“…The first property represents the adhesive's ability to adhere quickly (initial grab), and latter one evaluates its ability for not being peeled off, and the last one characterizes the resistance against not being flown when encountering with high shear forces. All in all, the first two characteristics are in direct relation with each other, but inversely related to the last one [15].…”

“…Peel and peel strength are measured by separating an adhesive applied to a substrate at some angle with respect to the substrate, usually at an angle of 90° or 180°. Similar to tack, the measurement of the peel adhesion involves a bonding step before the debonding or peeling step (Figure 9) [7,15].…”

“…First, PSAs are mainly nonstructural adhesives; they cannot be compared with epoxies for structural applications. Moreover, PSAs mainly adhere to a surface upon contact without any chemical reaction [6,15,23,26].…”

“…There are also acrylic polymers in petroleum-based solvents-usually of low to moderate solids content. End users prefer the performance of solvent based acrylic polymers although they are more expensive than their water borne counterparts (latexes) [7,15]. Hot melt PSAs are based on block copolymers.…”

Self-adhesive materials are called, in the adhesive industry, pressure-sensitive adhesives (PSAs). PSAs are designed in the shapes of latex, solvent borne resin, rubber solution, or hot melt and are being used for foils and films, tapes, labels, and notepads which can make permanent, removable, or semi-removable adhesive joints for applications of general purpose product assembly by simple contact under light pressure. This special class of adhesives does not undergo any physical transformation or chemical reaction during the bonding process. The end-use properties of PSAs result from the nonlinear viscoelastic behavior of the adhesive material, and the elastomeric polymer basis of PSAs imparts them such a viscoelastic behavior caused by a carefully chosen polymer architecture and monomer composition with the proper addition of small molecules called tackifying resins. They are safe to use and easy to handle and thus are increasingly replacing more conventional types of adhesives. In this chapter, we review adhesion mechanism of PSAs, types of PSAs, adhesion properties and tests, mechanical behavior of joints, and especially different aspects of PSA applications.

“…Emulsion polymers of vinyl acetate have widespread industrial application (i.e., exterior and interior architectural waterborne coatings, adhesives, and paints) which is due to their low risk of fire, toxicity and cost [1][2][3][4][5]. Vinyl acetate copolymerizes with butyl acrylate and produces useful latex for application in acrylic emulsion paints [6][7][8][9].…”

In a conventional semi‐batch seeded emulsion copolymerization of vinyl acetate/butyl acrylate (VA/BA) using hybrid surfactants namely, dioctyl sulfosuccinate (DOSS) as an anionic surfactant, nonylphenol ethoxylate (KENON 30) as a non‐ionic type, and polydimethylsiloxane surfactant (having hydrophilic silanol‐terminated, called PDMS). The effect of PDMS on the properties of the latex synthesized was investigated by measuring solid content, viscosity, colloidal stability, particle size distributions of the base latex, viscosity average molecular weight (M¯v) of the copolymer, latex particle morphology, glass transition temperature (Tg) of a copolymer and thermal gravimetric analysis (TGA). Particle size of the base latex decreases (Z‐average from 246.48 to 143.69 nm) upon increasing the amount of PDMS surfactant in the recipe (up to 6 wt%). The presence of PDMS surfactant in the hybrid surfactants led to a significant increase in the solid content (from 48.71 to 51.31 wt%), viscosity (from 334 to 806 centipoise, cp) and M¯v (from 1.91 × 105 to 2.34 × 105 g mol−1). Thermal stability and Tg of the copolymer were increased with addition of PDMS surfactant (thermal stability from 344.77 to 389.81 °C and Tg from −20.7 to 21.7 °C). The colloidal stability evaluated using the electrolyte addition method was improved with addition of PDMS surfactant. The uniform morphological structure of the final particle is the main effect of using PDMS in the hybrid surfactants.
