LITEX N 3415 M

LITEX N 3415 M is an aqueous, colloidal dispersion of a carboxylated butadiene-acrylonitrile copolymer. LITEX N 3415 M contains an anionic/non-ionic emulsifier system and is stabilized with an antioxidant.



Technical Informations

Application Advice/Typical Applications


LITEX N 3415 M is mainly used as a binder for non-woven fabrics and fibres of all sorts. Non-woven fabrics produced with LITEX N 3415 M are springy and elastic, but somewhat harder than those produced with LITEX T. They are easy to split and buff (as in the manufacture of base materials for synthetic leather). They also have excellent abrasion resistance, as well as being distinguished by good resistance to greases, oils, petrol and plasticizers. LITEX N 3415 M is highly suitable for heat sensitization. After a heat-sensitized impregnating compound has been applied to a substrate, a heat shock (given by infrared lamps or a hot cylinder, for example), precipitates the polymer immediately. This prevents migration of the binder during drying and ensures that the polymer is distributed uniformly over the cross section of the non-woven fabric. Above all LITEX N 3415 M is a suitable binder for thick non-wovens that will be split into thinner sheets (as in the manufacture of base materials for synthetic leather). The impregnating compound must contain the chemicals needed for the vulcanization, since non-wovens with the best possible properties can only be produced if the coagulation and drying are followed by vulcanization. The viscosity of LITEX N 3415 M can be increased by adding conventional thickeners, for example methyl cellulose, carboxymethyl cellulose or acrylic thickeners. On request we will be pleased to provide you with typical formulations for your guidance.
