In response to regulatory changes in Europe regarding the use of products containing isocyanate, Fosroc ANZ is spearheading the push in Australia and New Zealand for safer isocyanate-free sealants.
Nitoseal MS250, one of Fosroc ANZ's Nitoseal MS hybrid range, is a UV resistant, non-trafficable, elastomeric joint sealant for use on facades and general construction joints.
Like its sister product, Nitoseal MS400, Nitoseal MS250 uses state-of-the-art Duraflex technology which provides the weathering and adhesion performance of silicone sealants, with the strength and toughness of polyurethanes - without the isocyanates.
Superior performance and easier application
Not only does Nitoseal MS250 offer superior performance in terms of durability, applicators also find it produces less stringing and is easier to gun out.
According to Fosroc ANZ’s sealant specialist, Technical Support Manager, Martin Venn, Nitoseal MS hyrid products are the perfect alternative for applicators and specifiers who wish to avoid isocyanates.
"The Nitoseal MS hybrid range offers enhanced safety, without compromising on performance," he explains.
"Given their advantages in terms of performance, usability and safety, I can see the Nitoseal MS products becoming the new sealant of choice," he says.
Where is Nitoseal MS250 used?
Typical applications for Nitoseal MS250 include:
- Sealing moving or static joints in building facades
- General construction where high UV resistance is required
- Precast and insitu concrete, curtain walls, lightweight cladding, tilt-up slabs, brick and blockwork.
The risk of isocyanates
Most sealants on the market contain isocyanates. Isocyanates are a group of highly reactive organic compounds commonly found in materials such as polyurethane foams, synthetic rubbers, paints and varnishes. These compounds easily become volatile and enter the atmosphere as a vapour.
Exposure to isocyanates can result in irritation of the nose, throat and eyes. It can cause coughing, wheezing and shortness of breath, as well as nausea, vomiting, and headaches. Direct contact with the skin or eyes can result in conjunctivitis, blistering, and irritation. Prolonged exposure can cause liver and kidney disease, chronic lung damage or cancer.
