application
DJ-A3-MF889F-25 is suitable for the bonding and sealing of all kinds of fire doors, doors and windows, and the flame-retardant sealing of each layer of curtain wall engineering, especially for the gap between the glass curtain wall and its surrounding fire partition components, and the outer edge of the floor or partition wall. Fire-proof sealing of gaps, gaps between the edges of openings on solid walls, etc., and fire-resistant sealing of public places such as waterproof, moisture-proof, decoration
product manual
DJ-A3-MF889F-25 is a single component, high elasticity, low modulus
(LM) flame-retardant materials are used in various forms of buildings, especially high-rise buildings and complex structures for fireproof sealing and sealing. It can be easily extruded and used under most ambient temperatures, and can be cured by reacting with moisture in the air to form a durable weather-resistant silicone sealant. DJ-A3-MF889F-25 can not only meet the requirements of 100/50L .M, but also has good flame retardant and sealing performance; within its displacement capacity, it has strong ability to withstand repeated high and low temperature alternating deformations, which can meet the requirements of construction Industry standard JG/T 475 or European standard ETAG 002 standard silicone fire-retardant structural sealant is used in conjunction with a 25-year quality guarantee.
