Puente Air - Episode 22 - Spray - Urban Rhythm

- Welcome, - Inventions and technology has always been a fundamental part of the development of artistic tendencies though out human history, - Hip Hop culture has not been different, of course... - We have various artistic elements born in the shadows of some invention. - For example, Scratching and Beat Juggling that Djs today do, is depending on the creation of the crossfader. - Or even, the type of sounds that always accompanied the music of the Mcs, is also the result of some fantastic invention made by someone else… The sampler. Which we talked about on earlier occasion. - As you can imagine, Graffiti, Writing, or as some wants to call it, Aerosol Art, is directly linked to spray paint… - Aerosol. - In Barcelona we have the pioneer brand in producing paint specifically made for graffiti. - These are the guys behind Montana Colors. - They gave us their time and took us on a tour in the factory for us to see the process of the production of a spraycan. - Like my brother Cho says: Play video... - The spraycan is basically composed by the container, the can, - the valve - and then the cap, which permits you to get the paint out, and to control the pressure to make lines and such. - The paint goes inside the can, and the gas. - The paint is a mix of different ingredients: - Resin, the solvents, the pigments which are the components that creates the specific color. - Other additives that helps modify other characteristics of the mixture. - The other component of the can is the gas or propellant. - Basically they are LPG, Liquefied petroleum gases. - And there is another gas we use also, the Dimethyl ether. - The development of a aerosol product is very related to what the client wants. - The graffiti writers gives us feedback on what they like in a product and the market wants. - This way we can do different mixtures of paint and gas for different pressure, the relation between them both is to create faster cans or less fast cans, high pressure or low pressure. - The tests we can do as quality control of our paint is all from how much it covers, its shine, the paint viscosity… - We can also do adherence tests, hardness tests, and also tests to see how fast the paint dries. - The design of the product is called lithography which we do before we produce the the can itself. - The canister is made by three parts, first the cutting of the tin itself, and then we make them into cylinders. - Next we weld the parts and staple the two parts together to keep it all closed. - The valve is the part that lets us control the amount of paint that comes out when using the can. - It depends on if it has more or less discharge capacity. - And also we can experiment with the cap, even if for graffiti the caps are used in different ways depending on what type of line you are looking to get. - A very important part is the relation of the gas and the propellant, which permits us to make more precise lines. - The packing of the spray cans is first of all to insert the marbles that helps us mix the paint inside the closed can. - Then we fill the canisters with the paint through a dispenser process. - Now we will attach the valve, the "donut", and then we weld together the can, and last we inject the propellant inside the closed up can. - The top part of the can is put at its place with a stapling machine, and this machine has two functions. - First to close up the valve on top of the canister, and second of all to enter the gas. - And if we did not do the process in this order, the gas would escape. - After the can is welded and ready we make a quality control of its measures, the welding and the hight of the valve. - This is to make sure that the can is airtight so it doesn't lose gas. - The final part is to pack up the product and add the cap that comes included, place the protective plug and label the cans with its characteristics. - On the labeling you can find the cans resistance to sun, the color of the very can, and a scale of the paints covering ability to see with has more or less opacity. - Montana Colors invented the "Donut", with is the plastic top part of the can that shows you what color the canister holds in a fast and comfortable way. - The Donut also contains the blind signal, and the name of the color. - The propellants used for the production are LPG o DME, and are gases used in proportion to the pressure needed for the product to be able to come out of the canister. - The gases and propellants used in our products does not affect the ozone layer. - The product, once used, is 100% recyclable, even the cap and the lids which are of plastic materials. - And also the the canister itself with can be brought to recycling spots, and in some places they even permit you to throw them in regular recycling containers. - To avoid blockage and obstruction its good drain it from paint after having used it. - Draining the can is to turn it upside down and press the cap until only gas comes out of it. - through this process we also clean the cap and we get rid of the remaining paint in the tip of the valve. - Could you imagine it was made like this? Really complicated... - Im really fascinated by this invention, same as the invention of graffiti in itself. - And i don't think that its inventors about a hundred years ago could imagine the things this little thing would provoke in the future. - Ok... - Let's keep painting!
