An Overview of the Use of Rheology for Adhesive Manufacturers
نویسندگان
چکیده
Several aspects of the rheology of adhesives are important for their application and end use. Coating an adhesive requires the viscosity to fall between maximum and minimum viscosity limits and these depend upon the type of coating process that is to be used. Viscosity data is shown for the maximum and minimum acceptable limits for several types of coater. The modification of the flow properties by changing the solids loading and particle size distribution is discussed. After application and drying, an adhesive’s viscoelastic properties can be used to assess its performance. Oscillation frequency sweep data can show whether the adhesive will have good tack properties, whether it will form an immobilized joint and if it will peel off easily (if needed) after use. Data is shown for good and bad diaper adhesives

متن کاملComparison of the Bond Strength of Fiber-Reinforced Composite (FRC) Posts to Radicular Dentin Using Different Adhesive Cement: an in-vitro study
Introduction: Retention of fiber reinforced composite posts depends on the bond strength between post and cement, and cement and root dentin. The aim of this study is to evaluate the bond strength of one type of fiber post to radicular dentin with different adhesive cements. Materials and Methods: Crowns of 44 caries-free, human premolar were removed 2 mm below the CEJ and the roots were endod...
متن کاملAnalytical Solution of Stress Field in Adhesively Bonded Composite Single-Lap Joints Under Mechanical Loadings
In this paper, considering an adhesively bonded composite single-lap joint, a novel approach is presented to predict the peel and shear stress distributions of the adhesive layer for an ASTM standard test sample. In current method, the equilibrium equations are derived using the energy method and based on the Timoshenko’s beam theory. Two solution procedures then are discussed, one of which rep...
