Product Description – PR146<\/strong><\/h3>\n

HP RED 25107 (PIGMENT RED 146) is bluish red pigment with very good solvent resistance, primarily used in Slovent based printing inks, coatings and paints. It is somewhat yellower than PR57:1, with good perfoamnce in inks. And also very good light fastness in textile printings. is primarily applied in emulsiion and architectural paints as well, and also used in general industrial paints where durability is not important.<\/p>\n

  • Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = \u2018Poor\u2019 and 8 = \u2018Excellent\u2019.<\/li>\n
  • Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.<\/li>\n
  • Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.<\/li>\n
  • Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
    \nwhere 1 = \u2018Heavy bleeding\u2019 and 5 = \u2018No bleeding”<\/li>\n<\/ul>\n
