On exposure of the applied Silcoset 153 to atmospheric moisture, the curing process begins with the formulation of surface skin and progresses right though the material with the elapse of time. Cure rate is dependent on humidity and temperature but under normal conditions a tack free surface will be obtained in 10 to 20 minutes and a 4 mm thickness will be cured within 24 hours. The maximum thickness to be cured in one operation should not be greater than 12 mm if only one surface is exposed to atmosphere. The rate of cure can be increased by heating, but temperatures in excess of 80 C should not be used with Silcoset 153 thickness greater than 0.3 mm. It should be noted that conditions of high temperature and low humidity during cure can adversely affect the adhesion and physical properties of Silcoset 153. Silcoset 153 liberates traces of acetic acid during the curing process. Under normal conditions the acetic acid is rapidly dispersed, but in confined situations it may be necessary to provide supplementary ventilation. Silcoset 153 is odourless and taint-free when fully cured.
