Abstract : A high wind speed rain spray tester was constructed to replace the AN-R-24 rain spray test apparatus used in previous work. The durability of a number of rain repellent formulations whose life on the AN-R-24 test apparatus had been determined was evaluated on the new machine. Investigation of the action of colloidal silica and other finely divided powders in combination with silicone oils resulted in formulations which show improved repellency particularly after exposure to heat.
