LOCTITE TW 040

• It is an excellent choice for protecting primary and secondary weatherstrip seals due to its premium abrasion resistance and squeak and itch prevention.
• Functional performance of seals for ice release, scuff resistance and solvent resistance is enhanced with this.
• This coating is well suited to protect EPDM rubber from glass abrasion in automotive window channel applications.
• The cured coating is flat black in appearance, flexible, excellent in wear resistance, and not abrasive to painted surfaces.
• The ease with which is prepared and sprayed onto parts allows for maximum productivity and uptime.
• Its excellent hiding power allows for more usable profile as surface imperfections are covered.

Features:

• Effective noise-suppression for most environments and seal designs.
• Multiple usage for sponge and dense seal substrates.
• UV tracer content
• Good coverage properties for covering surface defects

Benefits:

• Customer satisfaction in minimizing squeak and itch annoyance
• Inventory simplification for cost-effective operations
• Confirms application of coating onto seal, avoiding costly scrap
• Less scrap production, increasing revenues and lowering operational costs

• Vinyl extrusions
• Vinyl molded parts
• Rubber extrusions
• Door, trunk, and sunroof gaskets
• Rubber molded parts
• Weatherstripping (EPDM)

Coverage:

• 575 ft²/gal at 1 mil (25 μm)

Cure:

• Typical cure schedule:
  • 3 minutes at 177°C (350°F)
  • 5 minutes at 149°C (300°F)
• This information is only a guide to curing, and your curing system may take more or less time to cure on your substrate.

Clean Up:

• Use cool water to flush lines and guns.

Mixing:

• It is a two-component coating.
• Mix only the amount of coating to be used within 12 hours with Loctite TW 422 crosslinker or within 30 days with TW 423 crosslinker.
• Mix until uniform. With component “A” mixing, slowly blend component “C” into component “A” (5 parts by weight of component “C” into 95 parts by weight of component “A”).
• To avoid foaming, do not use high-speed mixers or shakers.

Application:

• It is designed to be spray-applied in-line onto warm to hot rubber extrusions, or molded parts that have a surface temperature less than 93°C (200°F).
• For best adhesion, surface pretreatment with corona, plasma or primer is required prior to applying LOCTITE TW 040.

• Applicable for meeting most OEM coating specifications upon adequate cure and application

• Final required film thickness and performance are dependent on seal/vehicle architecture and substrate properties such as hardness, smoothness and surface chemistry.
• Best glass run abrasion resistance is usually achieved at 25-30 μm dry film thickness.

• Shelf life for this product is 12 months from date of qualification under original seal, when stored between 10°-27°C (50°-80°F).
• Return to room temperature and stir gently before using.
• Do not freeze. Keep container tightly closed when not in use.
• Store in a cool, well ventilated area.
• Empty containers may retain hazardous properties.
