Dynoadd F-403 Polyester-based siloxane modified Dynea Flow / Levelling agent Slip control Surface conditioner, miscellaneous >> Anti-crater aid Surface conditioner, miscellaneous >> Gloss control Wetting agent/ Wet edge enhancer Coatings >> Solventborne Automotive OEM Automotive refinishing Wood & Furniture Coatings Soluble in aromatic hydrocarbons Insoluble in water Soluble in alcohol Soluble in glycol ethers Dynoadd F-403 is a polyester-based, siloxane modified additive that effectively controls surface tension in solvent based coating systems. Dynoadd F-403 gives excellent flow, leveling and overspray cratering resistance to spray applied coatings. The additive significantly improves film appearance at low dosage levels. Enhanced surface slip is gained with increasing level of addition. Dynoadd F-403 is delivered as a 50% active solution in dipropyleneglycolmonomethylether (DPM). Dynoadd F-403 is completely soluble in solvents like aromatic hydrocarbons, glycol ethers, esters and alcohols. It has a limited solubility in aliphatic hydrocarbons, and is not soluble in water. It enhances flow/leveling and gloss in clear coats and pigmented systems, prvents craters and orange peel, improves substrate wetting, improves surface slip. It is used in wood coatings and automotive OEM repair/refinish. Polyester-based siloxane modified additive. Controls surface tension in solvent based coating systems and improves film appearance at low dosage levels. Used in wood coatings and automotive OEM repair/refinish.
