Methyl ethyl ketone peroxide in Nouryon Butanox LPT-IN diisononyl phthalate 1338-23-4

Butanox LPT-IN
Methyl ethyl ketone peroxide in diisononyl phthalate
CAS No.: 1338-23-4
Physical Form: Liquid
Butanox® LPT-IN is a general-purpose MEKP that provides an exceptionally long gel time in standard phthalate resins and is the product of choice for curing vinyl ester resins.
Applications
Butanox® LPT-IN is a methyl ethyl ketone peroxide (MEKP) used to cure unsaturated polyester resins at room temperature and high temperatures in the presence of cobalt accelerators. Compared to most other peroxyketones, Butanox® LPT-IN offers significantly longer gel times, making it particularly suitable for applications requiring extended gel times or production cycles, such as the manufacture of large parts and fiber winding. Butanox® LPT-IN is also of particular interest in regions with higher ambient temperatures. Butanox® LPT-IN is particularly recommended for curing vinyl ester resins. This MEKP formulation produces less “foaming” than standard MEKP. Years of practical experience have demonstrated that Butanox® LPT-IN guarantees low moisture content and is free of polar compounds, making it highly suitable for GRP products, such as marine applications. The low hydrogen peroxide content of Butanox® LPT-IN makes this peroxide ideal for curing gel coats that are prone to microporosity caused by hydrogen peroxide decomposition.
