Polinox’s Brasnox DM50 Offers Advantages in Gelcoat

Polinox’s Brasnox DM50 Offers Advantages in Gelcoat

One of the most challenging applications for methyl ethyl ketone peroxides (MEKP) occurs in gelcoats, reports Brazilian company Polinox. Hybrids of resins and pigments that protect and finish composite parts, gelcoats undergo important changes in their performance if the peroxide exhibits, for example, a high concentration of water. The company says defects such as roughness and early yellowing of the laminate can be avoided with the adoption of peroxides such as its Brasnox DM50.

The company’s flagship product – in 2017, it accounted for 60% of sales – Brasnox DM50 has a water concentration of less than 2.5%, as well as low levels of free hydrogen peroxide (less than 2%). It is also free of glycol.

“These characteristics made the product a reference,” says Sérgio Andrade, Polinox’s Industrial Manager. “This is why Brasnox DM50 is part of the lamination plans of the leaders of various market segments, such as transportation, civil construction, wind energy and nautical.”

Besides its use in gelcoats, Brasnox DM50 is employed for the polymerisation of polyester and vinyl ester resins.
