Product Application

PnB is mainly used as cleaning agent for heavy contaminant. It can dissolve coupling oil and grease efficiently and make itself suitable for the formula of household and industrial. Partially soluble in water, PnB can solubilize most solvent with the application as follows:

① as household and industrial cleanser, remover of grease and paint, coupling agent and solvent of metal and hard surface cleanser;

② as effective coupling agent and solvent of water-reducing coatings;

③ as effective coagulating agent of water-based emulsion paint;

④ as active solvent of solvent-based paint;

⑤ as chemical intermediate for ester, solvent and plasticizer manufacture.

DPnB
Application in coating: as one of the best film-forming auxiliaries of water-based paints, DPnB can be used as coagulant of acrylic resin, phenylethylene acrylic resin and polyvinyl acetate giving excellent performance to paint film.
Application in cleanser: it is applicable to cleaning agents especially for those which require low volatile speed, such as wax remover and floor cleanser. As good coupling agent for lubricating grease and fat, DPnB can be applied as paint stripper and remover of animal fat.
Other application: DPnB can also be used in agricultural products, cosmetics, electronic ink and textile.
