Abstract
This report describes various applications of Ajinomoto's surface treating agents in thermosets and coatings.
Titanate and alminate coupling agents improve the surface conditions of various inorganic fillers and pigments, and recently two kinds of amino acid-derived materials (AMIHOPE LL and AA-1212) were developed as surface modifiers for inorganic additives.
(1) Inorganic fillers which are treated with a small quantity of a titanate coupling agents, KEN-REACT (in Japan, PLENACT), are well compatible with organic materials, resulting in good filling and homogenous dispersion.
(2) Aluminate coupling agent AL-M has an excellent dispersing effect on pigments.
(3) AMIHOPE LL (N-Lauroyl-L-lysine) is a hexagonal plate form, which shows very smooth touch and good spreadability. LL improves the surface of inorganic materials and makes them compatible with oils.
(4) AA-1212 (N-Lauryl-DL-aspartic acid-β-laurylester) is a columnar heat resisting lubricating powder (m. p. 177°C). AA-1212 improves the surface of inorganic materials and makes them compatible with oils. It is useful as an additive of plastics.
