Sea Field International – Advanced Composite Solutions
Sea Field International Corp., Ltd. is dedicated to delivering precise, efficient, and fully customizable surface treatment formulations for composite materials worldwide. Our product range includes coupling agents, sizing agents, and color agents (paste) for carbon fiber and glass fiber, as well as finishing agents and color agents (paste) for woven fabrics.
Key Advantages:
Custom-Made Development – Customized coupling agents and color agents (paste) designed for both thermoset and thermoplastic resin systems, meeting the specific needs of composite applications.
Performance Enhancement – Our products serve as excellent bonding interface and functional surface coat on fibers, for which improves composite parts manufacturing yield and mechanical strength, compatible with EPOXY, PC, PU, PA, VE, PEEK resin systems, and more upon request.
Process Optimization – Finishing agents, such as fabric setting agent, significantly enhance fabric weave pattern stability, reducing deformation during transport, cutting, and handling, thereby lowering overall manufacturing costs, bringing value-added functions for users.
Color Excellence – High color saturation and superior color fastness, enabling the creation of performance-driven, highly distinctive products.
Through strong partnerships across the value chain, we have built an integrated one-stop supply chain service, delivering complete solutions from material treatment to finished parts.
With our surface treatment agents, colored carbon fiber and glass fiber fabrics offer outstanding resin adhesion, high-temperature resistance (150°C–220°C), anti-yellowing, and UV resistance — suitable for both thermoset and thermoplastic processes — enabling clients to achieve products with both exceptional aesthetics and mechanical performance.
Our Functional Surface Treatments for Composites
We specialize in R&D and sales of advanced surface treatment agents for carbon fiber and glass fiber, offering two main categories:
Colorless Surface Treatments
Our functional surface treatments includes both stardard and cutom-designed products. The fiber sizing product line are designed to enhance fiber-resin bonding and to improve composite parts strength and durability; the finish-oil product line for caron fiber precursor offers low ash content and eco-friendly performance at high temperature process.
Improves fiber abrasion resistance and reduces fuzzing
Highly compatible with multiple resin systems (Epoxy, PC, PA, TPU, PEEK, etc.)
Provides fabric stabilization and superior tension control
High-temperature resistant, low yellowing, suitable for plating adhesion enhancement
Colored Surface Treatments
Fully customized color formulations with functional finishing properties.
Suitable for carbon and glass fibers and fabrics
Exceptional color fastness and saturation
High-temperature resistance and process stability
Anti-UV function avaible upon request
With rigorous quality control and continuous innovation, Sea Field International Corp., Ltd. delivers composite solutions that empower our clients to stand out in competitive global markets.
