Features and advantages

VOK®- P 9920 is a product developed specifically for fiber reinforced plastics. The additive can improve the wettability of glass fiber and carbon fiber to reduce the entrapped bubbles and pores.

Avoid dry spots and reduce defective rate. Due to its high nonvolatile content, the additive is especially suitable for closed mold molding process. The product contains epoxy functional groups, which can be reacted into the resin system.

Recommended dosage

0.5-3% (purchase form) is based on the total formula.

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

Adding method and processing guidance

The additive can be added at any stage.
