    • Alkyd baking paints and primers
    • Difficult substrates such as zinc and aluminim

  • Dosage

    With certain types of titanium dioxide and pigments after-treated with zinc oxide, reduction in gloss may occur during storage of the paint. Borchi® Gen HMP-F is a liquid and is therefore easy to incorporate. In most cases optimum results are achievable with an addition of approximately 2 % relative to total paint formulation. Larger amounts may be added under certain circumstances to improve elasticity. Borchi® Gen HMP-F can be added either during manufacture of the paint or subsequently. lf the additive is to be used in water-based paints, it should first be neutralized. We recommend dilution of Borchi® Gen HMP-F with 20 % dimethylethanolamine.

  • 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. Borchi® Gen HMP-F should be protected from exposure to heat during storage. With prolonged storage, signs of crystallization caused by interactions may become evident.

    These disappear again when heated. These soft crystals also dissolve without impairing the quality of the paint when incorporating the additive into the dispersion and during milling.
