The use of inorganic fillers in resins and sealants such as rubber and plastic is increasing, while troubles caused by moisture content are also on the rise. In general, the particle surfaces of inorganic fillers are hydrophilic, which can lead to unexpected issues during use as they adsorb moisture from the air while being stored. The "WAC Series" absorbs moisture in environments that dislike moisture and exhibits the same effects as when the material is dried, functioning as an additive antifoaming agent. Due to surface treatment, dispersion and compatibility with resins are improved, and an enhancement effect on the fluidity of sealants is expected. 【Features】 ■ Absorbs moisture in environments that dislike moisture ■ Exhibits the same effects as when the material is dried as an additive antifoaming agent ■ Improved dispersion and compatibility with resins due to surface treatment ■ Expected enhancement effect on the fluidity of sealants *For more details, please refer to the PDF document or feel free to contact us.

The "AHT Series" is a composite filler made of talc and calcium carbonate. When only talc is added to olefin-based resins to enhance rigidity, it has the drawback of reducing impact resistance. This issue is addressed by our product. The filler is dispersed at the primary particle size, allowing for the expected improvement of both the rigidity of talc and the impact resistance of calcium carbonate, which have opposing mechanical properties. Furthermore, since the surface is modified with organic agents, it offers excellent dispersibility and is expected to improve workability. 【Features】 ■ Filler is dispersed at the primary particle size ■ Expected improvement of both opposing mechanical properties of talc and calcium carbonate ■ Excellent dispersibility and improved workability *For more details, please refer to the PDF document or feel free to contact us.

The "SCP-H Series" is a surface-treated calcium carbonate using a special coupling agent. When blended with thermosetting resins such as unsaturated polyester and acrylic resin, it imparts rigidity and teachability to the thermosetting resin, provides a reduction in viscosity for the compound, enabling high filling, and improves the contamination resistance and acid resistance of the molded products. We offer packaging forms such as flexible containers and paper bags. 【Features】 ■ Imparts rigidity and teachability to thermosetting resins ■ Provides a reduction in viscosity for the compound, enabling high filling ■ Improves contamination resistance and acid resistance of molded products *For more details, please refer to the PDF document or feel free to contact us.
