lowUV

LowUV is a designation used to describe materials, coatings, or products designed to limit ultraviolet radiation transmission or exposure. It is not a formal standard, and interpretations vary by sector and region.

Common methods to achieve a lowUV profile include UV-absorbing additives, UV-reflective or scattering coatings, multi-layer laminates, and UV-blocking filters in glass and plastics. The goal is to reduce UV-A and UV-B transmission while maintaining optical clarity, color fidelity, or mechanical performance.

Measurement of lowUV performance typically involves reporting UV transmittance percentage or a UPF-like value. Tests use spectrophotometry across the 280-400 nm range and may follow regional standards (such as ISO or ASTM) or company protocols. Because there is no universal certification for lowUV, reported figures can vary in methodology and rigor.

Applications span building glazing and automotive glass to reduce interior UV exposure; sunglasses and protective eyewear; outdoor fabrics; coatings for art, textiles, and electronics; and packaging films intended to protect contents from UV degradation. In some cases, lowUV designs are paired with other properties such as thermal control or optical performance.

Health and environmental considerations include reduced skin cancer risk, cataract prevention, and slower material fading. Some UV is beneficial for biological processes, so lowUV is a design choice rather than a universal directive. Buyers should verify claims with independent testing results and compare against relevant regional guidelines where available.
