Fish eyes in epoxy are small craters or depressions that occur due to surface contamination, often from oils, dust, or silicone. To fix them, sand the affected area lightly to remove the fish eyes, ensuring the surface is clean. Wipe away any dust or debris with a lint-free cloth and an appropriate cleaner that doesn't leave a residue. Once the surface is prepped, apply a fresh, thin coat of epoxy, ensuring you mix it accurately to avoid introducing new issues. If the problem persists, consider using a product specifically designed to increase the epoxy's surface tension or adding a flow agent to help eliminate fish eyes.

Yes, white glue, commonly referred to as PVA glue (polyvinyl acetate), is indeed a type of polymer. Polymers are large molecules composed of repeated subunits, and in the case of PVA glue, the repeated subunits are vinyl acetate monomers that have been polymerized. White glue's polymer structure gives it its adhesive properties, allowing it to stick materials together effectively. The polymer chains interlink, creating a strong bond as the glue dries and the water content evaporates. Due to its versatility, safety, and non-toxicity, PVA glue is widely used in schools, crafts, and woodworking. Its polymer characteristics enable it to form strong, durable bonds with a variety of porous materials, including wood, paper, and fabric.
2-Butenedioic acid 2Z homopolymer, commonly known as poly(maleic acid), is used in pool maintenance primarily as a water conditioner and sequestrant. This polymer helps in managing pool water chemistry by chelating or binding with metal ions (like iron, calcium, and magnesium) that are present in the water. By doing so, it prevents these metals from forming deposits or stains on pool surfaces and in the plumbing system. Additionally, it can inhibit scale formation, keeping the water clear and reducing the need for harsh chemicals to maintain the pool. Its role in enhancing the effectiveness of sanitizers by maintaining a balanced water chemistry also makes it an essential component in pool upkeep. Essentially, poly(maleic acid) aids in prolonging the life of the pool and its equipment by ensuring the water remains balanced, clean, and free of metal-induced issues.
