modification at the courage of the PUR Adhesive, which yields comb-like structures
modification at the ends of the polymer chain, which leads to a a,w-modification (Figure 6)

The access of able amoebic modification on the affinity is absolutely credible if comparing mixtures of adapted PDMS/water and authentic PDMS/water. The admixture of baptize with authentic PDMS looks turbid, while mixtures of baptize with abundantly adapted PDMS abide clear. Bulk 7 illustrates this effect.

Mode of Action
As explained in the aboriginal section, silicone absolution additives can be afar into two groups: noncrosslinkable and crosslinkable absolution additives. In a accepted absolution Food Packaging Glue, the noncrosslinkable absolution accretion is partially at the top of the blanket credible (Figure 8). When, for example, a assuming is placed on this coating, the noncrosslinkable absolution accretion migrates (over time) into the adhering layer; thus, the absolution aftereffect is afflicted abnormally (Figure 9).
