SK Functional Polymer (SKFP) has developed a process to prepare LOTADER® terpolymers dispersions. Our studies have shown that the high content of maleic anhydride (MAH) was necessary to obtain stable dispersions. The following LOTADER® terpolymers were evaluated.
The most promising results were obtained with LOTADER® 8200, a resin with melt index of 200. These dispersions showed good adhesion onto substrates such as LDPE, PP and PET. Onto these plastic substrates, the adhesion force is superior to ethylene acid (EAA) and ethylene-methacrylic acid copolymers (EMAA). The two graphs below show the adhesion measured using LOTADER® 8200 dispersions onto PP and PET. Due to the presence of MAH, the dispersions have also high adhesion onto aluminum foil.
LOTADER® dispersions complement PRIMACORTM dispersions which are already used as protective coatings for paper and paperboard.
