Bright red exterior wall latex paint formula

Introduction

• Bright red exterior wall latex paint can reproduce the national standard color 1086 color exterior wall latex paint production technology, which can reproduce the national standard color 1086 in a short time, and can also ensure the accuracy of the color to the maximum extent.
  Choose the color matching with the required color After the color paste-related latex base paint is evenly mixed by a color mixing machine and a color paint mixer, the color difference between the prepared color latex paint and the standard color card of architectural coatings is within the allowable range, so The weather resistance of the display color is also guaranteed to a certain extent.
  

Application field

• Bright red exterior wall latex paint is used for building exterior wall decoration.
  

Recipe details

Production Method

• After the above raw materials are prepared, add cosolvent, dispersant, and defoamer to the water according to the formula (parts by mass) of the latex base paint, stir evenly at low speed and slowly add pigments and fillers, and then disperse the pigments and fillers at high speed, and then sand until The fineness is less than 30μm, filter.
  After the filtration is completed, under low-speed stirring conditions, add wetting agent, defoamer, film-forming aid, emulsion to the above-mentioned dispersed slurry, and then add thickener to adjust the viscosity to 90~100KU, add pH adjuster to make The pH value is 8.
  5~9.
  0, slow defoaming completes the preparation of latex base paint.
