density making it especially suitable for lightweight, high performance composites using a variety of
reinforcements.
80LS-19 System USES
Lightweight composites
Hand lay up, vacuum bagging and RTM
Marine equipment such as sail & surf boards application
Systems where very light color is required
Repair applications, laminating, bonding
and sealing
80LS-19 System PERFORMANCE BENEFITS
Superior fatigue and toughness properties
Good adhesion to fabrics, core materials,
wood and metal
Good moisture exclusion
Excellent wet out and air release
Non Staining
Excellent clarity and transparency
CURING AO 80LS- 19 SYSTEM
AO 80LS- 19 System mixes maintain good working properties until gelation takes place. Under some circumstances the
mixture may cure to a brittle B stage, but will temper to full cure over the next 48hours at 77 F. Minimum cure
temperature is 72 F/22 C. The system reaches maximum ambient cure after seven days at room temperature.
