HYPER SEAL FSU-300 PU water swelling additive for rubber water-stop
HYPER SEAL FSU-390 Liquid hydrophilic PU water-stop for sheet file interlocks
"HYPER SEAL" is a water-stop sealing product mainly made of specific rubbers, showing double working water-stop effects with more excellent water-stop performance and ease of application than conventional stop plates.
The elasticity of rubber can bring the watertight sealing action between construction joints and show a perfect water-stop performance by completely sealing gaps and waterways around joint, maintaining watertight up to 2-10 times on contact with water flowing into joints.
It is real condition you cannot expect a perfect water-stop effect with one kind of product at construction sites, including civil engineering or construction and special structure on the whole.
At this point, we produce a variety of products to be applied by each condition of construction sites and the part of application.
Perfect Water-stop sealing : Shows the double working water-stop performance.
Work safety : Thanks to elasticity and restoring force, actively deals with deformation of the structure.
Ease of application to :Being lightweight and having good adhesion to any structure makers for easy to work even it narrow spaces.
A Wide range of application : possible to apply in any weather or at any sites.
Semipermanent life : Retains its original from even after repeated expansion.
A water expanded sealing material "Hyper Seal" absorbs and expands it self so as to adhere closely to the contact surface of a structure, showing the water-stop performance.
