Description
Soudal Contractors 701 NS Silicone is a high-performing, low modulus, neutral cure sanitary silicone that’s virtually odourless and free of MEKO, built for applications needing a genuine waterproof seal with maximum protection against mould and mildew. Being neutral curing and MEKO-free is a real practical benefit during application — a strong acetic odour and skin sensitisation risk are both avoided, making it more comfortable to work with in confined bathrooms and kitchens.
Once cured, it’s permanently elastic and impervious to mould, and it’s genuinely colourfast and UV resistant, so it holds its colour and flexibility rather than yellowing or stiffening over time. Its low modulus formulation gives very good adhesion on many materials while staying softer under stress than a high modulus sealant, which matters specifically on synthetic baths and tubs and other surfaces where a stiffer sealant risks pulling at the joint edge.
Available across 12 colours — from Brilliant White and Off White through to Charcoal and Translucent — it gives genuine flexibility to match sanitary fittings, tile grout or surrounding trim. It’s rated for joints in sanitary rooms, kitchens, and all usual building joints with high movement, including expansion joints between different construction materials, making it a genuinely versatile choice beyond just bathroom and kitchen sealing.
Its neutral cure chemistry also makes it gentler on surrounding materials during application than an acidic silicone, a genuine consideration on synthetic baths and tubs where an acetic-cure product can sometimes cause surface issues.
