2. Product Description

1,3-BDX is a modified amine epoxy curing agent derived from MXDA. It is designed for epoxy curing systems that require good color stability, moderate viscosity, fast curing performance, wet surface adhesion and excellent chemical resistance.

In epoxy resin systems, 1,3-BDX can be used directly as a curing agent or combined with other amine curing agents to improve processability, adjust curing speed and enhance corrosion resistance and water resistance of cured products. It is suitable for floor coatings, industrial protective coatings and adhesive systems requiring adhesion and durability.

 

3. Structure Features and Key Advantages

3.1 Structure and Reactivity

1,3-BDX is based on an MXDA-derived modified amine system. It retains amine reactivity toward epoxy resin while improving compatibility and application stability. Compared with conventional low-molecular amine curing agents, it offers a balanced profile of processability, wet surface adhesion, later-stage curing speed and resistance properties.

3.2 Key Advantages

· Good color stability for appearance-sensitive coatings and adhesives.

· Moderate viscosity for easier mixing with epoxy resin and formulation adjustment.

· Fast curing performance to improve application efficiency and shorten curing time.

· Good wet surface adhesion for demanding application conditions.

· Excellent corrosion and water resistance for long-term durability.

· Flexible formulation use: suitable for direct use or blending with other curing agents as an accelerator or performance modifier.
