Epoxy Research Resin RSL-4515 / EPIKURE™ Curing Agent 3300 and Epoxy Research Curing Agent RSC-4577

Description

Epoxy Research Resin RSL-4515 / EPIKURE™ Curing Agent 3300 and Epoxy Research Curing Agent RSC-4577

 

 

Introduction

Epoxy Research Resin RSL-4515/EPIKOTE Curing Agent 3300 or Epoxy Research Curing Agent RSC-4577 is based on a toughened epoxy cured with very low viscosity cycloaliphatic amines. The systems low viscosity and high toughness make it favorable for good fiber wet-out for filament wildings for all composite pressure vessels (including Type IV vessels).  It will allow the manufacture of an all carbon tank without increase in cost (via reduction in wall thickness).

 

Suggested Uses

  • Composite Structures
  • Pressure Vessels

 

 

 

Features

  • Low Viscosity
  • Good Elongation
  • High Toughness

Mixing Instructions

The stated mixing ratio should be followed carefully. Adding more or less hardener than desired will result in an incomplete cure with limited performance that cannot be corrected. Resin and curing agent must be mixed carefully. Mix until no clouding is visible in the mixing container.  Special attention must be paid to the walls and bottom of the mixing container when mixing by hand.
