Nothing can stop any epoxy from yellowing over time, but Alumilite has added UV protection to this formula to stall the yellowing process, ideal for coating over white backgrounds. Durability is important when it comes to epoxy resins and you can achieve that with Amazing Clear Cast Plus, which cures to a durable and high gloss finish every time and is FDA compliant. Spice up your craft by adding some color to it. You can mix it with any Alumilite dyes, alcoholic inks or other non-water-based colorants, excellent for customizing tumblers. There's no limit to what you can do with this crystal clear epoxy resin set. Use it to glaze tables, wood or bar tops. Use it to encapsulate small objects like flowers, insects, and coins into your silicone molds. Everyone will appreciate the simplicity of 2-part kit. Made in the USA.
