What is UV Degradation? UV degradation can be a primary factor in signs substrates yellowing over time. The simulation shown easily demonstrates how other styrene facers can quickly degrade and yellow simply from exposure to interior lighting. UV degradation occurs due to oxidation of polymers within the plastics that make up sign substrates. Substrate yellowing […]
