Alcohol-soluble polyamide resins are widely used in inks, hot melt adhesives, etc.
Polyamide resin is a chemical raw material with excellent performance and wide application. According to its properties, it can be divided into two categories: non-reactive or neutral polyamide and reactive polyamide. Neutral polyamide.
1. Product performance:
Polyamide resin is a chemical raw material with excellent performance and wide application. According to its properties, it can be divided into two categories: non-reactive or neutral polyamide and reactive polyamide. Neutral polyamide.
| Color (50% resin in 95% ethanol) | ≤5 |
| Acid value (mgKOH/g) | ≤6 |
| Amine value (mgKOH/g) | ≤6 |
| viscosity cp | 150-250 |
| Softening point (ring and ball method) °C | 95-110 |
| Note: The above data is for reference only, the actual experiment shall prevail | |
2. Product function:
Widely used in ink, hot melt adhesive.
1）The heat-sealing polyamide binder is used for strong adhesion because of its resistance to dry cleaning, strong detergents, bleaching agents, and high temperature washing conditions in laundry rooms and households, and it has high adhesion strength to fabrics and is easy to use. The necessary adhesion and excellent moisture resistance are used for heat-shrinkable cable jackets.
2） Neutral polyamides are mainly used in the production of inks, heat-sealing adhesives and coatings, reactive polyamides are used in epoxy resin curing agents, and in thermosetting surface coatings, adhesives, lining materials and canning, Molded resin.
3） Neutral dimer acid polyamide resin has good adhesion on polyethylene and other substrates, and is especially suitable for printing on plastic films such as polyethylene surface packaging film and metal foil composite laminate film.
4） The ink prepared with neutral polyamide resin has gloss, good adhesion, excellent alcohol dilution, low gelling, quick drying and low odor.
Other uses of neutral polyamine resins include the preparation of thixotropic coatings, domestic water-based adhesives, fabric antistatic agents, transparent candles and detergents.
5） The reactive polyamide resin is further reacted and used as a curing agent for epoxy resins, resulting in extensive cross-linking into thermosetting resins. When used as a curing agent, it has the advantages of high flexibility of matching, can be cured at room temperature, and is soft and not brittle, which can make epoxy resin have good adhesion, flexibility, toughness, chemical resistance, and moisture resistance. and surface finish.
6） The use of dimer acid-based acid amine resin-epoxy resin is adhesive, surface coating, potting and molding resin. The adhesive has good wetting performance, high bonding strength, good internal plasticity, and can withstand greater impact force than epoxy resins cured with amines. This kind of adhesive can be used as metal side seam adhesive, plastic and automobile body welding agent and caulking material, and can also be used as metal-metal bonding structural adhesive.
7） Dimer acid-based polyamide-cured epoxy resin has excellent properties such as flexibility, chemical resistance, salt corrosion resistance, impact resistance and high gloss, and is widely used as surface coating.
3. Product packaging:
25KG/bag.
