2. Product Features

  1. High-efficiency inhibition for platinum catalyzed addition silicone system, no impact on silicone mechanical properties after complete curing.
  2. Excellent compatibility with all vinyl silicone raw materials, no stratification, no precipitation after mixing.
  3. Low dosage, stable inhibition effect, adjustable retardation time according to addition amount.
  4. No toxic heavy metal, low odor, meets food contact & electronic grade environmental standards.
  5. No yellowing after high-temperature vulcanization, keeps silicone transparent and bright.
  6. Good storage matching: mixed silicone base with inhibitor can be stored for 3–30 days at room temperature depending on dosage.

3. Advantages

  1. Precise curing delay: Effectively prevent premature crosslinking during silicone mixing, printing, coating, injection molding and extrusion.
  2. Wide applicable temperature window: Suppress room-temperature curing reaction while release inhibition rapidly under heating condition.
  3. No negative influence on finished silicone: Maintain original tensile strength, elongation, hardness and adhesion of silicone products.
  4. Environmentally friendly formula: Halogen-free, RoHS compliant, suitable for medical, food and electronic silicone accessories.
  5. Easy operation: Directly add into vinyl silicone compound and stir evenly without special auxiliary solvents.
  6. Long service life of mixed silicone stock: Greatly reduce material waste caused by fast spontaneous curing.

4. Application Fields

  1. Liquid silicone injection molding: Baby silicone products, kitchen silicone utensils, silicone molds
  2. Silicone coating & printing: Silicone release coating, fabric silicone coating, screen printing silicone ink
  3. Electronic silicone materials: Potting silicone, thermal conductive silicone gel, electronic sealing silicone
  4. Silicone adhesive & sealant: Two-component addition type silicone sealant, transparent silicone glue
  5. Mold making silicone: Handmade craft molds, jewelry casting silicone, candle mold silicone
  6. Medical grade silicone: Medical catheter, silicone protective parts, disposable medical silicone accessories
  7. Extrusion silicone products: Silicone tubes, silicone strips, high-temperature silicone profiles。

5.Usage Instructions

Add the silicone inhibitor into vinyl silicone base material proportionally, stir uniformly at room temperature, then mix with platinum catalyst and hydrogen silicone oil before molding. Higher dosage leads to longer working time and needs higher curing temperature or longer heating time for full vulcanization.


6.Package & Storage

Standard package: 1kg / 5kg / 20kg plastic drum. Keep sealed, store in cool, dry and ventilated warehouse, avoid direct sunlight and high temperature environment. Keep away from strong oxidants.
