AI Overview
Curing Agent T105 is a
-hydroxyalkylamide (HAA) used in outdoor polyester powder coatings, offering low toxicity and good weather durability. It is generally formulated with carboxylic polyester resins (acid value 25–45 mg KOH/g), with curing typically occurring at 180°C/15min. Key additives include degassing agents like Benzoin (to prevent pinholing) and flow/leveling agents like GLP588.
Key Additives and Formulation Components for T105
- Degassing Agents: Benzoin is essential to prevent pinholing caused by water released during the HAA-polyester crosslinking reaction.
- Leveling/Flow Agents: Agents such as GLP588 or similar acrylic leveling agents (e.g., BLC701) are recommended to improve surface smoothness.
- Matting Agents: To create low-gloss finishes in HAA systems, matting agents like XG665 or VH710 are used.
- Catalysts/Accelerators: While T105 is a curing agent, specialized accelerators may be added to further reduce curing time or temperature.
- Pigments/Fillers: Common fillers like Barium Sulfate () are often used in the formulation.
Recommended Usage
- Dosage: Generally 3–8% based on the resin weight, depending on the polyester acid value (e.g., 3.3wt% for specific high-gloss formulations, 7–8% for typical applications).
- Compatibility: Suitable for use with carboxylic polyester resins, such as those with an acid value range of 25-45 mg KOH/g.
Note: T105M is a variant often supplied by Ningbo South-sea Chemical, designed for similar applications in outdoor powder coatings.

What type of curing agent is used with an epoxy?
Aliphatic amine (Three Bond 2103) is curing agent for epoxy resin ant able to cure at room temperature. The cured resin has excellent properties, and its heat resistance is 100°C. Aromatic amine has been developed to achieve greater heat resistance and chemical resistance than those of aliphatic amine.

Is a curing agent an adhesive?
A curing agent is defined as a substance that enables primary adhesive materials to form netlike or three-dimensional structures, thereby increasing the cohesive strength of the adhesive layer. Common examples of curing agents include amines, acid anhydrides, macromolecules, and sulfurs.

Is hardener a curing agent?
A hardener—also known as a curing agent or crosslinker—is added to adhesives or coatings to improve their overall performance. When mixed with the base adhesive, the hardener triggers a chemical reaction (crosslinking) that transforms the material into a tougher, more durable structure.
