Torlon® AI-50 is a wet polymer granule developed for the performance coatings industry. This polyamide-imide precursor consists of roughly 35% polymer solids, 63% water and 2% NMP. The high acid number of the polymer backbone allows the formulation of aqueous solutions with the addition of an appropriate complexing amine. Aqueous-based solutions made with Torlon® AI-50 have inherently low VOCs, which helps end users meet stringent environmental regulations. Coatings based on the Torlon® AI-50 polymer yield durable, thermally-stable films. The cured resin has superior resistance to organic solvents and a wide array of other commercial and industrial chemicals. Outstanding tribological characteristics are afforded both by the resin as well as its unparalleled intra-coat adhesion to fluoropolymers. Aqueous-based AI-50 polymer coatings offer a sustainable solution for electrical/electronic, high temperature decorative and corrosion preventative applications. In addition, magnet wire insulation and protective coatings for printed circuit boards may be converted from solvent-borne (NMP) polyamide-imide solutions. Industrial applications include primers, adhesives, and wear-resistant protective coatings. Aqueous AI-50 polymer solutions may be easily combined with aqueous fluoropolymer dispersions to produce sustainable, high-performance, low-friction, corrosion-resistant coatings that provide protection to industrial and automotive parts.
