Detailed Description

YAC-N813 can be used as a surface modifier to generate hydrophobicity, e.g. on concrete, glass, inorganic pigments, or mineral fillers. The medium-chain alkyl functionality results in unique compound properties when YAC-N813 treated minerals or pigments are incorporated into polymers, e.g. Polyethylene or Polypropylene. Loading levels of 0.5% to 1.5% YAC-N813 based on the weight of fillers or pigments are typically recommended.

YAC-N813 can also be used to improve the compatibility of mineral fillers or pigments in Polyolefins or to ease their dispersion in non-polar materials.

YAC-N813 is a small molecule to allow for deep penetration into the cementitious surface. This material reacts with moisture in the air and in the substrate in the presence of an alkaline or acidic environment to produce hydroxy groups. These hydroxy groups will bond with the substrate and itself to produce a hydrophobic treatment that inhibits water absorption into the substrate. An alkaline environment, such as new concrete, will catalyze the reaction and speed the formation of the hydrophobic surface. Typical dilution levels: 20~40% with solvent.
