“…Each specific application requires appropriate end-uses properties, characterized by a combination of specific values of tackiness, resistance to shear and resistance to peel. It has been proven that several latex properties, such as copolymer composition, molar mass distribution, gel content, and cross-linking density strongly affect the values of the adhesive properties [16][17][18][19][20][21][22].…”

“…In polymer-modified mortar, both cement hydration and polymers phase formation by the coalescence of polymer particles proceed well to yield a monolithic matrix phase with a network structure in which the cement hydrate phase and polymer interpenetrate into each other, and aggregates were bound by such a co-matrix phase (Tobing, 2000). The strength of polymermodified mortar was affected by various factors that tend to interact with each other: the natural materials, the control factors for mix proportions, curing method and testing method.…”

Polymer modification was widely used to improve the properties of construction materials. The concept of polymer modification for mortar and concrete was put forward 80 years ago. It was known that the use of polymers for modification can greatly improve the strength, adhesion, resilience, impermeability, chemical resistance and durability properties of mortars and concrete. In southern Vietnam, a tropical weather country, the environment was usually hot with high humidity. The durability of mortar or concrete coating was reduced over time in such a condition. This study examines the strength of polymer-modified mortars in high temperature and high humidity. Moreover, the results included the improvement of strength of acrylic emulsion polymer-modified mortar (PMM) by the addition of blast furnace slag. Fifteen percent cement was replaced with blast furnace slag (BFS) in a mix proportion in order to improve strength of PMM. The specimens were cured in cycles 50±2 o C, RH 90±3%, for 5 hours and 20±2 o C, RH 60±3 %, for 19 hours per day. The strength of PMM was measured at the age of 3, 7, 14, 21 and 28 days, 3 and 6 months and 1 year in a high temperature and high humidity cycles.

“…PSAs are viscoelastic materials that can adhere strongly to a wide variety of substrates upon application of slight pressure and a short contact time. [6][7][8] Governmental regulations and consumers' sensitivity to environmental issues are the driving force for the development of waterborne, i.e., solvent-free, PSAs. Traditionally, PSAs have been produced in semi-continuous reactors, which provide a high flexibility (possibility of producing in the same reactor widely different materials with the desired end-use properties [9,10] ).…”

Summary: The feasibility of obtaining specialty waterborne adhesives in a CSTR was investigated facing the possibility of replacing the traditional semi‐batch reactors, which are commonly used in their production by a more efficient system. The key aspects focused on this work were the safety of the process, the kinetic feasibility, and the quality of the products, having as a reference the adhesive performance of the polymers produced in the semi‐batch reactors. Simulations showed that the production of 280 tons per week could be safely carried out even using mean residence times as short as 10 min. From a kinetic point of view, it was found that under these conditions, reasonable high conversions could be achieved in the reactor, resulting on a high production per unit volume of reactor. Furthermore, the adhesive properties of the latex were analyzed, and a much higher shear resistance was found for the latexes produced in the continuous reactor, while peel resistance and tack were found to be very similar disregarding the type of reactor used.Safe process conditions in a CSTR.magnified imageSafe process conditions in a CSTR.
