FS-H High Density Silicone Elastomer(Two-Component)
FS-H (High Density Silicone Elastomer) is commonly used as a bio-shielding refractory caulking material. FS-H consists of two components, A and B. The cured product (A+B) is durable, damage-resistant and easy to clean on the surface. And the radiation shielding effect is equivalent to that of concrete of the same thickness. It is mainly suitable for biological shielding and plugging of ordinary concrete holes and heavyweight concrete.
Simple working condition
Product advantages:
Biological shielding;
Non-toxic smoke;
Over 60 years lifetime;
Water-tight, Smoke-tight;
Radiation resistance;
Resistant to Design Basis Accident( DBA );
Decontaminability (Smooth surfaces can easily be decontaminated.)
No halogen, sulfur or other toxic substances;
Excluding basic and essential chemical elements: copper, lead, zinc, cadmium, tin, antimony, mercury, bismuth and other low-melting-point metals, and their alloys or compounds;
Seismic resistance.
Installation instructions:
Clean the opening;
Stir components A and B separately for about 8 minutes;
Add components A and B to the container and mix them thoroughly at room temperature in a weight ratio of 1:1 for 2 minutes.
Pour the well-mixed liquid into the openings and wait for curing.
