Don't waste your time with it. It is a flammable hydrocarbon blend. EPA SNAP website See #1 and 2.
Stick with R134a. Dupont SUVA R134a

K5, he is in the Netherlands. They are signatory to the Kyoto protocol, and he is probably encouraged to use HC's for low GWP.
Duracool is indeed an HC blend. Basically R290 & R600, blended to closly match the P/T curve of R12. Since your 1977 vehicle was originally R12, this should work out ok for you. There are some things to remember about Blends, & HC's:
1) HC's are FLAMMABLE. Be sure that you have adequate ventilation when working on your system. Fix all of the known leaks, and be sure to add dye to the system. Do a routine UV inspection at each oil change for refrigerant leaks. If you find a leak, repair it right away - do NOT "top off" the system.
2) Blends tend to fractionate, and may leak one component faster than the other. If you have a leak, the remaining refrigerant must be recovered, and DISCARDED. Fresh refrigerant of the correct blend must be charged. Always charge blends as a liquid, to prevent fractionation during charging.
HC's are compatible with all of the refrigeration oils in use today. You should do a complete flush of the system, and charge the correct oil ammount for your vehicle. Too much oil will hurt cooling, and too little will kill the compressor.
Good luck, and be safe.

Many thanks guys, stay with the 134a and cool it.

Duracool, as I understand it, contains a blend of butane and propane, which is flammable. If an automotive ac evaporator begins to leak, it can be harmful to passengers, not to mention the danger if a spark is present.
