3 Polymerization of hydrophobic alberdingk AC2403. A type of Hydrophobic Emulsion Polymer Select: Hydrophobic monomers Reduce emulsifier content, use as less as possible Reduce polymerization initiator content super water resistance super intercoat layer adhesion Very high barrier properties (almost no water absorption and water vapour transmission). alberdingk Resins (Shenzhen) Co., Ltd. | AC 2403 - A super hydrophobic acrylic resin Chart 4. Benefits of two phase acrylic dispersions Low MFFT combined with high surface hardness Less VOC demand in formulations Fast drying and high blocking resistance High level of elasticity Fast sandability alberdingk Resins (Shenzhen) Co.

7 alberdingk Resins (Shenzhen) Co., Ltd. | AC 2403 - A super hydrophobic acrylic resin Chart 10. 1. alberdingk AC 2403 anti-corrosive applicaiton / formulation guidelines Choice of pigments / extenders / functional anti-corrosive use talc or mica based (lamellar fillers) for best water barrier Bariumsulfate ( Blanc fixe micro) will not compromise gloss levels. no additional benefit by using anticorrosive pigments like zinc phosphates anticorrosive pigments are labelled as hazardous to the environment (N). they may harm the stabilisation system of polymer dispersions (due to Ca2+ , Zn2+, Ba2+ or Sr2+ Ions).

8 Will decrease the gloss of the corresponding coating films. Anticorrosive pigments can be a handicap for cost efficient corrosion protection. alberdingk Resins (Shenzhen) Co., Ltd. | AC 2403 - A super hydrophobic acrylic resin Chart 11. 1. alberdingk AC 2403 anti-corrosive applicaiton / formulation guidelines Dispersants choice choice of dispersant not only affects gloss and corrosion resistance but also adhesion properties and film hardness. Our standard recommendation is Orotan 165 or Edaplan 490. (M nzing Chemie). alberdingk Resins (Shenzhen) Co.
