Company Profile
Suzhou Xushuguan Chemical Additives Co., Ltd. was founded in 1979, formerly known as Suzhou Xushuguan Chemical Additives Factory. Specializing in metal surface rust inhibitors and anti-rust oils, we boast nearly 50 years of industrial experience. The Company launched dinonylnaphthalene sulfonate product line in 1987 and is one of the major manufacturers of dinonylnaphthalene sulfonate rust inhibitors. We maintain a stable customer base in the niche market, with products sold to Asia, North America, the EU and South America, and recognized by numerous customers. We uphold the tenet: "Sound testing conditions and management practices form a solid guarantee for corporate reputation."
Over the past decades, our company has continuously improved the quality of dinonylnaphthalene sulfonate products, investing sufficient technical resources and capital in the iteration and upgrading of physicochemical indicators including purity, color and demulsification resistance. Our product portfolio has expanded from the initial barium salt to calcium, zinc, magnesium and ammonium salts, enabling us to deliver multi-dimensional anti-rust solutions for customers and build differentiated product advantages.
In the late 1990s, the EU tightened relevant restrictions on the use of barium salts. To comply with EU regulations on heavy metal control, our company initiated the R&D of eco-friendly products such as calcium salts and zinc salts. We keep launching environmentally friendly rust inhibitors to meet customers’ evolving application needs.
Meanwhile, adhering to the philosophy of continuous innovation, we keep optimizing the production processes of traditional sulfonate rust inhibitors such as barium alkylbenzene sulfonate and calcium alkylbenzene sulfonate. We have developed high-barium-content barium alkylbenzene sulfonate and high-base-number calcium alkylbenzene sulfonate, providing customized technical solutions for premium lubricant manufacturers.
Beyond the lubricant market, our mature sulfonation technology has been extended to the acid catalyst sector. We provide catalyst solutions better suited to working conditions for customers in the coatings and rubber industries. InCat is a professional acid catalyst platform that optimizes curing temperature and curing efficiency, and effectively improves comprehensive coating performance including hardness, flexibility, chemical resistance and adhesion. The InCat product series covers blocked and unblocked dinonylnaphthalene monosulfonic acid, dinonylnaphthalene disulfonic acid, dodecylbenzenesulfonic acid and p-toluenesulfonic acid.
Our business philosophy is "Taking customer demand as the guidance for product manufacturing and sales". We closely integrate production and service, and are committed to building stable and sound customer partnerships. We forge ahead together, pursue common development and achieve win-win cooperation.
