Aliphatic Urethane Topcoat Photochemical Stability under Shortwave Retail Luminaires
Adding HALS and triazine UV absorbers to aliphatic urethane topcoats prevents shortwave retail LED yellowing and blocks unsaleable display chargeback deductions.
Planogram Lighting Exposure
Meaning
Visual display standards measure the total light energy directed at products on retail shelves over a specific time period. High planogram lighting exposure can lead to color fading, chemical breakdown, or physical damage to sensitive products. This measurement does not apply to items stored in the back of the store away from light sources.
Visual Deterioration
Product presentation requires that the items on display look fresh and appealing to customers. High planogram lighting exposure accelerates the fading of packaging and labels. This reduces the perceived value of the product.
Product Rotation
Vendor agreements specify the lighting limits and product rotation requirements for items on display. If the planogram lighting exposure causes the product to degrade before its expiration date, the supplier can hold the retailer responsible for failing to rotate the stock. Conversely, the retailer can demand that the supplier use more light-resistant packaging to prevent fading.
This dispute is resolved by setting clear guidelines for light levels and display duration in the supply contract. This protects both parties from the financial loss of damaged stock.
Liability Allocation
Regular audits of store lighting help ensure that the light levels do not exceed the agreed limits. This reduces the risk of product damage.
