FREKOTE AQUALINE R-150

Main features

  • Non-Flammable Mold Release Formulation
  • Natural/Synthetic Rubber Release and Slip
  • 60 to 200 deg C Mold Operation

Product Description

LOCTITE® FREKOTE® R-150™, formerly known as AQUALINE® R-150™, is a water-based, heat-curing mold release agent for demanding rubber molding processes, particularly those involving highly abrasive compounds. Applied as a finely atomized spray to a preheated mold, it chemically bonds to the surface and forms a thin, inert, thermally stable release coating. The product supports the release of natural and synthetic rubber compounds, thermoplastic urethanes, and certain solid polyurethane cast elastomers while providing release and slip performance across mold application temperatures from 60 to 200°C.

Key features

  • Water-based formulation: Supplied as a non-flammable, translucent emulsion with mild odor.
  • Release and slip performance: Recommended for demanding rubber molding applications, including highly abrasive compounds.
  • Heat-curing release coating: Forms a thin, inert coating on preheated molds and supports multiple releases.
  • Broad mold-temperature window: Applied to molds operating from 60 to 200°C.
  • Freeze/thaw stable: Supports storage and handling where temperature cycling may occur.

Applications / Suitable for

  • Natural and synthetic rubber molding compounds
  • Highly abrasive rubber compounds
  • Thermoplastic urethanes
  • Certain solid polyurethane cast elastomers

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.
0.98–1.02
Thermal Properties
Temperature Resistance
Temperature resistance is the maximum temperature that the material or product can withstand for a period of time. The temperatures listed should be considered as guidelines for an operating temperature of about 30 minutes. Typically, the material can withstand much longer times at temperatures about 20°C lower and can withstand much higher temperatures for short, intermittent times.
