Modified silicon micropowder HY-GA-1
Modified silica fume is processed by modifying silica fume particles with surfactants. After modification, the surface of silicon micro powder has organic system affinity chemical groups, increasing the addition amount of modified silicon micro powder and reducing costs. Simultaneously improving the processing technology, achieving better integration with organic systems, and better physical and chemical properties.
Product Features
Low viscosity
Good suspension performance
Easy to disperse
Higher filling ratio
Better compatibility

Notes
Conventional requirements can be met by both the HY-GA series and HY-GB-1. In terms of system specificity, epoxy is preferred, while the rest are applicable;
If the sealing adhesive product has high requirements for system viscosity and related storage stability, further improvements can be made based on actual testing results, such as special silane combined with long carbon chain silane composite modification;
The polyurethane system requires NCO surface customization treatment, with better dispersion effect compared to conventional products.
