Molecular Sieves – An Original Nanomaterial
(Apr 23, 2008)
Molecular sieves may be the original nanomaterial. They have been used for decades by adhesive and sealant formulators to modify compounds on a nano - or molecular level. They are primarily used as...
Design Issues for Tissue Adhesives
(Apr 16, 2008)
The heroic tale of how humble superglue saved lives in Vietnam by providing a quick way to close wounds and stop bleeding is surprisingly widely told – and almost too good to believe1. Today various...

Methods of Controlling Static Charge
(Feb 27, 2008)
Static electricity can be a major problem with certain adhesive products such as pressure sensitive coatings, laminating films, and other sheet or film products. Static electricity generally does not...
(Feb 13, 2008)
Most tests of adhesive strength examine linear or peel stress1, which induce cracking and drive adhesives to the point of failure. When cracks develop either adhesive or cohesive failure can result...
Vinyl Ester Adhesives
(Jan 16, 2008)
Vinyl ester resins are thermosetting resins that consist of a styrene monomer and the addition products of epoxy resins and methacrylic acid. As a result, they are sometimes referred to as "epoxy...
Agglomeration in formulation and how to deal with it
(Jan 4, 2008)
When I first learnt about adhesive formulation, one of the less technical rules-of-thumb that I was given compared my employer's processes with cake-baking. Polymer fluids were analogous to milk and...
