CORE HM 325; Core chemical ; Hot melt Polyamide for metal

Product Description
CORE HM 325 is a premium-grade polyamide hot melt adhesive specifically engineered for demanding industrial applications. This high molecular weight formulation offers exceptional bonding capabilities for diverse substrates, including PCB components, metals, plastics, leather, and fabric materials. The adhesive demonstrates superior mechanical strength and heat resistance while maintaining optimal flexibility. Its notable solubility in mixed organic solvents, including aliphatic and aromatic hydrocarbons and alcohols, ensures versatile application methods. The extended open time provides excellent workability, making it ideal for precise assembly operations. This professional-grade adhesive delivers reliable performance and durability in critical bonding applications across multiple industries.

Epoxy Adhesives

Nature:

• Two-part system (resin + hardener) or one-part heat-curing.

• Cures chemically (thermosetting).

• Forms very strong, rigid, and chemical-resistant bonds.

Applications:

1. Construction & Civil Engineering

   • Structural bonding (concrete, steel, rebar anchoring)

   • Flooring & coatings (epoxy floor paints, grouts)

2. Electronics

   • Encapsulation & potting (protecting circuits)

   • Semiconductor packaging

3. Automotive & Aerospace

   • Bonding metal, composites, ceramics

   • Structural parts requiring high mechanical strength

4. Marine & Industrial

   • Corrosion protection coatings

   • Heavy-duty machinery assembly

5. Consumer Products

   • DIY bonding (metal, ceramics, plastics, wood)

   • Sports equipment, bicycles, boats

EVA Hot-Melt Adhesives (Ethylene-Vinyl Acetate)

Nature:

• Thermoplastic adhesive, applied in molten form (~120–180 °C).

• Solidifies on cooling, bonds quickly (non-reactive).

• More flexible and faster than epoxy, but lower strength & heat resistance.

Applications:

1. Packaging Industry

   • Carton sealing, case sealing

   • Labeling, bookbinding

2. Textiles & Footwear

   • Shoe sole bonding

   • Lamination of fabrics

3. Woodworking & Furniture

   • Edge banding, profile wrapping, veneering

4. Electronics & Appliances

   • Wire tacking, small component assembly

   • Insulation & tamper-evident seals

5. Automotive Interiors

   • Upholstery, carpet fixing

   • Trim assembly

6. DIY & Craft

   • Hot glue guns for hobby applications

Key Differences (Epoxy vs. EVA Hot Melt)

✅ Summary:

• Epoxy → heavy-duty, structural, high-performance bonding (metal, concrete, composites).

• EVA Hot Melt → fast, flexible, economical bonding (packaging, textiles, crafts).
