A number of these hybrid PUD/styrene-acrylic (PUD Acrylic) blended products are supplied as a two-component material; an aziridine is added on-site to enhance the performance, particularly the stain resistance, which was sacrificed for lower cost.
For example, ERISYS GA-240, a tetra-functional epoxy reactive modifier, can serve as a drop-in crosslinker replacement for polyfunctional aziridine (PFAZ) in coatings and adhesives.
Aziridine 2-methyl- is an imine which is widely spread in ten sampling stations out of thirteen (Table 7).
Polyamines can be prepared hy ring-opening polymerization of aziridine and aziridine through a cationic mechanism, as the three- and four- membered rings contain enough ring strain to be polymerizable (13).
They were then formulated into ambient cure clearcoatings with aziridine crosslinking.
2]-absorbing substance--one that binds the gas via a chemical reaction--by painting an organic compound called aziridine on a wafer of silica.
Thus, initial studies have focused on an N-triphenylmethyl substituted aziridine.
Her interests are in catalysis as well as the synthesis and applications of aziridine scaffolds.
To further emphasize this point a traditional two-component finish was modified to a semi-gloss level in separate formulations using the matte PUD and silica and crosslinked with both isocyanate and aziridine.
To enhance the performance of WPU, these polymers have been reported to be crosslinked with aziridine, (6) carbodiimide, (7) amino-formaldehyde and melamine-formaldehyde resins, (8) etc.
