Polymer finishing

Polymer finishing:

Acrylic Spray Paints:

Advantages Disadvantages
  • Provide a smooth, glossy finish that enhances the appearance of polymers
  • Available in a variety of colours, allowing for customisation
  • Quick-drying and easy to apply, making it suitable for a range of applications
  • Can scratch or chip over time, affecting the finish's durability
  • Requires proper ventilation and safety precautions during application due to fumes

Uses: Customised finishes for products like plastic models, outdoor furniture, signage, and decorative items



Thermoplastic Elastomer:

Advantages Disadvantages
  • Provides flexibility and elasticity, making it ideal for products like seals and gaskets
  • Can be easily moulded into different shapes and sizes
  • Offers a rubber-like feel and durability, while remaining recyclable
  • Can be expensive compared to other polymers
  • May be prone to degradation from UV light exposure and certain chemicals

Uses: Flexible products such as seals, gaskets, grips, footwear, and medical devices




Pigment Additives in Polymers

Gel Coats (for laminating GRP):

Advantages Disadvantages
  • Provides a high-quality, glossy finish that enhances the appearance of GRP (Glass Reinforced Plastic)
  • Offers protection against water, chemicals, and UV light, prolonging the material’s lifespan
  • Used in applications where aesthetics and durability are important, such as boats and swimming pools
  • Requires careful application to avoid defects such as runs or uneven surfaces
  • Can be challenging to repair if damaged

Uses: Boat hulls, swimming pools, automotive parts, and other GRP products



Smart Pigments (Thermochromic or Phosphorescent):

Advantages Disadvantages
  • Thermochromic Pigments: Change colour in response to temperature, adding interactivity and novelty to products
  • Phosphorescent Pigments: Glow in the dark, making them useful for safety or decorative applications
  • Can create innovative designs in toys, apparel, and safety equipment
  • Thermochromic Pigments: Limited colour change range and may degrade over time with repeated temperature fluctuations
  • Phosphorescent Pigments: Limited glow duration and can lose effectiveness over time
  • Can be more expensive compared to regular pigments

Uses: Toys, clothing, safety signs, novelty products, and packaging with interactive or glow-in-the-dark features
