Description
HMG AR141 Matt Black is an air dying silicone based paint specifically formulated to enable the dried film to tolerate high temperatures up to 300ºC.
An outstanding feature of AR141 is that gassing and smoking are significantly reduced when it first attains high temperature. This is of particular advantage in the automotive field, and when AR141 is use in confined spaces.
