Metalset ® A4 adhesivo epoxi- relleno de Aluminio

Metalset A4 ® es un potente adhesivo epoxi que ha sido utilizado durante años por los militares de EE.UU, así como por todas las grandes aerolíneas y fabricantes de automóviles en el mundo. A4 se utiliza en cientos de aplicaciones industriales y ofrece una excelente adhesión a superficies porosas y no porosas. Se puede aplicar en superficies verticales manteniendose en su sitio. Metalset A4 ® cura durante la noche con una contracción insignificante.

Una vez curado, Metalset A4 ® tiene unas buenas cualidades de mecanizado (lijado, taladrado, roscado) y es resistente a los álcalis, ácidos diluidos y disolventes. Entre otras aplicaciones se utiliza para detener fugas en tuberías, válvulas y tanques (por ejemplo en depósitos de gasolina de automóviles), para unir superficies iguales o desiguales, como relleno de juntas metálicas, abolladuras, etc. También se utiliza para fabricar pernos de anclaje en madera y hormigón y para reparar superficies metálicas. El tiempo de curado de Metalset A4 ® es de 16 horas.

Instructions

A clean, dry surface is a necessary prerequisite for adhesive bonding. Adhesives will stick to either the surface of which a bond is desired or to that film of extraneous material directly on that surface. Rarely can a structural adhesive penetrate through surface contaminants to provide an optimum bond on an unclean surface.

Porous materials are simple to bond, provided they are dry. The surface should be sanded till clean and free from dust. Non-porous surfaces, such as found on metal and plastic materials, should be degreased, dried and roughened by sanding, sandblasting or chemical etching. The etched or sandblasted surfaces should be covered within a few hours of treatment to prevent contamination.

Handlers should wear clean cotton gloves to prevent body oils from contaminating the clean surfaces.

Epoxy adhesives do not perform well on metals such as nickel, chromium, tin or zinc nor on soft thermoplastics like polyethylene.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

MEASURING & MIXING - Measure equal amounts of Parts A and B (or 2A:1B) by volume into a clean mixing container. Mixing tools and containers should be clean and made of metal, glass or plastic. After dispensing required amount of Parts A and B into mixing container, mix thoroughly for 3 minutes making sure that you scrape the sides and bottom of the mixing container several times.

Application - Apply to prepared surface and let cure for 24 hours. Applying mild heat will cure EA-40® faster – 150°F/65°C for 6 hours.

Post Curing - After EA-40® has cured at room temperature, heating the epoxy to 150° F (65° C) for 4 to 8 hours will increase physical properties and performance. Let cool to room temp. before moving bonded substrates, machining, etc.

To Attain Maximum Heat Distortion Temperature - let cure for 24 hours at room temperature, heat cure for 2 hours at 250°F (122°C).

At mix ratio 1A:1B – HDT will be 163°F (73°C).

At mix ratio 2A:1B – HDT will be 217° F (103 °C)

Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.

Store and use material at room temperature (73°F/23°C). This product has a limited shelf life and should be used as soon as possible.
