Crosslinkers for UV Powder Coatings - PCI Mag
2006/1/18· UV powder coatings are making strong inroads into the powder coatings market, especially for temperature-sensitive substrates. The existing UV-curing powder coatings systems generally build on two binders. This paper presents an option to the existing systems and consists of using unsaturated amorphous or amorphous-crystalline polyesters comprising maleic/fumaric moieties …
DSC measures the difference in the amount of energy required to heat a sample and a reference at the same rate. By using this technique, we are able to measure various properties including phase transition temperature (whether such a transition is from solid to liquid, amorphous to crystalline, or magnetic to non-magnetic), latent heat of transformation, and specific heat capacity.
Powder coatings are dry powder polymers that have a particle size in the range of 30 to 50 µm. This type of coating is usually applied electrostatically as a free flowing dry powder and then heated to flow into a hard finish. These coating materials can be
Advanced Nanocomposite Coatings of Fusion Bonded …
The performance of fusion-bonded epoxy coatings can be improved through advanced composite coatings reinforced with nanomaterials. Hence, in this study a novel organic-inorganic nanocomposite finish was designed, synthesized, and characterized, achieved by adding -aminopropyltriethoxysilane modified silica nanoparticles produced via sol-gel process in epoxy-based powder.
