The spreading of a small epoxy resin droplet (l.5tL) on a glass surface was examined with the objective of developing a new type of hydrophobic polymer coated glass which has the ability to reduce heat gain inside a building. The study covered three main aspects; the spreading kinetics of epoxy resin on a glass surface, the hydophopicity of the developed polymer-coated glass surface, and the reduction of solar radiation of this surface, As wettability and spreading phenomena arc a fundamental prerequisite for coating, the spreading kinetics of different curing agent concentrations (15:200, 18:200, 21:200) of epoxy resin on the glass surface (soda lime), were studied. AU different curing agent concentrations of epoxy exhibit good spreading behavior. As the curing agent concentration of epoxy resin increases, the spreading kinetics on the surfaces decreases.
The hydophopicity of the polymer-coated glass surface was tested and it was found that epoxy resin surface has the ability to repel water. Dip-coating techniques provided a polymeric coated glass surface that had a transparent appearance giving the natural look of glass. This allowed the transmission of natural visible rays providing natural daylight. The developed polymer coated glass surface was found to reduce the heat absorbed due to solar radiation. A Kipp & Zonen Pyranomcter CM11 in conjunction with a solar integrator were used for measuring the solar radiation absorbed by the glass surface. The results showed that the epoxy coated glass surface provided heat gain reduction ranges of between 23% and 60% depending on the solar irradiance.
