AIRLESS SPRAY
Thick Film Obtained With One Coat
MORE Control in spraying and the application of a thicker film in one coat are two advantages claimed for an airless spray outfit developed by Iwata Air Compressor Manufactur- ing Co., Ltd., 1-6 Ebishu-Minami, Shibuya-ku, Tokyo. Loss of paint is said to be considerably less than with air spray units.
The paint pump is operated by an air motor from a 70 p.s.i. supply. It compresses the paint which is then led to a paint chamber. This system prevents pulsations in the output of the gun.
Maximum output is 86 cu. in. a minute and maximum pressure 1,960 p.s.i. The paint container holds 6.6 gals, and the total weight of the unit is 73 lb. Power requirements

CONCRETE PRODUCTS Release Agent Prevents Bonding
for
TWO chemical release fluids concrete a bond breaker and a softener have been developed by T.B. Hampton (Australia) Pty., Ltd., 3 Short Street, Chatswood, NSW.
The bond breaker reacts chemical- ly with the alkali in the concrete to produce a release agent.
This pre- vents bonding between the poured concrete and the form.
The softener, sprayed on to the interior of mixers and other concrete handling equipment, prevents residue from hardening and bonding to metal.
