B2B Guide | Material Innovation
You may have seen sealants in the bathroom turn yellow, peel from tiles, or grow hard-to-remove black mold around sinks and bathtubs. However, simply replacing the old sealant cannot completely solve the problem. Choosing the right chemical composition and products with mold-proof formulas is equally crucial. In this guide, we will explore why MS polymer technology has attracted much attention, how to choose anti-mold sealants, and highlight how the new WD166 mold-proof formula redefines the future of sanitary sealants.
1. What is MS Polymer Sealant?
MS polymer technology was initially developed by the Japanese company KANEKA and has been evolving for more than 30 years. Early MS sealants had low modulus elasticity. Through continuous development and formula improvement by researchers, current MS sealants have been greatly improved in both performance and application scope. Unlike traditional silicone and polyurethane sealants, MS polymers combine the advantages of both, achieving a unique balance between adhesion, elasticity, and paintability. It can cover almost all interior decoration scenarios including kitchens, bathrooms, living rooms, and washbasins. You can perfectly use MS sealants on tile joints and paint them with color.
2. Why MS Polymer is the Future of Sanitary Sealants
Unlike many polyurethane sealants, MS polymer sealants are solvent-free, contain no isocyanates, and have low VOC content. When some solvent-containing sealants cure, the solvent evaporates, causing shrinkage. This shrinkage will affect the aesthetics of the joints and may reduce sealing performance, leading to cracking or even a complete loss of adhesion. However, MS polymer sealants are solvent-free and have an extremely low degree of shrinkage. In addition to affecting physical performance, isocyanates and solvents can cause serious health problems, irritating the eyes, nose, throat, digestive system, and skin. They can also cause pneumonia, which is inflammation of the lung tissue.
MS sealants can adhere firmly to damp substrates, which polyurethane or silicone cannot achieve. This strong adhesion on wet surfaces makes MS polymer sealants highly suitable for use under harsh conditions such as rain and snow.
3. WD166 Mould-Proof Guide
Actually, it is not the sealant itself that molds, but inorganic matter attached to the surface of the sealant. Mold uses the inorganic matter here to grow wantonly. The long-term metabolism of these microorganisms will cause the sealant material to be destroyed, resulting in black spots, or a loss of elasticity and adhesion. The structure of MS polymer itself is not a natural fungicide and will not form a lasting anti-mold effect. Especially in high-humidity environments like bathrooms, only by adding active ingredients to the sealant formula can fungal growth be effectively inhibited.
As the most suitable sealant for kitchens and bathrooms, the formula of WD166 MS anti-mold sealant is worth discussing in depth. The competitive advantage of WD166 is not just the MS polymer base; we should see how the mold-proof formula actually works. The WEIDU laboratory has conducted comparative tests on different antimicrobial additives. The experimental results show that inferior fungicides still exhibit mycelial growth and cannot effectively inhibit mold. WD166 adopts a specialized bactericidal formula, and the mold-proof active ingredients are not easy to degrade, achieving a level 0 anti-mold rating. For interior decoration projects, WD166 is an ideal choice. It is highly environmentally friendly and suitable for construction workers and building users who need strictly controlled chemical exposure.
4. Which Scenarios is WD166 Suitable For?
1. Bathrooms and washrooms: Washbasin edges, bathtub joints, around shower rooms, junctions of sanitary ware and tiles, and around urinals.
2. Kitchens and interior decoration: Around kitchen sinks, junctions of countertops and walls, and applicable tile and decorative joints.
3. Around swimming pools and high-humidity public facilities: For example, applicable tile joints around swimming pools and other high-humidity indoor public sanitary facilities. (Not suitable for underwater construction or joints subjected to continuous long-term water immersion.)
However, the anti-mold performance of mold-proof sealants also has a great relationship with construction techniques and daily maintenance. As mentioned by the U.S. Environmental Protection Agency (EPA):
“Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.”

5. How to Choose the Best Mold Sealants
The most suitable mold-proof sealant is not the most expensive one, nor the most adhesive or strongest one, but the product whose performance indicators, adhesion ability, and water resistance limits have been thoroughly tested to match the actual joints. First, do not purchase a product directly just because the packaging has “anti-mold” or “mold-proof” logos. Anti-mold performance requires test data as support, such as checking the anti-mold test reports provided by the manufacturer or the product Technical Data Sheet (TDS).
Most importantly, before making a procurement decision, you can evaluate based on project needs and contact us to request WD166 test reports and samples for verification. We ensure that product performance is strictly consistent with the TDS. Ready to explore the new generation of sanitary sealants?
