Loctite© Resinol RTC

ResinolTM RTC Porosity Sealant

INTRODUCTION 
Loctite© Resinol RTC is a low viscosity water washable sealant for the impregnation of porous materials. The sealant is designed to cure anaerobically at room temperature.
     The vacuum impregnation process consists of a few basic steps. First, the air is evacuated from the internal porosity of the part being processed. The part is then repressurized while immersed in Resinol RTC. The low viscosity liquid sealant flows into the evacuated pores and polymerizes to form a solid thermoset plastic. The film of Resinol RTC left on the surface of the part remains liquid and is easily removed by washing the parts in plain water.
      Resinol RTC is formulated with a unique proprietary surfactant monomer which reacts within the sealant to form part of a densely crosslinked polymer. The use of this reactive surfactant makes it possible to offer a sealant that can be washed off without detergents and yet not compromise the performance characteristics of the cured polymer.

IV. SOLVENT RESISTANCE
  In general, Resinol RTC is resistant to degradation by hydrocarbon solvents (e.g. gasoline, motor oil, transmission fluid) fluorinated solvents (e.g. Freon 12), water, alcohols, and dilute aqueous solutions of acids and bases. As an illustration solvent absorption data for water, gasoline and ethylene glycol/water (50/50) are presented below.
Test Sample Absorption (% original sample weight)

Water  0.82 1.37 2.57
Gasoline 0.01 0.17 0.30
Ethylene glycol/water 0.45 0.82 1.48
   Cast 1" x 3/8" samples were immersed in solvent at top temperature. Solvent absorption with tie is reported as percentage of original sample weight. Samples showed no visual evidence of degradation.
   Data concerning resistance to specific solvents and chemical media will be produced on request.
V. CURE MECHANISM
   Liquid Resinol RTC cures to form a thermoset plastic by a free radical polymerization reaction mechanism when contained and away from air.
VI. CURE RATE
   Accelerated Resinol RTC that is trapped within a clean porous metal part will typically cure completely within several hours room temperature.
   The polymerization of Resinol RTC is initiated by chemical interaction with Locitete PMS Accelerator and with certain metal surfaces. The cure rate is influenced by several factors.
*The cure rate becomes more rapid as the concentration PMS Accelerator is increased
*The cure rate is increased by contact with certain metal surfaces.
*The cure rate is temperature dependent and becomes more rapid as the temperature is increased.
*Polymerizaton is inhibited by the presence of oxygen.
*Ploymerization is inhibited by the addition of Loctite PMS Stabilizer.
