TIGHTSILANE™series -Permeable materials that prevent water absorption in concrete

TIGHTSILANE™ series is Japan’s first water-based material that prevents deterioration due to water absorption in concrete.
Most of the deterioration of concrete structures is caused by water intrusion into concrete, and TIGHTSILANE™ prevents this and improves the durability of concrete.

Characteristics 

Maintaining beauty

There is no change in appearance after application, and the texture of the material is maintained for a long time.

High permeability/durability

Penetrates deeply from the body surface through capillary action, forming a strong hydrophobic layer.
Therefore, the durability of the water absorption prevention effect is dramatically improved.

Penetration depth and water repellency

After applying each material to the top of the specimen, cut it and dye the cut surface with water-based ink. The unstained area indicates the depth of the hydrophobic layer.

safety

Being water-based based, it is extremely safe, easy to store and work with, and provides an excellent working environment.
