They are characterized by solvent and chemical resistance, great electrical properties, low-temperature flexibility, oxygen and ozone resistance, high impermeability to many gases and moisture, good adhesion properties, and flex-crack resistance.
These low- to high-viscosity polymers have highly reactive terminal thiol or epoxy groups and are widely used as sealants for insulating glass windows, sealants in construction, sealants for aircraft fuel tanks and fuselages, epoxy modifiers, or intumescent protective coatings.
Liquid polysulfide polymers were re-discovered in 1926 by Joseph C. Patrick and Nathan Mnookin when they were trying to react a,v-alkyl halides with inorganic polysulfides (e.g., Na2Sx, x = 4-6). The inventors created high-molecular-weight rubbers with outstanding chemical resistance against solvents, gasoline, ultraviolet (UV) light and ozone.Note de contenu : - Synthesis and chemical structure

Température -- ContrôleIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Prior to the 1980s, it was common for cars to rust. The lower doors and rocker panels were usually the first to go, followed by the floor pans, wheel wells and bumpers. Even the hood, deck lid and the roof were not immune. Aftermarket companies sprang up to “undercoat” cars to prevent rust. Automakers followed suit and offered undercoating as an option as they sought a solution.
Next came modern sealer technologies, which offered the opportunity to prevent corrosion in the places where it was most prevalent. This was far better than aftermarket solutions, which involved drilling holes and installing plugs after spraying. Sealers were incorporated into both the design and the manufacturing process. First applied manually, the sealers were an improvement, but still were unreliable.
In the ’80s, robotics were just coming into their own, and they offered the opportunity to automate the repetitive, tedious, high-precision tasks of which humans quickly grow tired—including the application of sealer. But there was one major problem: hand-eye coordination. A human could watch the bead as it was being applied and change their speed, angle, distance to the part, etc., to create a good bead―something a robot wasn’t capable of doing. For a while, it seemed like robots weren’t cut out for this type of application. Then, in 1990, Saint Clair Systems (SCS) introduced new methods and devices for controlling the temperature of the sealer as it was dispensed, making the application viable. Today, robotically applied sealer is the norm throughout the industry, and virtually every successful system incorporates some form of temperature control to stabilize sealer viscosity.Note de contenu : - Fig. 1.

Produits chimiquesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Access to comprehensive materials data can help adhesive and sealant manufacturers optimize product design and development choices.
To excel, all manufacturing organizations (including those that produce or use adhesives, sealants, and coatings) need an intimate understanding of their products. Products are made out of materials. Materials are shaped, joined, and finished using multiple processes. These are obvious statements, and they point in an equally obvious way to the conclusion that organizations must treat knowledge of their materials and processes as a critical corporate asset.En ligne : http://www.adhesivesmag.com/articles/92869-case-study-material-and-product-intel [...] Format de la ressource électronique : Web Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=23358

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : By itself, concrete has enormous compressive strength but little tensile capacity. Thus, an unreinforced concrete column can support a large load, but a beam has minimal strength without reinforcing steel. Reinforcing steel, also known as rebar, first came into common use near the end of the nineteenth century. Since then, reinforced concrete has become a preferred building material for water storage and conveyance structures, providing great strength and many possible configurations. These advantages, however, come with the challenge of protecting rebar, which is essential for long-term durability. Note de contenu : - REINFORCED CONCRETE DETERIORATION PROCESS
