发明名称 Polyurea compound
摘要 A polyurea compound obtainable by reacting one or more polyisocyanates with one or more non-chiral mono-amines (I) and one or more chiral mono-amines (II) and co-precipitating the reaction products to form the polyurea compound, wherein 2-98 mole % of the mono-amines in the polyurea compound are chiral mono-amines. The invention also relates to the use of said polyurea compound as a rheology modification agent, in particular as sag control agent (SCA) in coating compositions. The invention further relates to sag control agent compositions, coating compositions and coatings comprising the polyurea compound as sag control agent.
