UVPoxy is designed for thin coatings and filling small cracks. It should be used for applications no thicker than a quarter inch. It has a much shorter pot life, which can be as short as 10 to 15 minutes. In contrast, Liquid Plastic is a casting epoxy designed for encapsulation and casting. It has a 3-day cure time and can be poured to any thickness. Liquid Plastic has a semi-flexible finish that is plastic like once cured, as opposed to UVPoxy, which has a harder and more of a scratch-resistant finish.
