Product Description:
WynCoat* SE-4251 is an 80% active dispersion of a very high molecular weight polydimethylsiloxane gum. It is an effective additive for both water-based as well as solvent-based coating systems providing excellent slip, mar resistance, gloss, antiblocking and release effects. Tin-based catalysts are not used in the manufacture of SE-4251.
Typical properties:
Appearance：White, viscous liquid.
Solid content：80％
Viscosity at 25ºC：≥20000 cp.
Application and Uses:
SE-4251 is used as an additive in water as well as solvent-based systems for paint and inks and coatings formulations to provide slip, mar resistance, reduction of coefficient of friction, gloss, anti-blocking and release properties. SE-4251 is particularly effective in solvent-based coatings, especially for leather top coats. Depending of the application, the amount of SE-4251 used ranges from 0.05-3.00% weight percent based on the total formulation. Prior to use, the product can be added as supplied or pre-diluted with water or the typical solvent used in any solvent-based coatings.
