But with four product patents new Rave Microspray aerosol is said to have twice the holding power as conventional hairsprays. So the aerosol actuator must dispense half the amount. "Spray rates of conventional hairsprays are .6 and .75 grams per second. The spray rate of Microspray is between .3 and .4 grams per second" says Anthony Patti research scientist at C-P. The company attributes the low delivery rate to the "configuration of the orifice within the valving system" that's provided by Seaquist Dispensing (Cary IL). Cans are supplied and printed offset in four colors by U.S. Can (Oak Brook IL). Rave Microspray is available in two formulations that mirror the original Rave line. It comes in 3 1/2- and 7-oz sizes and pricing is comparable to 7- and 14-oz sizes of Rave hairspray. It was introduced nationally in February.
