The second objective was oriented, but equally valuable product attributes like raw material supply security. We have seen that hydrogenated hydrocarbon tackifiers offer a good value package for most high-end packaging applications. They compare favorably to tall oil rosin esters in terms of adhesive performance and offer advantages such as odor, molten stability, raw material and tackifier supply security, global supply and environmentally friendly process features.

SS8, which is derived from sugar and soybean oil, is 100% biobased, nontoxic, and biodegradable. As a result of its unique molecular architecture, it was expected that SS8 would be an excellent reactive diluent for alkyd coatings. The experiment conducted basically involved the incremental replacement of the MOA with SS8, while maintaining essentially equivalent solution viscosity. The properties of cured coatings were determined using industry standard methods. In general, it was found that SS8 could be used to reduce volatile organic compound content of the coatings, while also reducing drying time (i.e., tack-free time), increasing solvent resistance, and increasing impact resistance. Of the properties measured, the only cured film property that was negatively affected by the use of SS8 was the König pendulum hardness. However, the reduction in König pendulum hardness was only observed when the amount of MOA replaced by SS8 was greater than 10 wt%. Overall, these initial results suggest that SS8 is a very good reactive diluent for alkyd coatings. Note de contenu : - Fig. 1 : The chemical structure of a number of molecules that have been described in the literature as potential reactive diluents for alkyd coating
- Fig. 2 : representative chemical structure of an SS8 molecule. It should be understood that the chemical structure of the soy-based fatty acid ester molecules around a single sucrose core will vary and the distribution will depend on the fatty acid ester profile of the soybean oil used as a starting material
- Fig. 3 : Tack-free time as a function of SS8 content in the coating. Tack-free time was determined according to ASTM D1640
- Fig. 4 : Pendulum hardness as a function of SS8 content for the MOA/SS8 coatings
- Fig. 5 : The variation in solvent resistance with SS8 content for the MOA/SS8 coatings
- Fig. 6 : Direct impact resistance as a function of SS8 content for the MOA/SS8 coatings
- Fig. 7 : The variation in reverse impact resistance with SS8 content for the MOA/SS8 coatings
- Fig. 8 : relative comparison of the properties of coatings 90/10 MOA/SS8 and 75/25 MOA/SS8 to coating 100/0 MOA/ SS8. The spider chart shown in this figure was constructed such that the data point farthest from the center along any given axis is given a value of 1.0 and corresponds to the coating that had the most desired value for that property. For example, coating 75/25 MOA/SS8 exhibited the highest
solvent resistance, highest direct impact resistance, highest reverse impact resistance, lowest VOC content, and shortest drying time (i.e., tack-free time). As a result, a value of 1.0 was assigned to each of these properties for coating 75/25 MOA/SS8. However, for pendulum hardness, coating 100/0 MOA/SS8 exhibited the highest pendulum hardness, and, thus, a value of 1.0 was assigned to this coating on the hardness axis. The other two data points on each axis represent the magnitude of the property for the other two coatings as a fraction relative to the coating with the most desirable value for the property
