Product description
RESION UV Epoxy Resin (UV Cast25) is a high-quality epoxy casting resin with exceptional UV resistance and transparency. This UV resin is specially formulated to minimise long-term yellowing caused by sunlight. There is therefore no need to add a separate UV stabiliser. This makes RESION UV Epoxy Resin even easier to use and highly versatile. In addition, the improved formula increases the quality of the resin, helping it remain crystal clear for longer and offering improved resistance to yellowing.
Benefits of RESION UV Epoxy resin
- Very high quality epoxy.
- Highest UV resistance on the market.
- Highly transparent.
- Solvent-free.
- Low odour.
- Can be poured up to 3 cm thick.
- Adheres to almost all substrates (like concrete, wood, plastics).
UV resistant resin
RESION's epoxy resin has been extensively tested for UV resistance. By intensively testing the resin for an extended period in a specially developed UV chamber we can guarantee the highest quality and wide applicability. The UV-resistant resin is therefore ideal for artwork, tabletops, jewellery, countertops.

Easy to use
Like all other RESION resins, this epoxy resin is easy to use. Simply mix the base and hardener together according to the ratio indicated on the packaging (100:60) and make sure to stir well for 3 minutes. We also have handy taps for the jerrycans (from 8 kg sets). You can also pour the epoxy into small plastic bottles to easier dispensing. Processing RESION UV Epoxy is very simple if you follow these steps:
- Weigh the base component (A) and hardener (B) thoroughly according to the mixing ratio indicated on the packaging (100 parts by weight of resin to 60 parts by weight of hardener).
- Mix the resin and hardener well for 3 minutes. Also scrape well along the sides and bottom of the mixing cup!
- If desired, add pigments to colour the resin.
- Apply the epoxy to the desired surface (the pot life is 30-60 minutes at 20℃).
- After application, let the UV-resistant epoxy cure for about 12-18 hours before it is manageable (note: after 3-5 days, the epoxy is only fully cured).
