When mixing polyester resin, the ratio is critically important for achieving optimal results. Typically, the ratio is by weight, with the standard being about 1-2% hardener (MEKP) to the resin volume. For example, for 100 grams of resin, you would need 1 to 2 grams of hardener. It’s essential to mix thoroughly to ensure the chemical reaction is uniform. Adjustments might be necessary based on temperature and desired curing time, as warmer conditions may accelerate curing. Always follow the manufacturer’s instructions for best results, and remember proper safety precautions, including using gloves and working in a well-ventilated area. Deviating from the recommended ratio can result in a poor cure, affecting the strength and finish of the final product.

Q why sodium hydroxide is called caustic soda

Sodium hydroxide, known chemically as NaOH, is designated as caustic soda due to its highly caustic nature, meaning it can burn or corrode organic tissue by chemical action. This strong alkaline compound, when dissolved in water, generates a significant amount of heat and forms a caustic solution capable of breaking down fats and proteins, a characteristic that makes it highly effective in cleaning and clearing blocked drains. Its causticity, therefore, is not just a chemical property but also a defining characteristic of its utility and danger, which is reflected in the name ‘caustic soda’. This name serves as a warning and a descriptor of its chemical behavior, distinguishing it from substances that are less hazardous.

Q is caustic soda alkaline or acidic

Caustic soda, also known as sodium hydroxide (NaOH), is a strong alkaline substance. It has a high pH value, much above 7 (which is neutral), typically ranging from 12 to 14. This indicates a strong base, capable of neutralizing acids. In industrial and chemical processes, caustic soda is used for various applications due to its alkaline properties, such as soap making, paper manufacturing, and water treatment. Being highly corrosive, it can cause severe burns upon contact with skin and should be handled with utmost care. Its alkaline nature makes it effective in breaking down complex molecules, including organic matter, and it is also used in household drain cleaners for this reason.
