Application field

Room temperature curing system

Product features and advantages

The wetting and dispersing additive can improve the dispersion of various commonly used fillers, such as calcium carbonate and aluminum hydroxide. It can reduce the viscosity of the filling resin and increase the filling amount. In most cases, the settlement of filler during storage and processing is reduced.

Recommended use

The additive is especially recommended for unsaturated polyester resin, acrylic acid, polyurethane and epoxy resin, and is highly efficient in all application fields.

Recommended dosage

0.5-1.5% of auxiliary dosage (purchased form) is based on filler.

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

Adding method and processing guidance

In order to obtain good performance, the additive should be added before adding solids.

Adhesives&Sealants

Product features and advantages

The additive improves the wettability and dispersion of various mineral fillers, such as calcium carbonate and aluminum hydroxide (ATH), thereby reducing the viscosity and increasing the filling amount. At the same time, the settlement of the filler is usually reduced to prevent the occurrence of the bottom. In many cases, this additive is more effective than VOK ®- Dispatch W966 is more effective.

Recommended use

The additive is especially recommended for adhesives of polyurethane, epoxy and acrylic resin types.

Recommended dosage

0.5-1.5% of auxiliary dosage (purchased form) is based on filler.

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

Adding method and processing guidance

In order to obtain good performance, the additive should be added before adding solids. SMC, wet molding and pultrusion

Product features and advantages

The additive can improve the wetting and dispersion of filler in the mixture of wet molding and HMC polyester molding. The viscosity is reduced, the filling amount is increased, and the wettability of glass fiber is improved. In pultrusion applications, the additive improves the wetting and dispersion of fillers, prevents the settlement of fillers in the immersion bath, and improves the wetting of glass fibers through lower viscosity.

Recommended use

The additive is particularly recommended for HMC polyester molding mixtures, wet molding and pultrusion applications using unsaturated polyester/vinyl ester, epoxy and acrylic resins.

Recommended dosage

1-2% of auxiliary dosage (purchased form) is based on filler, used for HMC molding mixture and wet molding.

0.5-1.5% of auxiliary dosage (purchased form) is based on filler and used for pultrusion application.

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

Adding method and processing guidance

In order to obtain good performance, the additive should be added before adding solids.
