MF1602 prefabricated building silicone modified polyurethane sealant is a single-component, room temperature curing neutral sealant. This product does not contain toxic and harmful substances, has low modulus, good flexibility, no pollution to the environment, and has good bonding ability to most building materials such as concrete, stone, aluminum, etc. It can be widely used in various building exterior wall caulking and sealing, indoor caulking and sealing, door and window installation, building material bonding and other fields in residential industrialization. It has the characteristics of low modulus, good flexibility, environmental protection and no pollution, and has excellent weather aging resistance.

Features and Benefits
◇Environmental protection: low VOC, non-toxic, odorless, no pollution to the base material, no corrosion;
◎The surface can be painted: after the surface is dry, the surface can be sprayed with paint for coloring;
◇Good operability: Sheep component, easy to operate, just use a glue gun for direct
construction:
◇Excellent adhesion: Excellent adhesion to most building materials such as
concrete, stone, and aluminum;
●The displacement capacity reaches 25LM, which can well adapt to cement concrete joints. It has
low displacement modulus, good flexibility, and excellent weather aging resistance.

Application method
Before using this product, operators must read the product safety information carefully.
● The construction surface must be clean, dry, free of dust, water stains, frost,
Dirt, residual sealant, etc.
● Paste protective tape on both sides of the construction surface, and use appropriate backing materials within the joints.
fee.
Cut the tip according to the required size, and squeeze it into and fill the interface continuously.
The amount of glue applied should be enough to fully contact the bonding sealing surface.
When the surface of the sealant has not yet formed a skin, use appropriate force to flatten the sealant.
