Abrasive Belt Adhesives-Image

Sheldahl™ brand polyurethane adhesives are designed to be used in conjunction with an isocyanate curing agent as a two-component system. These systems produce a tough, flexible, temperature and chemical resistant bond. Our adhesives are specifically designed for splicing abrasive belts and may be used as a general adhesive for plastics, rubber, fabrics, leather, wood and paper.

PRODUCT DESCRIPTION

Sheldahl™ Brand Polyurethane Adhesive is designed to be used in conjunction with an isocyanate curing agent as a two-component system. These systems produce a tough, flexible, temperature and chemical resistant bond.

APPLICATIONS

Sheldahl™ Brand Adhesives are specifically designed for splicing abrasive belts and may be used as a general adhesive for plastics, rubber, fabrics, leather, wood and paper.

GENERAL PROPERTIES

  • Composition -Linear polyester-urethane
  • Form - Light syrup
  • Color - Pearl gray/straw
  • Recommended Isocyanate Curative - Desmodur® RE or RFE
  • Pot Life - 4-6 Hours after Curative addition, depending on ambient conditions

Sheldahl Brand Adhesives are used in abrasive belt manufacturing in three ways:

1. Applying adhesive to the belt ends, forming an overlap and bonding using heat and pressure.

2. Applying adhesive to the belt ends and to Uncoated Splicing Tape (PBIM-1002) then adhering the butted ends of the belt with the tape and bonding using heat and pressure.

3. Applying adhesive to the belt ends, then adhering the butted ends using Coated Splicing Tape (PBIM1001) and bonding using heat and pressure. Sheldahl Brand Adhesive may be applied using a brush, roller, knife, or by spraying. A045500 is particularly well suited for spraying because it maintains a low viscosity at higher solids. A065100 is recommended for roller and tape coating. A066700 is lower viscosity adhesive without the aroma of MEK.
