Hot Melt Adhesive Polyamide Resin Granules High Bonding Strength For Packaging & Textile
Alcohol-Soluble Polyamides
Solubility: Dissolve in alcohol solvents, often due to introduced hydrophilic groups (e.g., -OH or -NH2).
Applications:
Coatings: Used in alcohol-based inks, adhesives, or protective coatings for plastics/metals.
Packaging: Food-grade coatings due to low toxicity.
Electronics: Temporary protective films in PCB manufacturing.
Benzene-Soluble Polyamides
Solubility: Dissolve in non-polar aromatic solvents (e.g., benzene), typically achieved by incorporating flexible aliphatic chains or aromatic monomers.
Applications:
Adhesives: High-performance bonding agents for heat-resistant materials.
Films/Textiles: Water-resistant coatings or fiber processing.
Industrial: Compatibilizers in polymer blends.
Q1: What is your polyamide resin mainly used for?
A: Our polyamide resins are versatile and serve as excellent curing agents/hardeners for epoxy resins and as binders in various applications. Key industries include:
Coatings: High-performance protective coatings for marine, industrial, and automotive applications.
Adhesives: Especially in high-strength structural adhesives and flexible hot-melt adhesives.
Inks: As binders for printing inks, offering excellent adhesion to flexible substrates like plastic films.
Construction: Used in flooring compounds and civil engineering for its toughness and chemical resistance.
Q2: Is your polyamide resin a solid or a liquid? What is the physical form?
A: We supply polyamide resin in different forms to suit various application methods:
Solid Form: Available as granules, pellets, or powder. This form is typically used in hot-melt adhesives and powder coatings.
Liquid Form: Available in solvent-based or water-based (emulsion) versions. Liquid resins are primarily used as curing agents for liquid epoxy systems in coatings and adhesives.
Q3: What are the key advantages of using your polyamide resin over other hardeners?
A: Our polyamide resins offer several distinct benefits:
Excellent Flexibility: Imparts outstanding toughness and impact resistance to the cured epoxy film.
Strong Adhesion: Bonds well to a wide variety of substrates, including concrete, metals, plastics, and wood.
Good Chemical Resistance: Particularly resistant to water, chemicals, and corrosion, making it ideal for harsh environments.
Low Toxicity & User-Friendly: Compared to other amine hardeners, polyamides have lower vapor pressure and are less irritating to the skin.
Good Surface Wetting: Provides excellent flow and leveling on surfaces.
Q4: What is the typical mix ratio with epoxy resin?
A: The mix ratio is critical and varies significantly depending on the specific grade of our polyamide resin and the epoxy resin you are using. It is typically calculated based on the amine value of our product and the epoxy equivalent weight (EEW) of your epoxy resin. The standard ratio often ranges from 1:1 to 2:1 (epoxy : hardener) by weight. Please always refer to the Technical Data Sheet (TDS) for the exact mixing ratio for each product.
Q5: What is the pot life of the mixture after combining with epoxy?
A: Pot life depends on the specific product grade, mix ratio, and ambient temperature. A typical pot life for polyamide-cured epoxy systems can range from 30 minutes to several hours at 25°C (77°F). Higher temperatures will significantly shorten the pot life. Please check the TDS for precise data.
Q6: Do you offer technical support and documentation?
A: Absolutely. We provide comprehensive technical support for our customers. For each product, we can supply:
Technical Data Sheet (TDS)
Material Safety Data Sheet (MSDS/SDS)
Product Specifications Sheet
You can request these documents directly from our sales team.
Q7: What is your minimum order quantity (MOQ)?
A: Our standard MOQ is 500kg for trial orders. However, we are flexible and can accommodate smaller quantities for new customers who wish to test our product. Please contact us to discuss your specific needs.
Q8: How is the product packaged and shipped?
A: We use secure, industry-standard packaging to ensure product integrity during transit:
Solid Forms: Packed in 25 kg multi-layer paper bags or 500/1000 kg palletized bags.
Liquid Forms: Packed in 200 kg iron drums or 1000 kg IBC totes.
We have extensive experience in shipping chemicals globally by sea, air, or land and can handle all necessary documentation.
Q9: Are you a manufacturer or a trading company?
A: We are a professional manufacturer of polyamide resins with our own factory and advanced production facilities. This allows us to control quality strictly, offer competitive prices, and provide reliable OEM/ODM services.
Q10: Can you produce custom formulations according to our requirements?
A: Yes, we have a strong R&D department and offer OEM/ODM services. We can adjust properties like viscosity, amine value, curing speed, and compatibility to meet your specific application needs. Contact us with your requirements, and we will develop a solution for you.
