Testing Results and Discussions Impact of Contents and Components of the Materials on Coating Performance Impact of the redox system on gelation time Without accelerant, it usually takes several days or some weeks for the unsaturated polyester to solidify under room temperature.
MEKPO/ cobalt naphthenate is a commonly used solidifying system for unsaturated polyester, the amount of the accelerant and solidifying agent has significant impact on the gelation time of the resin and also the features of the solidifying materials.
TiO2 is the most commonly used materials for thermal reflective coatings, which has excellent coverage, and the rutile TiO2 has high weather resistance, the refraction index of which can be 2.8.
Both thermal reflective coating and one kind of common pavement marking materials were selected to carry out comparative study.

The first generation of oil crops, waste oil, sugar, etc. as raw materials is made by the transesterification process.
In addition, the economic viability of biomass fuels research, collection of raw materials is also a concern problems.
The raw materials are mainly three categories: manufacturing of bio-ethanol, starch raw materials, accounts for about 80% of the biological raw materials such as corn (35%), potatoes (45%); carbohydrate raw materials, such as honey, sucrose, beet, sweet sorghum; fiber raw materials, such as tree branches, wood chips, plant fiber quality scraps.

Introduction Aluminium alloys are among the most abundant engineering metallic materials, with a wide spectrum of traditional and sophisticated applications, due to their outstanding properties comparable to steels [1-4].
Material Researched The materials investigated are aluminium-based alloys, procured from Color Metal S.A., with a predominant application in the strength structures of motor vehicles, aircraft, boats and maritime and rivers vessels [1, 3, 13, 14, 16, 17].

The term “direct material energy consumption” stands for the energy consumption for manufacturing and shipping of raw materials by the supplier.
The use of recycled raw materials is only used in conjunction with the energy consumption of the recycling process.
The direct material energy consumption (TEPP-DMatE) of unused raw materials (e.g. due to clippings), components or waste are handled as overhead material energy consumption (TEPP-OMatE).
Therefore, the raw materials 1, 2 and 3 are required, which are purchased from suppliers.
