PV-RH275 back rail adhesive is now available for solar module manufacturing. The reactive hot-melt adhesive recently passed the critical performance and long-term durability tests of the IEC 61646 standard. TÜV RheinlandTM, a global provider of technical, safety and certification services, conducted the tests of PV-RH275 applied to a customary rectangular (SI_S4) sized module to determine if the one-part reactive hot-melt system meets the standards of IEC 61646. According to testing performed by TÜV, PV-RH275 fulfilled the mechanical load test requirements of the IEC 61646: 2008 (loads of 2,400 Pa and 5,400 Pa), following 1,000 hours of damp heat testing at 85% relative humidity and a temperature of 85°C.

PV-RH275 is formulated for fast processing and curing. It bonds quickly after the adhesive-coated back rail is attached to the module. Within minutes, the solar module is ready to box and ship. Over time, the adhesive bond strengthens, making it extremely durable during varying weather conditions of high heat and humidity, snow, or wind.
