Overview
BYK-P 9920 is an additive for improving fiber wetting in fiber-reinforced composites, specially developed for use in ambient curing resin systems. As one of the recommended international brand products in our auxiliary agent range, BYK-P 9920 is supplied with supply chain resource support for formulators sourcing a wetting additive for glass or carbon fiber reinforcement.
Special Features and Benefits
- Improves the wetting of glass or carbon fibers
- Results in less air entrapment and porosity
- Avoids dry spots and reduces the scrap rate
- High content of non-volatile matter, particularly suitable for closed mold processes
- Contains epoxy-functional groups that enable embedding into the matrix
Recommended Levels for BYK-P 9920
The recommended dosage is 0.5 to 3 percent additive, as supplied, based on the total formulation. These recommended levels can be used for orientation, and optimal levels are determined through a series of laboratory tests specific to the resin system and fiber reinforcement being used.
This additive can be incorporated at any time during processing, which gives formulators flexibility in how they integrate it into an existing mixing sequence.
Why Fiber Wetting Matters for Closed Mold Processes
Poor fiber wetting is a common source of dry spots, trapped air, and porosity in fiber-reinforced composites, particularly in closed mold processes where visual inspection during infusion or injection is limited.
Because this additive is formulated with a high content of non-volatile matter, it is positioned as particularly suitable for these closed mold applications, where reducing scrap rate has a direct impact on production cost.
Its epoxy-functional groups are designed to enable embedding into the resin matrix rather than remaining as a separate phase, which is relevant for formulators concerned about the additive affecting long-term mechanical properties of the cured composite.
What to Consider When Sourcing BYK-P 9920
When sourcing a fiber wetting additive for ambient curing resin systems, formulators typically evaluate compatibility with their fiber type, dosage level, and processing method, whether open mold or closed mold. Working with a supplier that can provide consistent documentation and responsive technical support can help reduce qualification time when approving a new wetting additive for a production line.
Because optimal dosage varies by resin system and fiber reinforcement, buyers should run laboratory trials within the recommended 0.5 to 3 percent range before finalizing a dosage for full-scale production.
General Handling and Storage Guidance
As with most specialty processing additives, this product should be kept in its original, tightly sealed container, stored in a cool, dry location away from direct sunlight and heat sources, and used within the manufacturer’s recommended shelf life.
Shelf life and specific storage recommendations vary by batch and packaging format, so formulators should always confirm current shelf life, recommended storage conditions, and any handling precautions against the latest technical data sheet and SDS for the specific batch of BYK-P 9920 they are working with.
