BYK® -P 9909

Technical Datasheet | Supplied by BYK
BYK®-P 9909 by BYK is a processing additive/compatibilizer for polyurethane systems to prevent phase separation of polyol blends in storage tanks. It increases process reliability and reduces application time on site. It is a solution of an ammonium salt of an acrylic acid copolymer. It promotes the compatibility of polyol blends that have a tendency to phase separate and that are used to produce special polyurethane foams or CASE applications. The additive stabilizes the emulsion and therefore facilitates the handling of polyol blends. The reactive mixture and the final product are more homogenous. The easier and faster handling results in lower processing cost with better process control. The costs for packaging and complaint handling are reduced. BYK®-P 9909 is especially recommended for polyether & hydrophilic glycols and recommended for polyester applications. The recommended level is 0.2-3 % additive (as supplied) based on the total formulation. The shelf life of this product is 36 months.
