Plastisol inks will not dry, but must be cured. Curing can be done with a flash dryer, or any oven. Most plastisols need to reach a temperature of about 180 degrees Celsius (350 Fahrenheit) for full curing. Plastisol tends to sit atop the fabric instead of soaking into the fibres, giving the print a raised, plasticized texture.
where is the heat released up to a certain time , ˙ is the instantaneous rate of heat and is the total amount of heat released in , when the reaction finishes. [ 9 ] Also in this case the degree of curing goes from zero (no bonds created) to one (no more reactions occur) with a slope that changes in time and has its maximum about at half of ...
It is distinct from thermal-oxidation, which can usually take place at less elevated temperatures. [3] The onset of thermal degradation dictates the maximum temperature at which a polymer can be used. It is an important limitation in how the polymer is manufactured and processed.
The PVC coating (vinyl Organisol or Plastisol) contains chemicals to achieve the desired color, water, mildew resistance, and flame retardancy. Fabric can also be manufactured with levels of light transmission that range from very transparent to completely opaque.
