HT3260A/HT3260B is a two-component aromatic solvent based polyurethane adhesive which is specially designed for pesticide packaging. The laminated structure can obtain higher initial bonding strength and final bonding strength, it is also available for 121℃ retorting film/foil food packaging. The adhesive has certain resistance to media and corrosion, and is excellent in coating. It is widely used in laminations of BOPP、PET、NY、PE、RCPP、AL, etc.
