Suggested Uses

N/A L-3632 was designed for use in fiberglass sizing applications that require very good strength, abrasion-resistance and adhesion.

Characteristics

N/A

  • TEA-free, pyrrolidone-free, APEO-free
  • Forms medium hard, tough, flexible films
  • Good abrasion resistance
  • Superior, low temperature flex-crack resistance
  • Contains dipropylene glycol monomethyl ether

Application

N/A L-3632 may be used as a sole vehicle or blended with acrylic emulsions. Viscosity modification can be made with associative thickeners for application by spray, knife-over-roll, or other methods.

Curing

N/A Typical oven drying temperatures and dwell times for aqueous coatings are sufficient to produce optimal film properties. Do not use crosslinking agents for heat-seal coating applications.
