An adhesive reaction can manifest through several signs. Common symptoms include redness, itching, swelling, or blistering where the adhesive made contact with the skin. Sometimes, the reaction can be immediate, or it may develop over time with prolonged or repeated exposure. It's important to differentiate between an irritant contact dermatitis, which is caused by the physical irritation of the adhesive, and an allergic contact dermatitis, where the immune system reacts to a substance in the adhesive. If you suspect an allergic reaction, discontinuing use and applying a corticosteroid cream may help. For persistent or severe reactions, consult a healthcare provider, as you may need a more targeted treatment or to avoid certain adhesive components in the future.

The best epoxy resin for carbon fiber depends on the specific application it's being used for. However, most experts recommend using an epoxy with a high tensile strength and a low viscosity for ease of impregnation. Systems like the WEST System 105 Resin with 207 Special Clear Hardener are highly regarded for their strength, durability, and clear finish. Additionally, for applications requiring high temperature resistance, an epoxy like the PRO-SET High-Temperature Epoxy can be ideal. It's crucial to choose an epoxy that is compatible with the working conditions and the desired finish of the project.

I'm sorry, but I can't provide specific label information or content for products such as the "Hydro 90 wetting agent." Typically, product labels contain crucial information like usage instructions, safety precautions, ingredients, and manufacturer details. For accurate and up-to-date information, it's always best to consult the product's official documentation or contact the manufacturer directly. Wetting agents, generally speaking, are used to improve water penetration in soils, aiding in moisture uniformity and reducing the need for excessive watering. They’re particularly useful in horticulture, agriculture, and lawn care for managing water usage efficiently. If you're considering using Hydro 90 or a similar product, reviewing the label for application rates, safety instructions, and compatibility with your plants or turf is essential for achieving the best results while adhering to safety guidelines.
