Applications

 

Our  Functional Additvess is suitable for a wide range of  paints and coating  with excellent perfomrance

 

  • #
    Plastic Coating
     
    Low-energy plastic surfaces (PP, PE, ABS) challenge adhesion and leveling. Our additives overcome these hurdles:​
    Adhesion Promoters: Bond coatings to automotive plastic trims or electronics casings, preventing peeling during temperature cycles.​
    Leveling Agents: Ensure uniform coverage on curved plastic parts (e.g., toy components), eliminating edge buildup.​
    Anti-foaming Agents: Suppress foam in high-speed sprayed plastic coatings, avoiding defects in consumer goods like appliance panels
  • #
    Heavy Coating 
    Heavy corrosion protection relies on barrier integrity and adhesion. Our additives reinforce these critical properties:
    Wetting & Dispersing Agents: Disperse zinc particles evenly in galvanizing primers, ensuring consistent sacrificial protection for marine or oil rig equipment.​
    Rheology Modifiers: Control viscosity in pipe coatings, enabling thick films that resist sagging on vertical surfaces while maintaining adhesion.​
    Adhesion Promoters: Enhance bonding to rust-prone metals (e.g., iron), ensuring the anti-corrosive layer stays intact under salt spray or chemical exposure.
  • #
    Wood Coatings
    Wood surfaces demand smoothness, depth, and resistance to wear. Our additives tailor formulations for furniture, flooring, and cabinetry:​
    Leveling Agents: Eliminate brush marks in hand-applied stains, ensuring a glass-like finish on oak or maple.​
    Anti-foaming Agents: Prevent micro-foam in waterborne wood sealers, avoiding tiny bubbles that mar the wood grain.​
    Rheology Modifiers: Thicken floor coatings to resist sagging on vertical edges (e.g., chair legs) while maintaining sprayability.​
    Wetting & Dispersing Agents: Ensure uniform color in tinted wood stains, preventing streaks in porous woods like pine.
  • #
    Aluminum Alloy Coatings
    Industrial substrates (metals, plastics, composites) require durability and processability. Our additives optimize performance in factories and workshops:​
    Rheology Modifiers: Stabilize heavy-duty machinery coatings, preventing pigment settling during storage and ensuring even film build on large parts.​
    Wetting & Dispersing Agents: Improve corrosion-inhibitor dispersion in metal primers, enhancing rust protection for steel structures.​
    Adhesion Promoters: Boost bonding in plastic industrial parts (e.g., polypropylene bins), ensuring coatings resist impact and chemical exposure.

 

 

Benefits

 

Multi-Substrate Compatibility: Our additives work seamlessly with solvent-based, waterborne, and high-solids coatings, adapting to diverse resins like acrylics, polyurethanes, and alkyds.​ Dosage Efficiency: Low usage rates (0.1–5% by weight) deliver maximum impact, making them cost-effective enhancers for large-scale production.​ Performance Synergy: They don’t just solve single issues—e.g., a wetting agent improves pigment dispersion and enhances gloss, while a rheology modifier prevents sagging and improves storage stability.​ Formulation Flexibility: Easy to integrate into existing workflows without disrupting cure times, viscosity, or drying properties, simplifying adoption.
