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 used as a wetting and dispersing additive in fiber reinforced spray and hand paste resin filling systems and cobalt promoted putty formulations, especially in unsaturated polyester resins. It is also recommended for acrylic resin, polyurethane resin system and epoxy resin.
Recommended dosage
0.5-1.5% dosage of additives (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.
Recommended use
The additive is recommended for adhesives of polyurethane, epoxy and acrylic resin types.
Recommended dosage
0.5-1.5% dosage of additives (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.
