  • What is ASTM International?
  • ASTM International is a globally recognized leader in developing and publishing technical standards for materials, products, systems, and services. Explore our expansive library of standards and collaborate with industry experts to advance innovation and assure safety across a wide range of industries.
  • What are ASTM plastics standards?
  • ASTM's plastics standards are instrumental in specifying, testing, and assessing the physical, mechanical, and chemical properties of a wide variety of materials and products that are made of plastic and its polymeric derivatives.
  • 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 .
  • What is a plasticizer used for?
  • Plasticizers are primarily employed in heavy gage coatings and/or when improved toughness is required for industrial, automotive, and appliance applications. Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature.
  • 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).
