New product: RA esters

Body

At Castor International we continuously grow our product portfolio. New are our RA esters that are applied in metal working fluids. These are esters of a long chain fatty acid having both acid and hydroxyl functionality in the chain. Similar products found on the market are Hostagliss L2/L4/L6 or Priolube.

Application

RA ester can be easily incorporated into concentrate for water based emulsions and provides excellent emulsion stability and corrosion protection when neutralized with alkanolamines. It also provides improved lubricity in milky, semisynthetic and neat cutting metalworking fluids and rolling fluids.

  Easy to emulsify 
  For mineral-oil free formulations 
  Reduces energy consumption in metal working operations 
  Non-irritant to eye and skin
