Optimization of a Waterborne Epoxy Coatings Formulation via Experimental Design

Waterborne coatings

Contact: Dr. Charles F. Palmer Ethox Chemicals [email protected] T +1 864 277 1620 They are used in many industrial and architectural applications. The hydrophobic nature of the alkyd polymer makes them good choices when water repellency is important. However, formulating alkyds into low VOC (volatile organic compound) waterborne coatings results in a number of problems, which can be minimised ...

formulation design and optimization of direct compressed tablets of cefuroxime axetil using experimental design

Formulation and optimization of fenofibrate lipospheres using Taguchi's experimental design.

Fenofibrate lipospheres were prepared by the melt dispersion technique. Critical parameters influencing particle size and entrapment efficiency were optimized by applying the L9 Taguchi experimental design. Entrapment efficiency of up to 87 % was obtained for the optimized formulation on increasing olive oil up to 30 % in the lipid carrier. Particle size analysis by microscopy and SEM revealed ...

Thermal properties of siliconized epoxy interpenetrating coatings

This work involves the development of a novel siliconized epoxy interpenetrating coating system using epoxy resin as base, hydroxylterminated polydimethylsiloxane (HTPDMS) as modifier, -aminopropyltriethoxysilane ( -APS) as crosslinking agent and dibutyltindilaurate (DBTDL) as catalyst. Polyamidoamine and aromatic polyamine adduct were used as curing agents for the above coating systems. The th...

Optimization of thermal curing cycle for a large epoxy model

Heat generation in an exothermic reaction during the curing process and low thermal conductivity of the epoxy resin produces high peak temperature and temperature gradients which result in internal and residual stresses, especially in large epoxy samples. In this paper, an optimization algorithm was developed and applied to predict the thermal cure cycle to minimize the temperature peak and the...

Effects of Colloidal Nanosilica on Epoxy-based Nanocomposite Coatings

Epoxy-based nanocomposites were fabricated with different content of colloidal silica nanoparticles such as 10.0, 20.0 and 30.0 wt %, through solution casting. The covalent bonding interfaces, resulting from a ring-opening reaction between silica nanoparticles and epoxy matrix were confirmed by the Fourier transform (FT-IR) infrared spectroscopy. These nanocomposites were characterized for ...
