Attention: Difference between ACQ and CCA

 CCA--Copper,Chromium and Arsenic Salts

 ACQ--Alkaline and Copper Quaternary

 CCA treatment process is similar to ACQ,but it's free of arsenic.Instead,it uses copper

and ammonium compounds against insect attack,fungi,termites,and wood boring insects.

It's more environment friendly.

 Now in North America and Europe countries,government has banned the use of CCA,

except industrial use,so in the future,ACQ will be mainstream of market.
