What makes Demsun D20 the best Sanitary Silicone for bathrooms?
Demsun D20 Super Sanitary Silicone is engineered to solve the most common problem in wet rooms: black mould spots. As a high-grade sanitary silicone, it utilizes a powerful antimicrobial formula that protects the sealant bead from discoloration and degradation caused by bacteria and fungi. This makes it the professional choice for sealing high-moisture zones such as shower cubicles, bathtubs, and kitchen splashbacks.
Superior Adhesion and Durability
This sanitary silicone offers excellent primerless adhesion to a wide variety of non-porous surfaces. It bonds instantly to ceramic tiles, porcelain, glass, aluminum, and vitreous enamel. Unlike standard fillers, the D20 remains permanently elastic once cured. This flexibility allows the sealant to accommodate the slight structural shifts or “settling” that occurs when a bathtub is filled with water, preventing the seal from pulling away or cracking.
UV Stability and Colour Retention
Many white sealants turn yellow over time due to UV exposure or chemical cleaning. Demsun D20 is formulated to be non-yellowing and UV-resistant, maintaining its “Brilliant White” finish even in bathrooms with large windows. It is also resistant to common household detergents and hot water, ensuring that the seal remains intact and aesthetically pleasing throughout its lifespan.
