Por que escolher tinta para PP (polipropileno)?
NúcleoVantagens
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.

ApplicationProcess
Limpeza do substrato
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.
Aplicação do primer
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.
Aplicação da camada final
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.
Inspeção e embalagem
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。Macio livre de poeira Embalagem enviado com lote Testing报告。
