Usage Guidelines

Curing System

LC-1930 is pre-accelerated and requires only the addition of MEKP (methyl ethyl ketone peroxide) catalyst for curing. The pre-thixotropic properties eliminate the need for additional thixotropic agents.

Recommended Catalyst:

MEKP: 1.0-2.0% by weight depending on temperature and desired gel time

Application Method

Suitable for hand lay-up, spray-up, and contact molding processes. Excellent for vertical and overhead applications due to thixotropic properties.

Storage Conditions

  • • Store in cool, dry place (15-25°C)
  • • Keep away from heat sources and direct sunlight
  • • Ensure containers are tightly sealed
  • • Storage life: 3 months (uninitiated, dark place, 20°C) at 20°C
  • • Avoid freezing temperatures

Safety Precautions

  • • Use in well-ventilated areas
  • • Wear appropriate protective equipment
  • • Avoid skin and eye contact
  • • Keep away from ignition sources
  • • Follow local environmental regulations
