  • How many high boiling fluids are a plasticizer?
  • Several thousand high boiling fluids are potential plasticizers for coatings applications. The choice of plasticizer is dependent on compatibility with the resin in use, cost, and other desired attributes. Plasticizers may be classified by both chemical structure and performance characteristics, as shown in Table 1 .
  • Why do we use high boiling fluids as plasticizers?
  • Access your content now. PAINT AND COATING FORMULATIONS OFTEN incorporate high boiling fluids as plasticizers where rigid or brittle resins fail to meet toughness and flexibility requirements. The primary function of the plasticizer is to impart flexibility to the resin, thus minimizing film cracking.
  • What are the characteristics of a plasticizer?
  • Typical plasticizers are liquid esters of molecular weight between about 200 to 800, with specific gravities between 0.75 and 1.35 at 20/20°C, viscosities between 50 to 450 cSt, vapor pressure of less than 3.0 mm of mercury at 200°C, and flash points greater than 120°C (248°F).
  • Are plasticizers a solid or a liquid?
  • Plasticizers are liquids of molecular weight greater than that of solvents—to limit volatility—but are not solids, such as alloying polymers, etc. It should be noted that cross-linked resinous coatings significantly reduce plasticizer loss due to diffusibility and volatility.
