ProSL was developed for the Garage door industry to ensure that the Springs would never rust.  Garage door springs don't wear out; the springs rust, the rust causes binding, binding causes fatigue, which shortens the life of the spring.  ProSL's advanced formula pentrates between the coils of the spring, coats and protects the steel from corrosion even in salt air environments.  ProSL has been proven to triple the life of garage door cables.  ProSL's formula includes extreme pressure additives that keep the individual thread of the cables from binding up on themselves, extending life of the cable.  First released in 2009, ProSL has not been sold in stores and has had no advertising including our web site.  We are now selling close to 20,000 cans per year with word of mouth the only advertising.
ProSL has been proven in an ASTM B117 salt fog spray test to keep rust at bay for up to 2,700 hours.  It's closest tested competitor lasted almost 250 hours.

Applications

N/A The difference between ALISYN Pro21 synthetic spray lubricant is it doesn't run or drip like the leading penetrating oils. It stays put - and because it is made from the same high quality ingredients used in aerospace applications, it lasts longer than conventional spray lubricants on the market which evaporate within a few days after application.
Pro21 is able to lubricate and perform across a very wide operating temperature range. It will remain serviceable down to as low as -80 ºF and will give long service life at 400 ºF. In special cases, it has been used at 600 ºF. Pro21 holds up under pressure - under tremendous loads Pro21 doesn't break down so it can prevent metal to metal contact making expensive equipment last longer.
In the marine environment Pro21 is tuff on water and rust - long term antirust properties repel moisture providing extra protection from corrosion of metal parts and surfaces. Pro21 has provided antirust protection in steel bearing for over 36 months at 160 ºF and 98 % relative humidity. It exhibits excellent resistance to water washout when used in wet environments. It is non-conductive, and protects electrical equipment from moisture - will not harm wiring or circuitry.
