(Also known as Purmelt QR 3317 BR)
TECHNOMELT® PUR 3317 BR is a hotmelt, reactive prepolymer adhesive designed for the graphic industry, particularly for perfect binding and book spine glueing. It offers excellent adhesion to a wide range of paper and materials, including difficult-to-bond papers. The adhesive cures through moisture and reaches 50-80% of its final bonding strength within 12-24 hours, with full curing in 1-2 days depending on environmental conditions.
