SILISIL RTV ZCX 15-3 CATALYST

SILISIL ZCX 15-3 CATALYST is the crosslinking component of the condensation-curing two-component silicone ZCX 15-3, which vulcanizes at room temperature. The system offers a low Shore A hardness of approximately 14, high tear strength, and low dimensional change, and is not inhibited by plaster, clay, or cement. The catalyst is weighed into the base exactly in a 10:1 ratio (base to catalyst); homogenize both components before use and process on clean, dry surfaces at room temperature.

Product Description

SILISIL ZCX 15-3 CATALYST — ZCX

SILISIL ZCX 15-3 CATALYST is part of the 2K system SILISIL ZCX — a condensation-curing silicone series for applications where classic tin crosslinking offers advantages over platinum systems in terms of cost, tolerance to contamination, and processing temperature..

Product Advantages

  • 2K addition system with precisely matched mixing ratio
  • Low shrinkage and dimensionally stable even after prolonged storage
  • High tear and tear propagation resistance
  • Excellent detail reproduction even at a microscopic level
  • Long mold life with proper processing
  • Compatible with common casting and molding materials

Typical Applications

  • General mold making: Classic impression for plaster, wax, and resin casting
  • Decorative Elements: Stamping dies, decorative parts, figures
  • Artist supplies: Sculpture and plastic reproduction
  • Construction and Architecture: Wall element and ornament molds

Processing and Mixing

  • For the exact mixing ratio, pot life, and demolding time, please refer to the technical data sheet (TDS) on this product page
  • Before processing, stir both components individually and then mix thoroughly in the specified ratio
  • Degassing under vacuum (30–50 mbar) eliminates air inclusions and improves surface quality
  • Processing ideally at 23 °C and 40–60 % relative humidity
  • Contamination by sulfur, amines, tin catalysts, or PVC must be avoided in platinum-crosslinked systems — they prevent curing

Storage and Shelf Life

  • Store in unopened original container at 5–25 °C, dry and protected from direct sunlight
  • Shelf life from the manufacturing date specified in the TDS — typically 12–24 months
  • After opening, reseal carefully

Included Documentation

  • Technical Data Sheet (TDS) in German, English, and French
  • Safety Data Sheet (SDS) according to REACH
  • Batch certificate on request
