Solvants -- Suppression ou remplacementIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Rubber covered rolls, or rollers, are used to handle a variety of materials in business and industry. Depending on the application, rollers may be exposed to high pressure, heat and potentially damaging fluids such as caustics, acids and solvents. The durability of the bond between the roller core and the rubber covering is critical to performance of the roller.
Manufacturers of rubber covered rolls have a long history of succesful use of solvent-borne rubber to metal (R/M) adhesives. Passage of the U. S. Clean Air Act Amendments (CAAA) in 1990, however, has had a significant impact on the future use of these adhesives. Title I of the CAAA requires that emissions of volatile organic compounds (VOCs) be reduced. Typical R/M adhesive contain as much as 6.0 to 7.0 lb VOC per gal. Decreasing the amount of solvent is not a viable option because of consequent difficulties in adhesive application. VOC-exempt solvents, such as 1,1,1-trichloroethane, will soon be banned from production due to their ozone depleting potential.
In addition to Title I regulations, many traditional R/M adhesives contain solvents considered hazardous air pollutants (HAPs) under Title III of the Clean Air Act. Emissions of these substances lust be controlled through the use of "maximum achievable control technology". This includes emission control equipment such as incinerators or carbon absorbers, but can also include the use of compliant adhesives that contain no HAPs.
Given the current regulatory climate, development options for R/M adhesive formulators are limited to 100% solids or aqueous systems.Note de contenu : - Aqueous adhesives

PhosphiteL'ion phosphite (HPO32−) est un ion polyatomique avec un atome central de phosphore. Sa géométrie est pyramidale trigonale. De nombreux sels de phosphite, tels le phosphite d'ammonium, sont hautement solubles dans l'eau. Le terme « phosphite » est parfois employé pour désigner l'ester de phosphite, composé organophosphoré de formule P(OR)3Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Based on primary/secondary antioxidants, the system offers improved performance over conventional stabilization systems in ethylene-vinyl acetate/hydrocabon tackifier hot melt adhesive formulations.
Hot melt adhesive (HMA) formulations can include antioxidants to inhibit the negative effects of thermally induced oxidation on the physical properties of the adhesive, such as discoloration and changes in viscosity. In addition, degradation not only affects the quality of the adhesive but can also affect processing. Skin formation, which occurs at the interface between the HMA and the atmosphere, can cause equipment fouling during mixing and application. Viscosity changes in the HMA can lead to flow control and application problems. Resistance to discoloration is critical, especially in premium applications. Ethylene-vinyl acetate (EVA)/hydrocarbon (HC) tackifier-based HMAs often are used in applications where color is important. Depending on the hydrocarbon tackifier selected, an EVA/HCbased HMA formulation can have an initial Gardner color number of 1 or less. Retention of initial color during compounding, application and service life of the HMA is desirable.Note de contenu : - Thermal oxidation and degradation

Fibérisation
Produits d'hygiène jetablesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : Technology for fibrous application of pressure sensitive adhesives -- in particular sprayed applications of hot melt adhesives -- has evolved to more efficiently adapt to the needs of the disposable sanitary product market.
In any dynamic industry, the participants, whether suppliers or manufacturers, are all interested in the future. Being the first with tomorrow's technologies and products is the key to succeeding in a rapidly changing marketplace. Before discussing sprayed applications of hot melt adhesive, especially in disposable diapers and other sanitary products, two points should be made. First, several adhesive equipment manufacturers sell heads that fiberize hot melt adhesives. Second, some of the following specific application information was gathered from published data, including patents, and commercially available products that were taken apart to determine how they were put together. By discussing specific products and applications no claims are made regarding which brand of equipment should be used for these applications.Note de contenu : - DISPOSABLE PRODUCT REVIEW
