LOCTITE SF F720

This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be used with chlorine or other strong oxidizing materials.

Surface Preparation:

• To maximize bond strength, clean and roughen surface with steel wool or fine abrasives to increase adhesion (suggested for flat metal surfaces and simple design.
• A high grade zinc oxide (paint) primer can also be used to improve adhesion.

Color Guard Application:

• Dipping
  • Dipping will always give you the best results and most uniform coating.
  • It is ideal for dipping small parts - tool handles, rope ends, brackets, knobs, and valve handles.
  • Larger packages can be purchased for dipping large or multiple objects.
  • Surfaces to be coated must be cleaned. Use of Loctite® SF 7070 is recommended to eliminate grease, oil and dirt. Rust or loose paint can be sanded or wire brushed as needed.
  • Before dipping object, devise a method to hang object to dry - string, wire or a clamp are suggested.
  • Do not apply in direct sunlight or under windy conditions. Slowly immerse item and slowly withdraw (approximately 2.5 cm every 5 seconds).
  • Coating will be uneven, sag or drip when object is withdrawn too rapidly.
  • Hang part to dry. Do not hang above an open can of LOCTITE® SF F720.
  • Vapors will inhibit proper drying and dripping may results. Allow 20 minutes between coats.
  • Drying time @ 25°C is approximately 4 hours for each coat applied.
• Spraying - Industrial:
  • For large applications, use an industrial airless gun or pressure pot gun. Do not use a Siphon Gun.
  • Pressure pot spray setting is 20 psi and gun pressure is 40 to 60 psi.
  • Hold gun 25 to 30 cm away from surface and apply a uniform wet coat.
  • Several coats may be applied to achieve the desired thickness - two to three coats are recommended for a 12 mil thickness.
  • Allow 20 minutes between coats. Drying time @ 25°C is approximately 4 hours for each coat applied.
  • Spray equipment can be cleaned with naphtha.
• Brushing:
  • Brushing should be reserved for applications that can neither be dipped or sprayed. Brushing offers the least desirable results.
  • Dilute LOCTITE® SF F720 to desired consistency with naptha (1 part naptha to 2 parts LOCTITE® SF F720 is recommended).
  • For metal surfaces, clean and roughen with steel wool or fine abrasives to increase adhesion of the LOCTITE® SF F720, or use high grade zinc oxide (paint) primer.
  • Brush surface in one direction only. Of the three methods of coating parts, brushing offers the lease desirable results. You may find that the surface is properly protected, but the appearance of the coating may be irregular.
  • Several coats are recommended for maximum protection. Allow 20 minutes between coats. Drying time @ 25°C is approximately 4 hours for each coat applied.
  • Brush can be cleaned with naphtha.

Subsequent Application:

• Once applied, LOCTITE® SF F720 does not have to be removed for additional coats.
• New coats will fuse to old coats during air drying.

Clean Up:

• Cured LOCTITE® SF F720 may be wiped clean with Loctite® SF 7070, or naphtha.
