SILISIL PC Curing Agent PU

SILISIL PC-Curing Agent PU – Crosslinking agent for condensation silicones

SILISIL PC-Curing Agent PU isa high-performance, single-component crosslinking agent based on tin and silane for curing condensation silicones. The formula is specially designed for industrial applications that require precise control of cross-linking and high thermal stability. Due to its non-flammable formulation, SILISIL PC-Curing Agent PU is ideal for professional use in safety-critical processes.

Product features

• • • Catalyst for RTV condensation silicones
    • Good dosability (viscosity approx. 200 cP)
    • Long processing time with reliable final cross-linking
    • Contains bis(neodecanoyloxy)dioctylstannane and triethoxyoctylsilane

Suitable silicones & applications

• • • 1K condensation-curing silicones
    • Potting compounds, silicone formulations, RTV systems
    • Mold making, electronics casting, technical sealing

Typical areas of application

• • • Use in safety-relevant sealing systems where volatile solvents or flammable hardeners must be excluded
    • Manufacture of silicone molds, sealants, or pastes
    • Processing under industrial conditions with a focus on long-term stability and minimal shrinkage
    • Ideal component for customer-specific RTV-2K systems

Processing instructions

• • • For industrial and professional applications – not suitable for consumer products
    • SILISIL PC-Curing Agent PU is typically dosed at a ratio of 2–5% to the silicone base.
    • Use only with compatible RTV condensation systems.
    • Adhere strictly to the mixing ratio, as an excess of tin can lead to cross-linking problems.
    • Avoid contact with water—alcoholic byproducts are formed.

Safety-related information

• • • Contains substances toxic to reproduction (e.g., dioctyltin dilaurate – Repr. 1B H360D)
    • May cause damage to organs through single or repeated exposure (H371, H373)
    • Use only in well-ventilated work areas.
    • Wear personal protective equipment (EN 166, EN 374, EN 14605)

Storage

• • • Store unopened at 5–25°C.
    • Protect from moisture and sunlight
    • Store in well-ventilated, fireproof rooms.
    • WGK 3 – highly hazardous to water
    • Do not store with food
