The film formation of an acrylate latex with a glass-transition temperature of 38 degrees C has been achieved.:through the use of near-infrared (NIR) radiative heating. A hard crack-free coating was-obtained without the addition of plasticizers. Sintering of acrylate particles was confirmed through measurements using atomic force microscopy. The addition of an NIR-absorbing polymer increased the rate of particle deformation such that it was significantly greater than obtained in a convection oven at 60 degrees C. The results are consistent with a lower polymer viscosity under infrared radiation, according to a simple analysis using a standard model of sintering.
