Permabond UV006200250B0101 UV620 UV-Curable Adhesive, 250ml Bottle, Case of 10 Permabond UV620 is a single-part UV-curable adhesive formulated for bonding, sealing, and coating applications requiring a flexible cured bond with excellent optical clarity. Unlike rigid UV adhesives, UV620 cures to a flexible elastomer — making it ideal for applications where differential thermal expansion, vibration, or substrate movement could stress a rigid bond. The 250ml bottle format balances volume and convenience for mid-level production and bench assembly use. Sold in cases of 10 x 250ml bottles.

UV610 cures to a rigid bond, while UV620 cures to a flexible elastomer. Choose UV620 when the bonded assembly will experience vibration, thermal cycling, or differential expansion between dissimilar substrates — conditions where a rigid bond could crack or delaminate over time. Choose UV610 for rigid structural bonds where maximum hardness and chemical resistance are the priority. What UV light source is required to cure UV620? UV620 cures on exposure to UV light in the 320–400nm wavelength range. Cure time depends on UV intensity, wavelength, and bond line thickness. Most applications achieve full cure in seconds to minutes under a suitable UV lamp or LED UV curing system. The adhesive remains workable until exposed to UV light, providing precise process control. What substrates does Permabond UV620 bond? UV620 bonds glass, metals, and many plastics including acrylic, polycarbonate, and flexible substrates. Its flexible cured properties make it particularly well-suited for bonding dissimilar materials or flexible substrates where a rigid adhesive would not accommodate movement or flex. When should I choose the 250ml bottle over the 50ml or 1L options? The 250ml bottle (case of 10) is a mid-volume option suited for regular production use where the 50ml bottle requires too-frequent changeover but the 1L bottle is more than needed. It offers a practical balance between per-unit cost and manageable quantity for bench-level and moderate-volume assembly operations.
