This version of FastFlex Brushable is the A/B/C system featuring adjustable hardness. The third component, called part “C”, determines the variation in the softness and degree of stretch attainable by the material. When the “C” component is used, work times and demold times will increase.
FastFlex Brushable is a faster variation of our SkinFlex III Brushable. It was developed in response to repeated customer requests for a material system that can be demolded within several hours. With a demold time of two hours or less, FastFlex has accomplished this and much more.
One practical example of how demold time can vary is when FastFlex is applied as a face-coat then backed with polyurethane foam. The heat generated by the foam expedites the curing of the thin skin and demold can be achieved in about one hour. When FastFlex is used as a mold material, the thickness applied will dictate how rapid demold can occur. If an application requires a quarter inch thickness or more of the FastFlex material, demold can often take only 1 1/2 – 2 hours at room temperature.
FastFlex parts are paintable with BJB’s SC-89 stretch polyurethane paint.
