  • Dosage

    Borchers® AF T can be used as supplied or thinned at the approximate ratio of 1:1 to 1:10 in organic solvents like alcohols, hydrocarbons, esters, etc. It is best added during the manufacturing process to prevent foam stabilization. Recommended levels are 0.01 – 0.50 % as supplied by weight of the formula. The amount must be experimentally determined because it will depend largely on the amount of foam present. 

  • Storage

    Protect from the effects of weathering and store at temperatures between 5 and 30 °C. Once opened, containers should be resealed immediately after each removal of the product.
