Intercom Ecostick 1816B Leather Glue

Intercom Ecostick 1816B Water-based polyurethane adhesive from Intercom in Montespertoli, just outside Florence, made for the Italian leather goods trade. High strength, cold bonding, and it dries clear without yellowing. We bottle the 250 ml, 500 ml and 1 L sizes here from Intercom's bag-in-box, and the 5 kg comes in Intercom's own sealed bag. What it's for Permanent bonds on leather, including oily and waxy leathers up to 15% fat content, and on synthetic leather, fabrics, linings, card, PVC and nylon. Its low viscosity spreads thin and even, which makes it especially good for flat work — card slots, feather-edged straps, linings and turned edges. Where you're stitching afterwards, it holds the layers precisely while you sew. How to use it Brush a thin coat onto both surfaces and let it dry until the white turns clear, a few minutes. Bring the pieces together within 20 minutes of drying and press firmly — a roller or clamp helps. If you miss the window, warm the glue line to 60–65°C with a heat gun and press again. Full strength develops over 48 hours. Clean brushes in water while the glue is still wet. The 5 kg bag The 5 kg comes just as Intercom packs it for the trade: one sealed 5 kg bag, the same bag that goes into their 10 kg bag-in-box. That's about 4.7 litres. Decant what you need into a smaller bottle as you work, and keep the bag closed between uses. If you'd rather have it in bottles, we can split the 5 kg into separate bottles for you before it ships. Just leave a note with your order, or send us a message, telling us the sizes you'd like. How far it goes At Intercom's recommended 50–150 g/m², a 250 ml bottle covers roughly 2 to 5 square metres of glued surface, and the 5 kg bag roughly 33 to 100. That's a good many wallets. Technical data Solids about 52%. Density 1.06 g/cm³. Viscosity 850–1150 mPa·s. pH 6–8. Full technical and safety data sheets below. Notes Keep it sealed between 5 and 30°C, out of direct sun. Shelf life is 12 months from manufacture. The adhesive is damaged irreversibly if it freezes, so in winter please don't leave it on a cold doorstep — and if it arrives frozen, tell us and we'll make it right.
