Stainless steel fibers can be bound or coated with various polymers to enhance adhesion and functionality in composite materials. Some commonly used polymers include:
- Polypropylene (PP): Used in hybrid yarns, PP provides customizable adhesion with stainless steel fibers for impact-resistant composites.
- Polylactic Acid (PLA): Often used in 3D printing, PLA-coated stainless steel fibers improve mechanical strength and durability.
- Epoxy Resins: Provide strong adhesion and are commonly used in fiber-reinforced composites for structural applications.
- VAE polymers, for high adhesion, durable, flexible, bonds. VAE is often compatible with other polymers and resins, to increase tack, flexibility or adhesion.
- VC polymers especially resins with function groups, offer superior adhesion with unrivalled flexibility
Vinyl polymer coatings
Vinyl polymers, such as polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC), are unique for steel coatings because they provide excellent corrosion resistance and moisture barrier properties. PVDC emulsions, for example, are used in anti-corrosion coatings for metal, offering strong adhesion and durability. Additionally, vinyl polymers can be fine-tuned for flexibility, abrasion resistance, and flame retardance, making them versatile for industrial applications.
VAE Polymers for stainless steel coatings
Vinyl Acetate-Ethylene (VAE) dispersions are interesting for stainless steel coatings because they offer strong adhesion, flexibility, and low VOC emissions. Their thermoplastic nature allows for easy recycling, making them a sustainable choice for coatings. Additionally, VAE dispersions provide good film-forming properties at low temperatures, eliminating the need for extra coalescing agents. Some formulations, enhance wet tack and shear strength, making them ideal for metal adhesion applications
