Antimicrobial Powders
Today, coatings manufacturers are formulating solutions with silver ionic technology that help to inhibit the growth of microbes and fungi on cured paint films that can lead to unpleasant odors, discoloration and corrosion.
In layman’s terms, silver ions penetrate the membranes of bacteria, bind to essential elements like DNA and disrupt their functions, including multiplying, ultimately helping to deactivate them.
These antimicrobial protected powder coatings are durable, retain their color and are stable even in high temperature and work to guard the substrate from the growth of harmful microbes and bacteria.
Extreme Mar-Resistant Powders
Extreme mar-resistant powders provide exceptional resistance to scratches, scuffs, corrosion and UV exposure.
Common applications include appliances, shelving, fitness equipment, furniture and building products where finish appearance and durability are critical over the product's lifecycle.
Typical applications:
- Appliances
- Shelving systems
- Fitness equipment
- Furniture
- Building products
Anti-Graffiti Powders
Graffiti removal can be costly and time-consuming for municipalities, transit systems and property owners.
Anti-graffiti powder coatings create a non-porous surface that prevents paints, markers and adhesives from bonding strongly to the substrate. This allows graffiti to be removed more quickly and economically, often without harsh chemicals, while helping to preserve appearance and reduce maintenance costs.
Typical applications:
- Transit systems
- Public infrastructure
- Street furniture
- Commercial buildings
- Architectural surfaces
