To clean epoxy resin, first, let any spills fully cure. For uncured resin, use paper towels to remove the bulk, then clean the surface with isopropyl alcohol (rubbing alcohol) or acetone. These solvents break down the resin, making it easier to wipe away. For tools or surfaces with cured resin, try soaking in vinegar for a few hours to soften the resin, then scrub off. Always use gloves to protect your skin and ensure good ventilation when using chemicals. For finished epoxy projects, mild soap and water should suffice for regular cleaning, maintaining the surface without damaging it.
Yes, you can use Drano with PVC pipes, but with caution. Drano, a chemical drain cleaner, is designed to dissolve common clogs like hair, soap scum, and food waste without damaging plumbing. PVC pipes, known for their durability and resistance to corrosion, can generally handle the chemical composition of Drano. However, it's important to follow the product's instructions precisely and avoid overuse, as excessive application may cause unnecessary wear on the pipes over time. Ideally, Drano should be a last resort after trying manual methods such as plunging or using a plumber's snake. Remember, regular maintenance and mindful disposal of waste can prevent clogs, reducing the need for chemical treatments.
Epoxy does not require air to cure. Unlike drying, which depends on the evaporation of solvents into the air, epoxy curing is a chemical process. It begins when the resin and hardener are mixed, initiating a chemical reaction that hardens the mixture. This process is called polymerization, where the liquid components chemically bond to form a solid. Thus, epoxy can cure in the absence of air, and even underwater or in a vacuum, which is a characteristic that makes it versatile for various applications like coating, adhesive bonding, and encapsulating.
