We also realized that a single ink needed to provide adhesion for all types of laminations with high bond strengths
, such as solvent, SAL and extrusion.
Our prior studies have shown that commercial soy protein isolates (CSPI) give very good dry and wet bond strength
for wood bonding, but the strengths are much lower for soy flour, especially under wet conditions.
Effect of silica coating and silanization on flexural and composite-resin bond strengths
of Zirconia posts: An in vitro study.
Researchers examined properties including compressive strength, shrinkage, splitting tensile bond strength
, and freeze/thaw resistance.
For samples modified by the silane coupling agent, higher average values of bond strengths
than those without the modification throughout the entire exposure timeline are evident for the 0-, 4-, and 12-week exposure although the difference at 12 weeks is less than one standard deviation and thus may not be significant.
However pre-curing the adhesives before the CR produced greater bond strengths
to dentine of permanent teeth [Chapman et al.
A holding device was used to evaluate the shear bond strengths
The analysis of this design supplies two points of information: First, that the 8560S has slightly weaker bonds after salt spray exposure than the other two adhesives; and second, that the "dry" compound has higher post-exposure bond strengths
than the "wet" compound when they are applied over the phosphatize-plus-MetalJacket surface treatment, but that relationship is reversed if the surface treatment is grit blasting plus primer.
Laboratory testing of mechanical retention indicates that adhesive-to-bracket bond strengths
are less than those of equivalent-size foil/mesh metal brackets.
It offers good adhesion to synthetic substrates and good lamination bond strengths
The new technique, reported in the March 12 SCIENCE, will be the basis for tables listing bond strengths
in future chemistry books, predicts physicist Paul K.
Improved printability along with the adhesion and wetting characteristics on PET, OPP, PE and nylon substrates now makes it possible to formulate water-based lamination inks with bond strengths
suitable for most food packaging applications," said Richard Grandke, industry manager--Printing & Packaging, Dispersions and Pigments for BASF in North America.
