Automated Powder & Wet Spray Lines
All of Teknicote's automated lines are capable of handling high volume coating applications of both small and large parts with efficiency while maintaining the highest level of quality and repeatability.
Teknicote's ability to maintain short lead times is made possible by using multiple sets of part specific custom tooling. In almost all cases at Teknicote two sets of tooling are required rather than three or more which saves our customers money. This is made possible by the short cycle time of our fluidized bed sand stripping process which allows for uninterrupted operation of all of our automated coating equipment.
There are many powder options available to fulfill their own unique criteria. No matter the job, big or small, highly functional or aesthetic, Teknicote will help you find the right fit for your needs at the best price.
Types of Powders
Not all powders are created equal. Some chemistries perform better than others against certain environmental criteria. It is important to know how the product will ultimately be used before selecting the type of powder for application.
Epoxy coatings provide a smooth, uniform appearance. They also offer excellent adhesion and exhibit a strong resistance to chemicals and corrosion. However, epoxies can only withstand minimal UV exposure. Over-exposure to UV rays can lead to loss of gloss as well as chalking of the finished product. As a result, epoxy powders are generally used for interior-based products.
Polyester powders offer strong adhesion properties and excellent gloss retention when exposed to UV elements. Due to their strong weathering characteristics and lower chemical resistance, polyester powders are typically found on fencing, outdoor decorative items as well as lawn and garden furniture.
Nylon powders are generally used as a protective coating. They offer strong resistance to a wide range of solvents and oils, as well as damage caused by impact and abrasion. In most cases, a primer is used in the coating process to help achieve a high level of performance.
Polyurethane powders are generally used for both decorative and functional products that have exterior exposure. Polyurethane's have very strong weatherability characteristics. They offer excellent anti-corrosion performance and are resistant to humidity and a range of chemicals and oils.
Hybrid powders are blends of epoxy and polyester resins. As such, they offer excellent mechanical properties and very good chemical and corrosion resistance. While these coatings provide excellent flexibility and smoothness, they are generally not recommended in applications where weather resistance is critical. Hybrids are typically used for indoor applications.
Metallic coatings are offered in a variety of chemistries from epoxies and polyesters, to hybrids. These coatings have metallic particles added to the chemistry of the powder for aesthetic purposes. Their highly attractive visual attributes combined with their strength and durability make them an ideal choice.
Anti Microbial powder coat
These coatings use silver ion technology to fight bacteria and mold. Great for use in high traffic areas, medical devices, food processing equipment, railings and play grounds.
