Accepta 2116 is a very effective cooling system corrosion inhibitor chemical that is blended with buffering agents.

Accepta 2116 is free from heavy metals or nitrites and chromate.

The actives of Accepta 2116 work with a synergic mechanism to control the corrosion rate by forming an auto-limiting film that has no impact on the heat transfer.  

Accepta 2116 is a high performance corrosion inhibitor that is proven to achieve a protection comparable to that obtained with nitrite-based products, but with the added advantage being much safer and with reduced environmental impact.
