Commonly, polymers with low and high molecular weights are blended to obtain the best balance between melt viscosity, wetting and material cohesive strength. The polymers are generally compounded with tackifiers (both rosin and terpene types are used), waxes (to lower melt viscosity and cost) and...

Double dip commercial adhesive systems contain two separate dips. The first dip typically comprises isocyanate, epoxy, wetting agent, and a buffer material to maintain the pH during extended treating periods. In such a system, the isocyanate comprises approximately 65-75 percent of the dry weight a...
The pressure sensitive adhesive dispersion obtained from the process of the invention successfully avoids the “ghost shadow” on the protected surface. For example, in an embodiment of the invention, the pressure sensitive adhesive from the pressure sensitive adhesive dispersion of the invention or fro...
In addition, the LB reacted with the protein molecules and themselves to form a crosslinking structure that increased cohesive strength and improved bond strength. Analogous results were found with Adhesive c. With the addition of PAE to the adhesive formulation, the PAE cross-linked the protein ...
ovata husk mucilage can provide sufficient strength of the bond, preventing easy cohesive failure. The husk remnants might be responsible for the low strain energy density value. It is also possible to estimate the strain energy density value in a pull-off experiment on individual seeds. Assuming...
