- Fire performance: acrylic is a combustible thermoplastic. Keep away from flames and high-heat sources, and follow applicable building codes.
- Weathering and UV: recommended for indoor and outdoor use; withstands prolonged exposure to sun and the elements. Filters 80–90% of UV light in the 250–400 nm range.
- Thermal movement: expands and contracts 3–8 times as much as glass or metal. A 48 in. panel moves about 0.002 in. per °F.
- Chemical resistance: resistant to mild soap solutions, dilute acids and alkalis, and aliphatic hydrocarbons. Attacked by aromatic solvents, chlorinated hydrocarbons, ketones, esters, lacquer thinners, and high-concentration alcohols.
- Care: clean with soap and water or non-alcohol, non-ammonia-based cleaners. Avoid abrasive cleaners and harsh solvents.

- Fluorescent colors fade quickly under UV exposure.
- Subsurface graphics are protected behind the acrylic face.
- Adhesion verification: cross-hatch tape test per ASTM D3359. Full adhesion develops within 4 hours of proper cure.
