Baysilone Paint Additive MA Low molecular weight methyl polysiloxane Bayer-Börchers Flow / Levelling agent >> Silicone Alkyd Resins Polyester Coatings >> UV / Radiation Curing Baysilone®- Paint Additive MA 5 Low molecular weight methyl polysiloxane with high volatile siloxanes content, 100% active ingredient Description Levelling and anti-floating agent Solubility aliphatic hydrocarbons soluble aromatic hydrocarbons soluble alcohols soluble / partially soluble esters soluble ketones soluble glycol ethers soluble / partially soluble glycol ether acetates soluble Decalin / Tetralin soluble styrene soluble water insoluble Properties Baysilone®-Paint Additive MA is a very effective levelling agent. lt reduces surface tension and prevents horizontal floating of pigments. Applications Baysilone®-Paint Additive MA is very well suited to use in polymers which dry physically. lt acts as a very effective flow-promoter in numerous alkyd paints. In unsaturated polyester paints containing paraffin, it promotes uniform floating of the paraffin and deaeration. Its binder compatibility is limited. Addition rate 0.01 - 0.05% based on solids content; 0.001% in unsaturated polyester paints containing paraffin. Recoatability Direct impairment of over-paintability and adhesion is unlikely at the recommended addition rates. Since such defects, the causes of which include over-stoving, may sometimes be considerably intensified, we recommend that the product is used primarily in top coats.
