New toughening additives significantly improve their impact and peel strength without reducing the epoxy hardness. Furthermore, modifying epoxies enhances moisture resistance. Choosing the right modifier polarity allows the desired morphology to be exactly achieved. This development can further widen the diversity of the use of epoxy adhesives.

Résistance thermiqueIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Due to their different physical properties, epoxy adhesives and polyurethane adhesives are sold into different segments of the adhesives market. Epoxy adhesives are targeted for applications requiring rigidity, solvent resistance and ultra-high-temperature resistance. Polyurethane adhesives are targeted for applications requiring toughness, processing flexibility, tunable cure rates, low-temperature cure and adhesion to many different substrates.
While the hybridization of epoxy and polyurethane technology is not a new concept for coating applications, the hybridization of adhesives is not as common. Commercial epoxy adhesives face several challenges that can be remedied by hybridizing these two technologies. The most important improvement to epoxies is a reduction in brittleness, which comes from the inherently high crosslink density of epoxy chemistry.Note de contenu : - Epoxy strengthening methods

PrépolymèresUn pré-polymère ou prépolymère est un oligomère ou un polymère présentant des groupes réactifs qui lui permettent de participer à une polymérisation ultérieure et d’incorporer ainsi plusieurs unités monomères dans au moins une chaîne de la macromolécule finale.
Les pré-polymères peuvent être di-fonctionnels (c'est le cas des pré-polymères téléchéliques) ou plurifonctionnels. Dans ce dernier cas, ils sont utilisés pour la fabrication de polymères thermodurcissables par réticulation.

RéticulantsIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Epoxy resins are used in quite a few applications because of their many excellent properties, such as good adherence to a variety of substrates. Unfortunately, epoxy resins are very brittle. Therefore most structural epoxy applications, such as adhesives, are formulated with tougheners. Note de contenu :

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Thermoplastic polyurethanes (TPUs) have been used in the adhesive industry for more than thirty years - most often in solvent-based applications - to impart characteristics such as strength, toughness, chemical resistance and low temperature flexibility. With increasing regulatory requirements and an overall trend toward 'green' materials and processes, alternatives to solvent technologies are actively being sought. Thermoplastic polyurethanes provide advantages in some of these newer systems as well, including hot melts and reactive systems, and in applications from fabric laminating to furniture assembly and bookbinding.
This article addresses the use of thermoplastic polyurethanes in the adhesive industry. A brief overview of the historical use of polyurethane in adhesives is given, followed by a discussion of TPU's utility in more novel technologies and applications. The attributes of TPU as an adhesive raw material are presented, as well as physical property characteristics of certain TPU materials available for use in newer, nonsolvent-based adhesive technologies. Specific formulations particularly well suited for use as components in hot melt adhesives are also presented and discussed.Note de contenu : - Characteristics

Matériaux pour les industries agro-alimentairesIndex. décimale : 667.9 Revêtements et enduits Résumé : Environmental Sustainability is an issue of increasing concern for our planet. So stimulating growth through more sustainable products, resource efficiency and commitment to the environment has reached a critical mass of interest due to the demand of customers, environmental groups, investment firms, government agencies and consumers. Think economically; print ecologically - these two requirements are equally important to combine environmentally friendly production with business success.
Conventional printing inks, adhesives and polymer-based packaging materials have several harmful effects on ecologica I aspects, as well as human wellbeing, thus, eco-friendly alternatives to reduce/ solve the problem are desirable. Over the past few decades the production and application of synthetic polymers and printing ink-related materials have seen an almost exponentia I increase. However, concern regarding depletion of fossil resources, disposai and related issues, as well as government policies has led to thinking about the development of sustainability. Over the last few years, many printing ink manufacturers have moved towards more sustainable inks using phrases like "green", "environmentally friendly", "eco" inks etc. The terms "green" and "sustainable" are often used interchangeably, but they don't mean the same thing. Therefore, choosing suitable materials is very important in food packaging ink and adhesives. The key objective of this article is to elucidate the significance of eco-friendly inks and adhesives and their controlling parameters, which help to curb the equilibrium among human beings and nature by reducing hazardous chemicals.Note de contenu : - HIERARCHY OF CHEMICAL MANAGEMENT : Basic requirements/needs as organisations for sustainable transition - Requirement for transition of green/sustainable inks and adhesives as products - Finish products - Raw materials - Manufacturing process
