GP-187 is an Isopropyl Alcohol - based solution of Methyl Silicone Resin. The resin cures to a soft, pliable consistency when GP-187 is applied to substrates and solvent is allowed to evaporate. Heating at elevated temperatures (100° C or higher) accelerates curing reactions, yielding a clear, hard resin film. Some of the special properties of GP-187 are listed below:

  • Excellent Film-Forming Properties
  • Weather and Heat Resistant films
  • Water Resistant (after application)
  • Fast Evaporating Solvent
