Uniform surface treatment Filler surface can be treated with a silane coupling agent at the monolayer level. Point - Processing agent compatible with respective resin system is viable - Reduced viscosity when mixed into resin - Improved resin adhesion Mechanism Surface treatment improves compatibility with resin. This can reduce resin viscosity. Effects - Difference in interface adhesion strength with resin caused by presence/absence of the silane coupling treatment - Reduced resin viscosity as a result of silane coupling treatment Compatibility of the matrix with the silica surface and resin improves due to surface treatment. Physical properties also improve accordingly. Silane coupling agent examples: Dimethyl silane (CH3O)2Si(CH3)2; Epoxy silane (PPS, Epoxy); Hexyl silane (CH3O)3Si(CH2)5CH3; Phenyl amino silane (PS, PA, Epoxy); Phenyl silane (CH3O)3SiC6H5 (Olefin, LCP, PEEK, PI); Methacry silane (Olefin, ABS, Poly Ester, Acryl); Vinyl silane (CH3O)3SiCH=CH2 (Olefin, (PEEK)); Isocyanate silane (C2H5O)3SiC3H6N=C=O (Urethane). Not only above silane coupling agents, but also various surface treatment agents are available.
