General sealantsfor construction

Silicone sealants are elastic sealing materials that offer outstanding durability, weather resistance, and adhesion. As buildings and structures move, such as during earthquakes and typhoons, silicone sealants move flexibly with them. They are therefore commonly used in sealing applications in high-rise buildings and housing, civil engineering, clean rooms, and in the joints of aquariums.

Functional sealants for structural glazing


Durability and weather resistance

Outstanding durability and weather resistance, with almost no degradation from UV rays or ozone.


With the use of an appropriate primer, silicone sealants offer high adhesion to almost all materials.

Moisture resistance

Our silicone sealants have superior durability, weatherability, and adhesiveness, so they form airtight, moisture-proof seals that last for years.

Resistance to salt damage

Silicone sealants are highly resistant to salt damage, so they can be used in buildings and factories in coastal areas, offering high durability.
