I. What is a polyaspartic polyurea?
Polyaspartic Polyurea is the third generation material,polyasparticResin reacts with the aliphatic isocyanate hardener. Compared to the traditional aromatics of polyurea, polyaspartic polyurea, which uses aliphatic structures, weather resistance, non-yellow, non-polluting, etc.
The core material for polyaspartic is polyaspartic, which is combined with a reaction synthesis by Michael, with stable and aminomethylate keys in the molecular structure, giving them excellent physical and chemical resistance.
Core performance characteristics
2.1 quick fixation
The time of the polyaspartic polyurea touch-dry ≤30 min, hard-dry time ≤4 Hours will significantly shorten the construction cycle and improve the efficiency of the work. Compared to traditional epoxy paints, 24 More than an hour of curing, more efficient construction of polyaspartic polyurea 3-5 Double.
2.2 Excellence
aliphatic structures give UV resistance to winterization and use 10 outdoors for non-yellowing and non-pollution. QUV Accelerating Aging Test 5000 hours after ≥80%, the protection rate is much better than aromatic polyurea and epoxy paint.
2.3 High adhesion
Test:GB/T 5210-2006 / ISO 4624
Test results:≥10MPa (steel base), which is destroyed by internal concentrations. The excellent adhesion ensures that the coatings remain intact for a long time.
2.4 resistant to chemical corrosion
- Acid resistance: 10% H₂SO₄、 10% HCl soak 90 There's no anomaly.
- Alkali resistance: no abnormalities after 90 days of immersion in 10% NaOH or saturated Ca(OH)₂
- Salt resistance: 10% NaCl impregnated 90 day-by-day
- Water resistant: 365 Day impregnated
2.5 Mechanical Performance
- tensile strength ：≥20MPa
- elongation at break ：≥200%
- Hardness:Shore D 50-60
- Retardability:≤30mg (1000 rotation, H18 wheel, 1000g load)
2.6 Environmental performance
100% solids content, solvent-free, VOC< 50g/L, meets the requirements of GB 38508-2020 and REACH regulations. The construction process was unsavoury and environmentally friendly and applied to indoor and enclosed space construction.
III. Typical application scenarios
3.1 Waterproof Project
Polyaspartic polyureaWaterproof coatingsIt applies to waterproof scenes such as the roof, basement, toilet, pool, etc. Excellent waterproofness and durability, with a useful life of more than 20.
3.2 corrosion Project
Polyaspartic polyureaAnti-corrosion coatingsIt applies to harsh corrosive environments such as petrochemical storage tanks, marine platforms, trans-sea bridges and sewage treatment tanks. Sat-spray performance 6000 The service life of the equipment was significantly extended over the hours.
3.3 flooring Project
Polyaspartic polyureaflooringFor new energy plants, food and medicine workshops, commercial parking lots etc. Quick fixation, high resistance to grinding, easy to clean, meeting the GMP cleanness requirements.
3.4 Decoration Project
Polyaspartic polyurea Decorative Paints are colorful, weather resistance is excellent and applies to exterior wall decorations, landscape facilities, art installations, etc. Long-term outdoor use does not fade, does not pollinate.
IV. Comparison with traditional materials
Concluding remarks
polyaspartic polyurea, a third generation of poleurea materials, has become the preferred material in the fields of waterproofness, protection, decorative and decorative, with the core advantages of fast curing, tolerance, high adhesion and resistance to chemical corrosion.
