Scientifically formulated with premium resins and imported pigments and fillers, it offers excellent adhesion, durability, and application performance. 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 PP polypropylene specialty coatings, from formula design and raw material procurement to production and filling. The products are certified to environmental regulations such as ROHS and REACH. We provide free sample testing and on-site guidance services by technical engineers.
Why choose PP (polypropylene) coating?
CoreAdvantages
CPP primer flame-free treatment technology
The CPP (chlorinated polypropylene) adhesion primer, developed for the extremely low surface energy of PP materials, can form physical entanglement and microcrystalline anchoring with PP substrates. It eliminates the traditional flame or plasma pretreatment process, simplifying the production line and reducing equipment investment and energy consumption. After the primer dries, the adhesion reaches 5B grade, allowing topcoat application directly.
Dedicated matching system for PP substrates
The two-layer matching system of PP-specific primer + PP-specific topcoat ensures complete adhesion and durable protection from primer to topcoat. The topcoat offers a rich range of colors (full RAL color system) and adjustable gloss (high gloss/semi-gloss/matte). The coating has excellent flexibility and can follow the thermal expansion and contraction of PP substrates without cracking or peeling.
Weather and yellowing resistance, 10-year quality
Uses aliphatic polyurethane curing agent combined with an efficient UVA+HALS light stabilization system. QUV accelerated aging 500h ΔE<3等同于户外10 years non-yellowing。Suitable ForAutomotive外饰件和户外Furniture等长期暴露在阳光下的PP制品SurfaceCoating Application。
Professional coating technology support services
Kexin has an experienced coatings R&D and applications team that supports the whole process - substrate analysis, coating selection, optimisation of process parameters and on-site application guidance. Our engineers commission the coating parameters on your own production line so that finish quality and output are both optimised.
Eco-compliant green manufacturing system
All products are RoHS/REACH compliant and their VOC content meets national environmental standards. Waterborne and high-solids low-VOC formulations are continuously refined to keep pace with ever stricter environmental requirements. Environmental performance test reports issued by third-party authorities such as SGS and CTI are available on request.
Complete quality control and batch traceability
A quality-control system covering the whole process, from incoming raw materials to finished-goods dispatch. Every batch undergoes rigorous physico-chemical testing and simulated application trials. Batch numbers are traceable end to end, so raw-material sources and production data can be retrieved. Each shipment is released with a batch test report and a product warranty, so customers can use it with confidence.

Frequently AskedFAQ
ApplicationProcess
Substrate cleaning
Thoroughly remove mold release agents and oil stains from plastic substrates using isopropyl alcohol or a specialized cleaner. For PP and PE substrates, flame treatment or plasma pretreatment can be optionally used to enhance surface energy. For ABS and PC substrates, wipe off dust with an antistatic cloth. Ensure the surface is clean and free of residues.
Primer application
Spray one coat of adhesion primer specifically for plastics. Use CPP chlorinated polypropylene primer for PP substrates. Use PA-specific primer for nylon. For ABS and PC, which have good adhesion, primer can be used optionally. Bake the primer at 60°C for 10 minutes, with a pre-bake film thickness of 10-15 μm.
Topcoat application
Apply 2 precise coats of topcoat, with a 60°C flash-off for 5-10 minutes between each coat. For the elastic tactile paint, appropriately thicken the final coat to achieve a full rubber-like feel. Total dry film thickness: 30-50μm. After spraying UV paint, pass through a UV curing machine. Ensure uniform color consistency with no runs or sags.
Curing process
Bake at 60-80°C for 20-30 minutes or air-dry at room temperature for 24 hours for complete curing. UV coatings are instantly cured by exposure to a UV curing machine at 800-1200 mJ/cm². Oven temperature uniformity is ±5°C, with gradual heating to avoid coating defects. For plastic substrates, the baking temperature must be controlled to not exceed the substrate's heat deflection temperature.
Inspection & packaging
After complete curing, use a cross-cut tester to check the adhesion level. Test for gloss/color difference/sweat resistance/cosmetics resistance. Plastic parts require special inspection for solvent attack. QUV yellowing resistance test 500h ΔE.<3。Dust-free soft Packaging shipped with batch test reports。
