Teflon® Coating / Spray Coating

Do your parts present a unique coating challenge?

With over 60 years of experience and technical innovation, Thermech will transform your challenge into a success.  We routinely apply extreme-service Teflon® coatings with unsurpassed quality, even to hard-to-coat parts.

Our coating selection expertise and application methods are second to none.  We have achieved unheard of combinations of coating thickness, chemical resistance, temperature resistance, color, gloss or matte finish, abrasion resistance, hydrolytic stability, adhesion, electrical properties and custom masking.  And we can coat parts that others can’t, such as the ID of extremely narrow medical hypotubes.  All at reasonable price points and fast turnaround times.

Even when we use the same coating materials as other coating applicators, we apply the coatings using innovative, improved methods to achieve superior results.  Some of the many ways that we improve upon standard coating practices:

1. •Consistent, superior surface preparation
   

2. •Additional processing steps between coats to improve appearance and intercoat adhesion
   

3. •Highly tailored thickness for each coat in multi-coat systems
   

4. •Customized numbers of primer-, mid- and topcoats according to the application requirements
   

5. •Custom drying and curing cycles
   

1. 1.temperature ramp
   

2. 2.time at maximum temperature
   

3. 3.cooling speed
   

4. •Viscosity adjustments based on decades of experience
   

5. •Proprietary coating additives for enhanced properties
   

6. •Application-specific coating ingredient ratios
   

7. •Custom-made masking for superior precision and to improve masking speed to lower costs
   

We use a full range of coating materials and techniques to deliver the best solution for your project.  We can handle even the toughest-to-coat surfaces or parts that are extremely small or very large.

We have developed techniques and processes that allow us to serve even the most quality-oriented industries such as aerospace and medical devices.

If none of our existing coating materials meets your requirements, we will compose a unique product for you as we have done for so many other customers.  Our proprietary TECfluorcote fluoropolymer coatings and TECthermcote non-fluoropolymer coatings are unique solutions that complement standard industrial coatings.
