{"product_id":"pegamento-termofusible","title":"Hot-melt adhesive","description":"\u003cp\u003eSealing seams, overlaps and patches of HDPE geomembrane, composite membrane and drainage boards on site —where you can't always bring wedge or extrusion welding equipment and where the joint must end up as watertight as the liner itself— calls for a hot-melt adhesive formulated for geosynthetics. This hot-melt adhesive —also called hot-melt glue for geomembrane or geotechnical adhesive— comes in a \u003cstrong\u003ebucket with a built-in electric heater\u003c\/strong\u003e and is designed, in the MOLTEXO line, to permanently bond waterproofing membranes, composite membranes and drainage boards with a high-strength, low-permeability joint.\u003c\/p\u003e\n\n\u003ch3\u003eKey benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrong\u003eA joint as watertight as the liner:\u003c\/strong\u003e permeability coefficient ≤3.5 × 10\u003csup\u003e-12\u003c\/sup\u003e cm\/s on a PE membrane joint, on par with the base material.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eHigh bonding strength:\u003c\/strong\u003e adhesion ≥1.5 MPa and shear strength ≥0.4 MPa (high-strength versions ≥0.8 MPa); often the base material fails before the joint.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eWithstands water immersion:\u003c\/strong\u003e strength retention ≥80% after 7 days submerged, suitable for permanent hydraulic works.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eHandles hydraulic-works and landfill pressure:\u003c\/strong\u003e watertightness pressure ≥0.8 MPa with a 5 cm bonding width.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eBucket with built-in electric heater:\u003c\/strong\u003e when you open the lid, the adhesive already has two heating elements (probes) inserted and a plug with cable ready to connect; it melts inside the bucket itself, with no need to transfer it to another container.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical indicators (TDS)\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrong\u003ePeel strength (2 h):\u003c\/strong\u003e ≥4.0 kN\/m (or base material failure); high-quality products reach 5–6 kN\/m.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eShear strength (2 h):\u003c\/strong\u003e ≥0.4 MPa (or base material failure); high-strength versions ≥0.8 MPa.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eAdhesion strength:\u003c\/strong\u003e ≥1.5 MPa; retention ≥80% after 7 days of water immersion.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003eWatertightness pressure:\u003c\/strong\u003e ≥0.8 MPa (5 cm bonding width); suitable for water conservation and landfill anti-seepage.\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003ePermeability coefficient:\u003c\/strong\u003e ≤3.5 × 10\u003csup\u003e-12\u003c\/sup\u003e cm\/s (PE membrane joint), equivalent to the base material.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications and typical uses\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSealing overlaps and joints of HDPE geomembrane where welding is not applied.\u003c\/li\u003e\n  \u003cli\u003eBonding composite membrane (geomembrane + geotextile) and patch repairs.\u003c\/li\u003e\n  \u003cli\u003eJoining drainage boards and sheets and their accessories.\u003c\/li\u003e\n  \u003cli\u003eRepairs and finishing in water-conservation and landfill anti-seepage projects.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eQuality and durability\u003c\/h3\u003e\n\u003cp\u003eA generic adhesive fails when it loses grip under prolonged immersion, when the joint becomes more permeable than the liner, or when it doesn't reach a uniform application temperature.
