Facebook← Back to Which resin should be used for polystyrene?
Sunlight exposure can cause polystyrene resin projects to turn yellow or lose their clarity over time. Let’s explore why UV resistance is a key factor in resin choice and how to select products that keep your work looking its best.
Why Does UV Resistance Matter?
Resins without UV filters are likely to discolour, especially when displayed in bright or outdoor areas. Yellowing not only affects appearance but also reduces the lifespan of both decorative and functional pieces. Integrated UV resistance slows this process, helping your project maintain its original look for longer.
Choosing the Right UV Resistant Resin
Look for clear epoxy resins that specifically mention UV filtration. For polystyrene projects under 2cm thick, Trasparente Multipurpose Clear Epoxy Resin is a suitable choice, offering a built-in UV filter for better protection. For thinner coatings, “Art Pro” is formulated for artists needing a glass-like finish with added UV resistance. If you’re working on smaller or indoor projects and prefer odourless resin, “Icrystal” may be ideal, also boasting UV filtering properties.
When Does UV Resistance Matter Most?
- Projects displayed in direct sunlight such as windowsill art or outdoor ornaments
- Items intended to keep a crystal-clear or transparent finish, like jewellery or embedded decorations
- Functional pieces where clarity and durability are vital
