Epoxy glue works on a wide range of materials, including various types of plastics. Notably, its effectiveness can vary depending on the specific type of plastic. Plastics such as PVC, polystyrene, and ABS are generally amenable to epoxy, as it can create strong bonds by curing and hardening, leading to a durable and robust attachment. However, it's less effective on polyethylene and polypropylene due to their resistance to chemical interactions. To enhance adhesion, surface preparation through sanding and cleaning is critical. Epoxy is a two-part system comprising resin and hardener, which, when mixed, undergo a chemical reaction to form a solid bond. It's advisable to check the epoxy product specifications or conduct a small test to ensure compatibility with the specific plastic in question.

Pigments that are stable in heat and acid are integral to various applications, from food coloring to industrial uses. One such pigment is Titanium Dioxide (TiO2), known for its excellent stability under high temperatures and acidic conditions. It is widely used in paints, coatings, and plastics for its superior whitening ability and UV resistance. Another noteworthy pigment is Carbon Black, which maintains its color and form even under extreme conditions, making it popular in the manufacturing of inks, rubbers, and coatings. These pigments are chosen for their ability to withstand harsh environments without significant degradation or alteration in color, ensuring longevity and consistency in the products they are used in.

Egg whites are an excellent source of high-quality protein, containing all nine essential amino acids that the human body cannot synthesize on its own. These amino acids are vital for muscle repair, growth, and other bodily functions. A single large egg white provides about 3.6 grams of protein, which includes a complete profile of essential amino acids. This makes egg whites one of the best dietary sources for obtaining all necessary amino acids. Furthermore, the protein found in egg whites is easily digestible and utilized by the body, making it particularly beneficial for athletes and individuals seeking to build lean muscle mass. However, it's worth noting that some non-essential amino acids and nutrients like vitamin D and choline are more abundant in the yolk, so incorporating whole eggs into your diet can offer additional health benefits.
