PolyacryliquesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Pressure-sensitive adhesives (PSAs) have become more popular in demanding tape and label applications. Many high-performance PSA applications are dominated by solvent acrylic PSAs and radiation-curable PSAs because they can achieve much higher cohesive strength and heat resistance than other technologies, including typical emulsion PSAs. Due to these performance limitations, waterborne emulsion PSAs are used in less demanding applications.
Waterborne acrylic PSAs provide many advantages such as high solids, lower cost, low hazard, and environmental benefits. With these advantages, industry has been pushing the limits of emulsion technologies to close the performance gaps between emulsion and other high-performance technologies.
A new waterborne technology with excellent adhesion and high-temperature properties has been developed that can rival existing solvent acrylic and radiation-curable technologies that are currently used in high-performance applications. The high temperature resistance is measured by shear adhesion failure temperature (SAFT; PSTC-17 test method), which has been the biggest limitation of waterborne PSAs vs. radiation-curable and solvent acrylic PSAs.Note de contenu : - Adhesive properties

Transition vitreuseIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Pressure sensitive adhesives (PSAs) are found everywhere in our society. Solventborne PSA formulations traditionally were based on modified rubber chemistry. Today they are being replaced by low-VOC, fast-curing systems such as UV-cured PSAs.
This article describes current water-based and 100% solid UV-curable PSAs and their properties. Shear, peel strengh and tack properties are reported for systems with various oligomer and monomer contents.
The PSAs were prepared to minimize premature polymerization and evaluated by three test methods: rolling ball tack (RBT), 180° peel and shear. The article describes sample preparation, test methods and significant findings. These findings reveal a correlation between crosslink density and shear performance, tackifier content and peel strength, and system Tg.En ligne : https://drive.google.com/file/d/14rt32Abr9vR1G6ff-SKpg5A3adVAjN9M/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=20386

RhéologieIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Analyzing the development of new novel high performance emulsion pressure sensitive adhesives. We have developed a family of high performance acrylic pressure sensitive adhesives (PSAs) using a novel emulsion polymerization technology. These new PSAs exhibit an excellent balance of peel and shear performances. The base polymers of these PSAs are compatible with many traditional tackifiers and other additives that allow greater formulation versatility for paper and film applications. This paper presents the new base polymers properties, capabilities and highlights our recent work for the removable and repositionable PSA applications. The markets and technology in the PSA industry are growing rapidly. Due to the VOC concern, many of the new applications also utilize emulsion PSAs. To meet the challenging market needs, we utilized new raw materials, processes and new chemistry to develop new emulsion PSAs that have higher performance and better environmental compliance. Although generally, waterborne PSAs have some shortfalls in performance compared to solution PSAs, new technology is closing this gap. The versatility of acrylic chemistry and polymerization processes allowed us to design base polymers with unique properties. Note de contenu : I. New GELVA emulsion polymers

Formulation (Génie chimique)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Millions of tons of waterborne adhesive formulations are sold each year for the industrial production of myriad manufacturer and consumer products. Applications include paper packaging and converting, construction products, automotive assembly, woodworking, paper and non-woven production, and carpet or textile bonding. The formulator’s art is the creative balancing of economics vs. multiple levels of performance requirements. In this Darwinian marketplace, everything is a trade off, and “survivor” products are fueled by an optimum balance of economics and performance (vs. less ideal, perhaps older, formulations).
A major factor to consider in the bonding process is the machining or processability of an adhesive system. The unique characteristics of time, temperature and pressure that are specific to each machine’s process can demand a formulation be designed for each combination of machine and substrate. Research and development efficiency requires that a point of diminishing returns be reached and a formulation be released in order to move on to another high-priority project. Each experiment in this development process may require a lab step to prepare the formulation and pass judgment on the merits of the mixture. Few tools currently exist to help with these experiments, and experience often drives the choices.Note de contenu : - Developing formulations
