Description
YS-212 modified silicone MS sealant is a one-component non-sagging sealing material, which is composed of the internationally leading modified silicone prepolymer. During construction, YS-212 is applied to the joints with a glue gun to form a paintable and well-displaceable sealing layer.
Use
YS-212 is suitable for sealing and waterproofing of displacement joints between concrete precast panels in PC buildings, as well as joints between PC panels and window frames, shield subway segments, prefabricated integrated pipe gallery pipe section perimeters, thermal insulation and decorative integrated panels, ALC/GRC panels, etc.
Advantages
1. Excellent weather resistance and durability, good stability, long-lasting sealing.
2. No solvent, zero formaldehyde, no silicone oil, no diffusion and no pollution.
3. Stress relief, reliable bonding, deformation with the seam, suitable for the material.
4. Good extrusion, single component, easy to construct, easy to modify and paint.
