 RTV Silicone Gasket Maker

 

Product Description

 

NF 205 RTV Silicone Gasket Maker is a high-performance silicone sealant developed for sealing, bonding, and repairing works where heat resistance is required. It is an ideal sealant for high-temperature construction applications. It reacts with atmospheric moisture to produce a tough, elastic silicone. NF 205 has excellent heat resistance after curing up to 250 °C permanently and up to 300 °C temporarily. It is a 100% silicone, acetoxy cure, RTV silicone. This sealant has a fast cure and high strength. It resists mechanical enforcement after curing. NF 205 remains flexible at low (-40 °C) and high (+250 °C) temperatures. It will not crack, shrink, or become brittle. NF 205 is a one-component sealant that conforms to the requirements of VOC content specifications in LEED credit EQc4.1 “Low-emitting products” of SCAQMD rule 1168.
