With direct manufacturing at our Maoming production base, we support industrial customers with stable commercial supply, batch quality management, technical documentation, samples, and flexible packaging options. Our integrated business model helps customers move efficiently from product evaluation to regular purchasing.
Huajinda DDSA Grades & Typical Specifications
Huajinda supplies two DDSA grades, CA-I-02 and CA-I-05. Both have a DDSA content specification of ≥98.0%, while differences in the olefin structure result in different branching distributions and viscosity profiles.
A general-purpose DDSA grade with a viscosity specification of 40–60 mm²/s and free olefin controlled at ≤1.5%. Suitable for evaluation in epoxy curing, metal protection, and other industrial formulations.
A DDSA grade based on a different olefin structure and branching profile, with a viscosity specification of 70–90 mm²/s and tighter free-olefin control of ≤1.0%.

DDSA Applications in Epoxy and Metal Protection Systems
The combination of a reactive anhydride group and a hydrophobic alkenyl chain allows DDSA to be used in both epoxy curing and selected oil-based industrial formulations.
Used as a liquid anhydride curing agent in epoxy casting, sealing, and encapsulation formulations.
Used in epoxy insulation and low-temperature casting systems.
Used as a DDSA lubricant additive in anhydrous lubricants, turbine oils, and hydraulic oils.
Used in corrosion-control, metal cleaning, and rust-preventive formulations.
Reactive Anhydride Structure for Versatile Formulation Use
DDSA combines a reactive anhydride group with a hydrophobic alkenyl chain, giving it value in both epoxy curing and oil-based industrial systems. It can participate directly in epoxy curing reactions and also serve as a reactive intermediate for selected ester- and amide-based derivatives used in lubricant and corrosion-control applications.
Huajinda: Production and Service Support for Global Customers
Backed by three production bases and an experienced international business team, Huajinda supports overseas customers from initial product communication through regular commercial supply. We currently work with more than 200 customers across markets including East Asia, Southeast Asia, Europe, and the Americas. Direct coordination between production and international sales helps us respond efficiently to requirements involving specifications, export documents, shipment schedules, and repeat orders.
- Quality Certification
Both CA-I-02 and CA-I-05 have a DDSA content specification of ≥98.0%, but they are based on different olefin structures. The difference in olefin structure results in different branching distributions and is reflected in their viscosity profiles.
DDSA is mainly used as a liquid anhydride curing agent for epoxy systems and as a functional or reactive raw material in selected lubricant, metal cleaning, corrosion-control, and rust-preventive formulations.It may also be further reacted with alcohols or amines to prepare selected ester- or amide-based derivatives.
Yes. Huajinda can provide samples, TDS, MSDS, product specifications, and batch COA for evaluation. When requesting a sample, customers may share the intended application, current formulation route, required quantity, and destination so that the appropriate grade, packaging, and shipment arrangement can be discussed.
The standard packaging is a 950 kg IBC tote, while other arrangements may be discussed according to order requirements. DDSA should be stored in a sealed container in a cool, dry place away from direct sunlight. Opened containers should be resealed promptly. The stated shelf life is 24 months under the recommended storage conditions.
