UVgrade

UVgrade is a designation used in the materials and coatings industries to denote products that are formulated or processed to resist deterioration caused by ultraviolet radiation. It applies to polymers, resins, coatings, glass and related substrates. A UVgrade material typically features UV stabilizers, absorbers, or hindered amine light stabilizers (HALS) to limit chain scission, cross-linking, and pigment degradation. The term does not correspond to a single universal standard; instead, manufacturers may validate UVgrade status through internal testing or by compliance with third-party standards for accelerated weathering and specified performance criteria for color stability, mechanical properties, and optical clarity over time.

Testing and qualification for UVgrade commonly involve accelerated weathering protocols that simulate prolonged sun exposure, using equipment such as xenon arc or UV lamps, in line with standards like ISO 4892 or related ASTM methods. Performance criteria may include color retention, haze or clarity, gloss, tensile strength, and dimensional stability after defined exposure. Material compatibility with coatings, fillers, and environmental conditions is also evaluated.

Applications for UVgrade materials span outdoor-facing components and end uses where long-term UV exposure is expected. Typical examples include architectural glazing, outdoor furniture, automotive exterior parts, signage, solar-energy components, and protective films for electronics. Selection of a UVgrade material requires considering the anticipated UV spectrum and intensity, environmental conditions, temperature range, and compatibility with additives or surface treatments.

The term can be a marketing label as well as a technical specification, so buyers are advised to review empirical test data, certification documents, and end-use performance rather than rely solely on branding.
