THI-VEX™ is made especially for thickening Smooth-On silicones for vertical surface application (making brush-on molds). Different viscosities can be attained by varying the amount of THI‑VEX™ added. THI-VEX™ is added as a percentage of Part A and must be thoroughly mixed with Parts A and B. THI-VEX™ is skin safe and certified by an independent laboratory.
Instructions
THI-VEX™ will not work with Mold Max™ 40, Mold Max™ 60 or Solaris™ silicones.
Safety - Use in a properly ventilated area (“room size” ventilation). Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk.
Store and use material at room temperature (73°F/23°C). This product has a limited shelf life and should be used as soon as possible.
MEASURING & MIXING - If using Mold Max™, the brush-on mold process can be shortened with Fast Cat™ 30 catalyst or Accel-T™ cure accelerator. Because silicones have a long pot life, time between coats can be 2–3 hours. Adding Fast Cat™ 30 catalyst or Accel-T™ cure accelerator will accelerate the brush-on mold making process down to a matter of hours.
Mixing - Add desired amounts of THI-VEX™ to material and mix thoroughly. Important: Be sure to scrape the sides and bottom of the mixing container several times while mixing. Be aware of your working time. Note: results may differ due to variables in temperature, humidity, etc.
Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.
