{"product_id":"tangit-pvc-u-special-adhesive","title":"Tangit PVC-U Special Adhesive","description":"\u003cp\u003eTangit is Henkel's solvent cement for rigid PVC pipework and the one most Kenyan plumbers ask for\nby name. The pack here reads \u003cstrong\u003eTangit PVC-U — Special Adhesive \/ Gundi Spesheli\u003c\/strong\u003e,\n“Henkel: Quality for Professionals”, and on the carton “Special Cement for rigid PVC\nfittings and pipes”. The tin is marked “Made by Henkel Kenya Ltd”, Nairobi. It is a\ntetrahydrofuran-based, gap-filling, thixotropic cement that cures by solvent evaporation, and the pack\ncarries the ASTM D-2564, EN 14680 and EN 14814 marks, a CE mark and a Kenya Bureau of\nStandards Standardisation Mark.\u003c\/p\u003e\n\u003cp\u003eHenkel approves it for PVC-U pressure piping to EN 1452 and EN ISO 15493 and for\nnon-pressure piping to EN 1329 — mains and rising mains, irrigation, borehole delivery lines,\npool circulation, soil and waste. It is not the product for PVC-C or ABS, for which Henkel sells separate\nTangit cements, and PP and PE pressure pipe fall outside its approved scope altogether. Plumbers take the\nsmall tubes for repairs and small-bore work and the tins for a pipeline; note that\nHenkel states tube application should not be used on pipe above d90 mm. From d90 upwards Henkel\nwants the adhesive applied to pipe and socket at the same time by two people, and from d160 a pipe joiner\nused to bring the joint home.\u003c\/p\u003e\n\u003cp\u003eSold by the full carton in five sizes.

Apply a thicker layer to the outside of the pipe, and insert it into the\nfitting without twisting. Remove excess adhesive with absorbent paper. The pack adds three notes:\ncleanliness is essential to making an effective joint, close the tube firmly after use, and ensure\nadequate ventilation while in use.\u003c\/p\u003e\n\u003ch3\u003eSafety — read this before use\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHenkel states plainly: \u003cstrong\u003e“Never use PVC piping systems with compressed air or gas!”\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eTangit is flammable. Solvent vapours are heavier than air, collect at ground level and can form explosive mixtures. Ventilate the work area; no smoking, welding, open flame or sparking there or in adjoining rooms, and avoid any static charge.\u003c\/li\u003e\n\u003cli\u003eProlonged inhalation of solvent vapours may be injurious to health, which is why used tissue goes into a closed container rather than being left lying about.\u003c\/li\u003e\n\u003cli\u003eRemove accumulated vapour before any welding nearby: fill the pipes with water, flush and purge them well.
