ZJ-701 Fire Resistant Silicone Sealant

Description ZJ-701 fireproofing Silicone Sealant is a one-part, neutral curing ,fire-rated silicone sealant. It has an excellent adhesive ability to most construction materials without a primer. Characteristic It has Good features as follow: a. Can be easily used and extruded any time. b. Excellent thixotropic and extrusion ability, in any air temperature( -40oC to 100oC) can extrude easily. c. Neutral cure, no corrosive to most structural materials. d. When meet flame, it will not help to burn. Where to use It has excellent unprimed adhesion to a range of common construction substrates including stone,steel masonry,brick,wood,etc. It is ideal for weather-sealing of curtain walling, building facades and expansion joints where a fire rating is required. It is also suitable for use in penetration sealing systems where pipes and cables pass throug fire rated structures.
