LR-1220 Polyaspartic Polyurea Resin to replace NH1220 168253-59-6

PROFILE

LR-1220 is a solvent-free resin with a bis-secondary amine structure, capable of binding with polyisocyanates.

PROPERTY

1. Features high solids content and low viscosity, enabling the formulation of environmentally friendly coatings with high solid content and low viscosity (up to 100% solids during application).
2. Exhibits high reactivity, achieving surface dryness within 2 minutes when cured with HDI trimer, significantly improving production efficiency.
3. Delivers coatings with excellent film build, leveling properties, and high gloss.
4. The film demonstrates outstanding weatherability, low-temperature flexibility, water resistance, solvent resistance, acid/alkali resistance, and salt spray resistance.
5. Offers high hardness (up to 2H) and exceptional abrasion resistance (wear loss ≤ 20 mg at 500r/750g load).
6. Provides excellent adhesion to plastics (e.g., ABS, PC, PVC) and various metallic substrates.
7. Compatible with most hydroxyl-acrylic resins and cellulose acetate butyrate (CAB).
8. Versatile formulation options:
9. When combined with flexible curing agents, produces elastomeric materials with superior mechanical properties (elongation at break: 400%; tensile strength: 25 MPa).
10. When blended with rigid curing agents or HDI trimer/dimer, forms rigid coatings with hardness up to 2H.
11. Suitable for use as a chain extender and primary resin in the R-component of Spray Polyurea Elastomers (SPUA).

1. High-End Coatings: Formulation of automotive paints and premium wood finishes; enhances film build, gloss, hardness, and through-dry time.
2. Protective Topcoats: Suitable for heavy-duty and light corrosion protection systems, including steel structures and petroleum pipelines.
3. Specialty Coatings: Used in foam landscaping products and concrete waterproofing materials.
4. Wind Turbine Blades: Applicable for gel coats, putties, and topcoats.
5. Polyurea/Polyurethane Formulations: Can be used alone or blended with hydroxyl-functional acrylics to react with aliphatic isocyanates for high-solids clear coats; also compatible with amine -functional resins (LR1520, LR1420) to adjust pot life and drying time in high-solids polyurea topcoats.

200KG/drum, 1000KG/drum.

We serve industries such as Polyaspartic coating, cutting fluids, mining support fluids, household care and institutional cleaning, industrial cleaning, pulp processing.

Even if your products do not fall within these industries, you can still contact us. We have our own R&D team and can provide you with customized solutions based on your product needs.

What logistics options do you offer?

We offer both sea and land transportation.

What payment methods do you support?

We support multiple payment methods, T/T.

What is the lead time for bulk production?

Once product samples are confirmed, bulk production typically takes 3-6 weeks to complete and deliver.

Can you assist us with customizing products?

We are more than willing to customize products for you. Our extensive technical team can tailor products to your specific requirements, and adjustments can be made during the sample production phase to meet your needs.

Can I get samples for testing purposes? How are samples shipped?

If you require samples, we can send them to you, but there will be a sample fee involved. If we proceed with further cooperation, we can offset the sample fee against a portion of the bulk order costs to provide you with free samples.

Can I have my logo on the packaging?

Yes, we offer OEM services, but you would need to provide us with your packaging and logo design.
