Y como se puede quitar si alguna vez decido pintar el coche
Muchas graciasAcrysol,Alcohol isopropilico al 50% con agua...
No, no es tan sencillo tengo entendido.
El tema es más complejo. Por lo visto hay "siliconas buenas" y "siliconas malas". Nunca se pueden eliminar al 100 % con ningún producto. Yo desde luego las intentaría eliminar con Acrysol en vez de IPA. ¿Qué productos tienen "buenas" y qué productos tienen "malas"?. Pues ni idea...

Asi es maesal,asi me dijo un chapistas es mas complicado de lo que parece decia que cuantos mas productos que contenga silicona aun lijando hay problemas dar de vez en cuando cera eso es lo que me aconsejabaNo, no es tan sencillo tengo entendido. Yo lo creía así, pero es como si las siliconas se fusionaran con la pintura y en vez de eliminarlas las mueves de sitio. Tal vez lijando a fondo y luego con un disolvente se elimine 100 %, pero vamos, poco más sé...

.Menzerna Polish Systems
THE REMOVAL OF SMEAR FROM POLISHED SURFACES
Polishing is a mechanical process. Silicon is a product that has been designed not to be removed by mechanical abrasion. When using Menzerna, to polish surfaces which have been previously treated with silicon, a smear may result. It is important to understand why this occurs.
CAUSE
There are lots of silicon oils on the market. The properties that make silicon so popular with car detailers, and some auto manufacturers, also make it a very difficult product for the polisher to remove. During polishing, the silicon mixes with the excess paint that is being removed from the surface to form a smear.
Can you remove silicon from a clearcoat completely?
It is impossible to remove silicon from a painted surface without using a chemical process so aggressive that it dissolves the paint. Wax and grease removers will chemically remove one layer of silicon off at a time but are unable to completely remove all the silicon. Tests by Dr Michael Hauber at Menzerna using a spectroscope showed the layers become thinner but the silicon remains. Removing silicon completely can take place over time and involves a lengthy process of oxygen, chemicals, time and sunlight.
PREPARATION
If the car has been treated with silicon, use a wax and grease remover to remove as much of the silicon as possible before polishing. You will not be able to remove it all but it helps.
THE MECHANICAL PROCESS
Polishing is a mechanical process. When a silicon-free polish works on the surface of paint it uses aluminium oxide marbles, suspended in water and hydrocarbons and a mechanical process to abrade the surface of the paint down to the level of the bottom of the scratch. Silicon cannot be removed this way. Silicon is removed by a chemical means and is designed to resist being removed by mechanical means. Instead the silicon mixes with the blend of paint dust and polish powder and it creates a smear on the paint.
We should differentiate between swirl marks in the silicon layer and swirl marks in the paint underneath. Some polishes may appear to remove the swirl marks in the paint but are really only working on the layer of silicon. So the swirl marks in the paint itself remain unaffected by the polishing and reappear after a few weeks, as the silicon is being removed by time.
AFTER POLISHING
If, after polishing, the smear remains, you can use a silicon polish like PO73CP or a silicon wax like PO73 to remove it. However, if you have effectively removed most of the silicon beforehand, this should not be a problem.
Muy interesante esos comentarios sobre las siliconas.![]()
Se echa en falta un poco más de desarrollo, sobre todo cuando nombra los posibles métodos químicos para eliminar las siliconas.
Habrá que ponerse a estudiar un poco este verano![]()
Gracias maesal.
