Amidine
Type ID: 3 (pKb ~3-4) 4%
solids
The amidinated positively-charged hydrophobic latex is particularly
suitable for the preparation of latex intermediates. The only
surface functional group present on the particle is amidine,
which is not sensitive to the aggregating effects of polyvalent
cations. These particles are sensitive to negatively charged
contaminants of multivalent anions. Putting these latexes in glass
containers can result in aggregation due to such anions. The
amidine latexes should be used in low to neutral
pH environments. These amidine latexes are available in a range
of sizes and surface charge densities (70-1000 Ų
per charge group).
