Product Description

DJ-A3-MF881F fireproof sealant
product manual
Meet the requirements of building structure sealant standards
Good adhesion to most substrates, including coated glass, colored glazed glass, anodized aluminum and stainless steel, etc.
No pollution and no corrosion to the substrate to be adhered
It has good stability in the working environment of -60°C ~ 180C. Product advantages
Excellent flame retardancy
Excellent mechanical properties and weathering resistance

Application field
DJ-A3-MF881F fire-resistant sealant is mainly used for structural assembly of building curtain walls, and flame-retardant sealing of various types of fire-resistant doors and windows, curtain wall projects, and public places such as waterproof, moisture-proof and decoration.

product description
DJ-A3-MF881F is a two-component room temperature neutral curing silicone structural sealant with dual functions of fire retardant and structural bonding and assembly. Neutral dealcoholization type, curing at room temperature and releasing a small amount of alcoholic gas.

Related standards
DJ-A3-MF881F can meet the Chinese structural sealant standard GB16776, and the combustion performance meets the GB/T2408 vertical combustion performance and the FV-0 level requirement. Good flame retardancy, excellent mechanical properties and weathering resistance ensure a long service life of the sealant.

Instructions
DJ-A3-MF881F does not require primer to have good adhesion to most coated and non-coated glass, metal spacers, etc. In order to ensure the quality of the project, it is recommended to do compatibility and cohesive tests in advance before each project is used. Mixing ratio In order to obtain better physical properties, it is recommended that the base and curing agent be mixed in a completely closed mixing system. An automatic glue spreader can be used instead of hand or hand-held agitators, because it is easy to mix during the mixing process. Bring in air and affect the physical properties of the sealant after curing. In order to obtain the best sealant performance, the ratio of base rubber and curing agent should be mixed at a mass ratio of 12:1, or an equivalent volume ratio of 8.5:1. Under this mixing ratio, the construction period of the sealant should be 30min~50min, and the surface drying time should be within 2h.The mixing ratio is allowed to be adjusted in a small range, but the quality ratio is preferably 11:1~14:1 range between. It is recommended to stir the curing agent evenly before use. Because the curing agent is easy to interact with Moisture in the air reacts and cannot be exposed to the air for a long time.
Excellent adhesion to a wide range of substrates including coated, enamelled and reflective glasses, anodised and polyester paint coated aluminium and stainless steel. 
Excellent temperature stability: - 60°C t 1ao0c. 
High level of mechanical properties. 
High elasticity and high modulus. 
Resistant to ozone.
