Water-BasedPolyurethane Coating
KF-WI200 Water-Based PU Coating
KF-WI200 Waterborne Polyurethane Coating is based on waterborne acrylic polyol and waterborne isocyanate. The coating combines excellent outdoor weather resistance (QUV 1500h gloss retention >80%) and low VOC environmental protection characteristics. Widely used in outdoor steel structures/construction machinery/agricultural equipment/commercial vehicles and other industrial coatings requiring outdoor weather-resistant protection.
ProductsOverview
Waterborne polyurethane coating is a high-performance professional coating product developed and produced by KeXin New Material. It is scientifically formulated with high-quality resins and imported pigments and fillers, offering excellent adhesion, durability, and application performance. It is widely used in industrial manufacturing, architectural decoration, automotive and transportation, and other fields.
As a source coating factory, KeXin New Material strictly implements the ISO9001 quality management system for waterborne polyurethane coatings from formula design and raw material procurement to production and filling. The products are certified under ROHS, REACH, and other environmental regulations. Free sample testing and on-site guidance by technical engineers are provided.
Why choose waterborne polyurethane coating?
CoreAdvantages
Waterborne polyurethane — outdoor ultra-weather resistance
Waterborne acrylic polyol + waterborne isocyanate (Hydrophilic HDI) two-component system. After curing, it forms a polyurethane crosslinked network comparable to solvent-based PU coatings. QUV 1500h gloss retention >80%, excellent outdoor weather resistance. The coating does not yellow or chalk, suitable for long-term protection of outdoor steel structures and engineering equipment.
Ultra-low VOC · Complies with the strictest environmental regulations
VOC<100g/LFar BelowGB 30981IndustrialProtective coating限量Standard(<420g/L)。Complies欧盟2010/75/EUIndustrial排放指令和美国CARBEco-Friendly法规。export欧盟和North America market的机械设备coatingsEco compliance。Water-Based清洗减少solvent消耗ReducesVOC总排放。

Frequently AskedQuestions
ApplicationProcess
Surface preparation
Thoroughly degrease and degrease the substrate, clean to remove oxide scale, oil stains, and rust. Sandblast steel to Sa2.5 grade with roughness Rz40-75μm. Acid pickling and passivation or chromate treatment for aluminum. Remove all contaminants to ensure the surface is clean with no residue. Ambient temperature 5-40°C, relative humidity<85%。
Primer / pre-treatment
Select a matching primer or pretreatment based on the substrate and system. Powder coatings can be applied directly to sandblasted substrates without a primer. Water-based paints require a dedicated water-based primer to seal the substrate. Strictly control primer film thickness and drying conditions according to product requirements.
Main-coat application
Powder coatings are applied evenly by electrostatic spraying (corona or tribo). Water-based industrial paints are applied by high-pressure airless spraying or air spraying. Strictly control application parameters such as film thickness/environmental temperature and humidity/flash-off time. Before baking, check that the coating is uniform with no missed areas and no sagging.
Baking Curing
Powder coatings are baked at 180-200°C for 10-20min to fully cure, melt, level, and form a film. Water-based paints are low-temperature baked at 60-80°C or air-dried at room temperature. Oven temperature uniformity ±5°C, gradually increase temperature to avoid pinholes and bubbles. After curing, naturally cool to room temperature.
Inspection & packaging
Test performance indicators such as film thickness/gloss/adhesion/hardness/impact resistance/salt spray resistance. For powder coatings, check coating uniformity and degree of cure (solvent rub method). For water-based paints, check water resistance and weather resistance. After all pass, package and ship in a dust-free manner.
