Product features and advantages VOK®- P 9909 promotes the compatibility of polyether polyol blends with phase separation tendency, and is used for the production of special polyurethane foam or castables, adhesives, sealants and elastomers. The additive stabilizes the lotion and is beneficial to the treatment of polyether polyol blends. The reaction mixture and final product are more homogeneous. Easier and faster processing results in lower processing costs and better process control. Reduce the cost of packaging and complaint handling.

Recommended use

Polyester

polyether

Hydrophilic diol

Recommended dosage

0.2-3% auxiliary dosage (purchased form) is based on the general formula.

The above recommended dosage is for reference, and the appropriate dosage shall be determined through a series of tests.

Adding method and processing guidance

The additive shall be added to the polyether polyol before the addition of incompatible components.
