Where To Buy 3m 77 Spray Adhesive

LINK >>>>>

This multi-purpose industrial adhesive spray provides a strong, resilient bond to paper, cardboard, cloth, foil, foam and much more. Ideal for household repairs or DIY projects around the house, arts & crafts projects and more. It is translucent and non-staining, so the bond is as invisible as it is strong.

The 3M Super 77 spray formula is a high tack, fast drying transparent spray adhesive that permanently attaches a variety of materials to wood, metal, painted, and unpainted surfaces. 3M Super 77 features high initial grab with sufficient time to position materials before it has fully set up, and its low overspray mist pattern actuator allows you to pin point areas for adhesive with less waste and cleanup time. Be sure to use only in a well ventilated area.

In order to obtain the best results with your 3M Super 77, be sure surfaces are free from dirt, grease, and moisture. Shake your Super 77 can well just before application, to ensure a strong hold. Align the arrow on the nozzle with the dot on the top of the can. Keep the spray can upright between 6"-8" away from the surface you are spraying. It's recommended to spray a test pattern on a piece of scrap away from the project surfaces. Spray a light uniform coat, keeping the can moving from side to side. Wait 30 seconds before securing the bond between materials. To help alleviate clogged nozzles and save your adhesive for later use, invert can and spray until adhesive stops before storing.

It is important to note that the non-volatile substance of this adhesive is a trade secret and the composition is unfortunately unknown. It could be reasonable to rule out the following substances because the component is categorized as non-volatile: alcohol, mercury, gasoline, and perfume.

The next most abundant component of the adhesive solution is propane. Propane is a naturally occuring gas composed of three carbon atoms and eight hydrogen atoms. Propane is a primary material which is found in petroleum. After the petroleum is extracted from the deep oil fields within the earth, propane is separated from the petrochemicals and refined for commercial use. [15] Some companies who manufacture and sell propane include: Amerigas, Ferrellgas, and Blue Rhino. [6]

The last element of final product to consider is the lid and the spray nozzle of the can. Again with reference from standard aerosol cans, since 3M does not explicitly state what the lid and spray nozzle are made out of, it is safe to assume these components are made of hard plastics. Hard plastics are a secondary material, made by chemical polymerization mechanisms after seperating the hydrocarbon chemicals from natural gas, petroleum or coal into pure steams of chemicals. [14]

In order to address all fields of the life cycle, it must be stated that this is a product has a limited number of uses, due to only so much adhesive being in the can, and there is no maintenance. Therefore, there are no materials involved in the maintenance of the product. The research involved regarding the recycling and management of this product indicates that no raw materials that are involved. The treatment of hazardous wastes after they reach a hazardous waste center is extremely vague and does not provide any details regarding whether the chemicals are neutralized with some other chemical.

Now that sufficient energy has been expended on understanding the raw materials of the 3M Super 77 Adhesive spray, its safe to say the plethora of raw materials which must come together to create this final product, are primarily derived from oil and that there are several energy intensive processes which must occur before the final product can come together.

The aerosol can of Super 77 Multipurpose Spray Adhesive, for example, is composed of raw materials in which the main component of an aerosol can is aluminum which is extracted from aluminum bauxite [6]. From 4lbs of bauxite, approximately 1lb of aluminum is obtained, then dissolved using caustic soda. In this smelting process, other chemical elements such as carbon, sodium, and fluorine are involved. The smelting process requires extensive energy in which the production of 1lb of aluminum equates 15kWH of electricity [13]. During the extrusion process from an aluminum sheet, discs are punched out and with the impact from a high-speed reciprocating punch, a closed end can is formed. After the extrusion process, excessive irregular edges are trimmed to make the can into the even height. Then, the inside and outside of the aluminum can are sprayed with laquer and the entire can is cured with heat, then dried. Throughout the swaging process, the top edge of the can is pressured in approximately 15 steps to form a smooth top and roll flange to accept the aerosol valve or spray mechanism. At the final stage, the aluminum can undergoes a pressure tester, which automatically rejects any defective cans. Lastly, the finished can is transferred via a mode of transportation (often trucks and other vehicles) to warehouses and companies to be commercialized [9].

The chemical content of Super 77 Multipurpose Spray Adhesive is comprised of raw materials with high percentages of acetone, propane, cyclohexane, and petroleum distillates [1]. Acetone, which is obtained through the thermal decomposition of calcium acetate or the carbohydrate fermentation of corn starch or molasses [3]. Propane which is derived from accumulated residual organic material, mixture of raw materials is converted to propane via diagenesis and catagenesis; then follows the separation and collection of the petroleum gases [14]. By drilling oil wells, manufacturers obtain crude oil and wet gas from the hydrocarbon mixture in the underground oil fields. From the overall mixture of oil and gas that is procured from the extraction, about 5% of it is propane while the rest are butane, methane and isobutane [11]. From this process, petroleum distillates which make up for the highest portion of the chemical content of Super 77 Multipurpose Spray Adhesive are also produced [12]. Lastly, cyclohexane is formed via the catalytic hydrogenation of benzene. In order to produce the actual content of the spray, however, a manufacturing process in which the chemicals undergo extensive mixing, distilling, and heating to become the final product, is required [15].

The embodied energy required for the disposal of Super 77 Multipurpose Spray Adhesive depends on whether the product is used up or remains inside in any amount [8]. Since adhesives contain solvents and toxic chemicals that are environmentally hazardous to dispose right away. For the aerosol cans that have unused product left inside, one must empty the can and depressurize it. Then, the aerosol cans can be recycled or disposed of as a household hazardous waste [10]. The energy exerted in emptying, depressurizing, recycling, and transporting the finished product is significant.

When it comes to sustainability of the environment, many opt to use products that serve a purpose to the well being of the Earth. Yet, people do not realize how the simplest products that they utilize everyday, can be the most harmful to the environment when it comes to the waste of the product. 3M is a product company that is animate about making the lives of the consumers that use their products easier and more efficient. Products such as, 3M 77 Adhesive Spray, are utilized by many designers and people on a day to day bases to put up papers, posters, and fliers. The adhesive spray is perceived as a harmless and very useful product, which spares time and works tremendously better than tape or glue when putting together projects, yet the truth behind the adhesive spray is that it consists of many hazardous materials. 3M 77 Adhesive Spray consists of acetone, propane, cyclohexane, petroleum distillates, hexane and incased in a aerosol can. [20] When it comes to the disposal and waste of these ingredients, they each have their own special procedure that has to be done in order to ensure that they are not harmful to the environment.

Hexane is considered as a chemical solvent and is widely used as a cleaning agent, as well as a solvent for glues and adhesives. It is mostly used as the liquid in low temperature thermometers. [4] The most common exposure to hexane is by inhaling it which is extremely dangerous for humans because its can cause mild depression, dizziness, nausea and headaches. Hexane is not as flammable as the other chemicals in 3M 77 Adhesive Spray, but it is sill a flammable substance. The flammable limits depend on the volume of pure hexane but it still pleases a flammable vapor which can be contained by carbon dioxide or dry chemicals. Hexane is expected to quickly evaporate in water and on land and the vapor that is released from the evaporation is hazardous. [14] when disposing of hexane what every can not be saved has to be disposed of in a hazardous waste facility. 59ce067264
