VIIST Anti-Fog Polycarbonate Sheets are optically clear thermoplastic panels engineered with a permanent hydrophilic coating that prevents fogging caused by condensation, temperature changes, or humidity. The sheets retain all the inherent advantages of polycarbonate — impact resistance 250x stronger than glass, lightweight construction (50% lighter than glass), UV protection, and excellent dimensional stability — while eliminating visibility issues in demanding environments.
Key Features ：
Permanent Anti-Fog Coating — Hydrophilic surface treatment (contact angle <10°) disperses moisture into a uniform, transparent filmSuperior Optical Clarity — Light transmission ≥89% with minimal hazeExceptional Impact Resistance — Withstands high-impact applications; 250x stronger than glassAbrasion & Scratch Resistance — Hard coating protects against surface wearUV Protection — Blocks 99% of UV rays, prevents yellowing and extends product lifeChemical Resistance — Withstands disinfectants, oils, and mild acidsTemperature Stability — Performs from -40°C to +120°CLightweight — 50% lighter than glass, reducing handling and installation complexityFormable — Can be drape-formed and line-bent with soft radiiEasy to Clean — Residue-free surface allows cleaning with mild detergents
