A standard or control specimen of a material is always recommended for comparison to the specimen under study 1.3 FORMULATION AND DEFORMULATION A paint, plastic, adhesive, or ink is actually a mixture of materials to create a formulation Almost all formulations are types of dispersions including emulsions and suspensions, and separation of the phases is the first step of. .. consists of a logical scheme to allow the reader to identify a particular area of interest The basic scheme consists of formulations, materials used in the formulation, and followed by methods of deformulation The reader is referred to texts on qualitative and quantitative chemistry principles and techniques for precise laboratory methods There is a deformulation chapter following each paint, plastics, adhesives,. .. chapter following each paint, plastics, adhesives, and inks materials chapter Many of the deformulation principles are similar For this reason, the information is usually discussed once and referred to in other deformulation chapters to eliminate repetition of the material 1 2 Chapter 1 Standard materials found in formulations are well characterized, and the results are presented in each case The reader... 12.5 Scheme for deformulation of liquid adhesive specimen CHAPTER 15 Figure 15.1 Figure 15.2 Figure 15.3 Figure 15.4 Figure 15.5 Scheme for preparation of solid ink specimen for deformulation Scheme for deformulation of a solid ink specimen SEM micrographs of washable black writing pen ink Scheme for preparation of liquid ink specimen Scheme for deformulation of liquid ink specimen 1 Deformulation Principles... Chapters 2 (surface analysis) and 3 (bulk analysis) together with corresponding analytical instruments No investigation can be performed without the proper tools, and materials such as polymers and pigments require corresponding instrumentation for identification and characterization such as infrared spectroscopy and X-ray diffraction The methods and equipment for surface and bulk analysis are discussed... isolation of a mixture of chemical compounds before an identification of individual components can be attempted The state and chemical nature of materials vary widely, and require a host of analytical tools Historically, the strategy for analysis has varied as widely Strategy is provided for using proven methods to untangle and characterize multicomponents from a single formulation The structure of this . alt="" Analysis and Deformulation of Polymeric Materials Paints, Plastics, Adhesives, and Inks TOPICS IN APPLIED CHEMISTRY Series Editors: Alan R.
