ChangFu® PAN32: Empowering the Glass Fiber Industry, An Efficient Coupling Agent with Excellent Wetting and Film-Forming Effects.

In the expanding field of materials science, ChangFu^® PAN32 (Polyamide Silane) from ChangFu Chemical is quietly accelerating the pace of development in the fiberglass industry. As a silane coupling agent containing polyamide functional groups, ChangFu^® PAN32 is widely suitable for key industrial applications such as coatings, composites, and inorganic fillers. It plays an especially critical role in the fiberglass sector, serving as a key functional additive that combines efficient coupling performance with excellent adhesion promotion.

1. Core Mechanism: Building the "Fiberglass-Resin" Interfacial Bridge

Leveraging its unique bifunctional structure, ChangFu^® PAN32 establishes a stable and robust connection between fiberglass and resin:

n  Hydrolytic Activation: During fiberglass sizing or surface treatment, it hydrolyzes upon contact with water to generate reactive silanol groups.

n  Fiberglass Surface Bonding: Forms stable covalent bonds through condensation reactions, firmly anchoring the silane molecules to the fiberglass surface and creating a uniform organic transition layer.

n  Resin Interface Bonding: Compatible with thermosetting resins such as phenol, melamine, and epoxy that react with amino groups.

2. Key Component in Fiberglass Sizing

In the fiberglass drawing process, polyamide functional silane acts as a crucial coupling agent in the sizing formulation, delivering multiple benefits:

n  Protects Fiberglass Filaments: The organic film formed on the surface reduces friction damage during drawing, lowers filament breakage rates, and enhances anti-static properties.

n  Improves Strand Integrity: Helps bundle multiple fine filaments tightly together, facilitating subsequent weaving or chopping processes.

n  Pre-builds Intern bonding Sites: Introduces reactive groups onto the fiberglass surface in advance, preventing "interfacial gaps" during subsequent compounding with resin and simplifying composite molding processes.

3. Enhancing Performance in Fiberglass Reinforced Plastics (FRP)

      ChangFu^® PAN32 effectively addresses key challenges in conventional FRP materials:

n  Thermoset FRP Applications: Used in wind turbine blades, fiberglass reinforced insulating parts, etc., it enhances the material's fatigue resistance and resistance to heat and humidity by strengthening the chemical crosslinking at the fiberglass-resin interface.

n  Thermoplastic FRP Applications: In automotive components, its polyamide long chains exhibit excellent compatibility with PA resins, effectively reducing "fiber bloom" issues while improving impact strength and tensile strength.

In the fiberglass industry's continuous pursuit of excellent performance and technological innovation, ChangFu^® PAN32, with its unique molecular structure and powerful mechanism of action, demonstrates irreplaceable value in key links such as fiberglass sizing agents and fiberglass-reinforced composite materials.
