Comparing the Water Repellent Properties of Different Glass Treatment Substances

Overview

Objectives/Goals The objective of my project is to determine the repellent properties of water and water solutions and the products that repels them. Methods/Materials I am using different types of water solutions, plain water, salt water, and acid rain. In the control group I will use a plain piece of glass cleaned with ammonia and alcohol. I will place one drop of water onto the glass. I will raise the glass 1º until the water starts to move. I will measure the angle degree when the water droplet reaches 5cm. I will do this with each water solutions. I will repeat the test thirty times. I will calculate and average the degree of angle of the glass for each test and test variable. Results Rain X has the highest repellent property, when compared to plain glass and other substances. Conclusions/Discussion My conclusion on using different types of water solutions and repellent products can have an effect on the repellent properties. I found that certain kinds of waxes can have different repellent properties in their ingredients. I also found that some liquid detergents can act as a degreaser and aid to the repellent property.
