Whitford’s New Textile Finishes/Coatings Offer Superior Performance:

• Superior release
• Superior low friction
• Superior resistance to abrasion
• Superior water repellency
• Superior combination of tensile strength and flexibility
• Superior resistance to oils from cooking, chemicals, UV
• Superior overall performance for all types of textiles
  

Whitford has always been a leader in the development of special finishes/coatings. Following is a summary of how we have adapted our technology to this highly specialized market with our textile line of finishes.

Typical substrates range from:

1. Low-temperature materials such as polyester, polyamide, polyurethane, etc.
2. High-temperature materials such as Kevlar®, Nomex®, fiberglass, etc.

Low-temperature substrates

Traditionally, the effective use of release products on fabrics such as polyester has not been possible due to the temperature sensitivity of the substrate.

Now, new low-cure products developed by Whitford make such applications not only possible but a reality — even on cotton.

High-temperature substrates

Whitford has developed two series of special finish/coating systems that provide outstanding release properties to belting woven from Aramid® or glass:

1. 60-080 Series for food applications and…
2. 60-010 Series for non-food applications.

Typical applications:

Belting: Whitford's finishes/coatings improve the performance of a conveyor belt on:

1. The running side.
2. The top side.
3. Even the inside.
   

Example: Finishing the running side of a belt lowers friction and adds to the belt's abrasion resistance. This is ideal for conveyors of parts as well as people, and works perfectly on low-temperature finishes, polyester, polyamide, polyurethane. The system: Ravlex 60-210/G1530.	Ravlex 60-210/G1530 reduces friction by 33% for smoother, easier belt operation and longer belt service life.
Unfinished textile after 1,000 cycles (Whitford abrasion test TM 135C). Severe abrasion. Many of the woven fibers are broken. The belt is about to fail.	Ravlex-finished textile after 1,000 cycles (Whitford abrasion test TM 135C). No fiber damage evident. The belt is hardly worn and continues to perform.
Example: Ravlex finishes/coatings significantly improve the abrasion resistance of textiles used to strengthen rubber conveyor belts. The system: Ravlex 60-112A/G0710 and Ravlex 60-112B/F9138.	Unfinished textile versus same textile finished with Ravlex 60-112. The unfinished version can accept only minimal deformation, while the Ravlex-finished version accepts substantially more deformation.

There are many treatments to help prevent the passage of water through fabric. All do something:

• Some repel water better.
• Some last longer.
• Some enhance the tear strength of the fabric.
• Some have better weathering properties.

Ravlex provides all four benefits in the same finish/coating. This waterborne system (Ravlex 60-620 and Ravlex 60-420) is ideal for use on:

• Tents
• Garden/patio furniture
• Sailcloth, etc.

The Ravlex 60-620/60-420 system is:

• Waterborne
• Capable of achieving in excess of 2m hydrostatic head
• Perfect for cotton, polyester, polyamide fabrics
• Less than $0.80 per square meter in cost.

Coatings for breathable materials

Whitford makes a line of water-repellent finishes/coatings for breathable textiles.

Finishes for specialist industrial applications

Whitford also offers a variety of finishes/coatings for these industrial applications:

1. Gaskets
2. Reprographic textiles
3. Automotive textiles
4. Filtration textiles
5. "Quiet" textiles
6. Lighter, more efficient sails.
