Abstract
An aqueous polybutadiene dispersion is applied as the adhesive intermediary layer in the preparation of polyamide coatings on metal objects by a process of sintering the polyamide powders. The dispersion contains a liquid polybutadiene with a dynamic viscosity from about 70 to 30,000 millipascal seconds and with a configuration of 40 to 95% of cis-1,4-polybutadiene, 0 to 30% of trans-1,4-polybutadiene, 1 to 60% of 1,2-polybutadiene and, referred to the polybutadiene, 0.5 to 10% by weight of an emulsifier.
