Product Introduction
Momentive RTV-664A/B is a high-durometer (62 Shore A), platinum-cured silicone rubber formulated for industrial mold-making. With a 10:1 mix ratio, it combines RTV-664A base (153,000 cps) and RTV-664B blue catalyst (6,000 cps) to deliver exceptional dimensional stability, near-zero shrinkage, and extended worklife (2 hours). Ideal for high-volume production lines, it resists abrasion and chemicals while enabling rapid demolding within 18 hours.
Advanced Properties
- Precision Stability: Shore A 62 hardness ensures rigid molds with <0.2% linear shrinkage, critical for micron-level accuracy.
- Robust Mechanicals: Tensile strength (933 psi) and high tear resistance (122 ppi) prevent mold degradation during repeated casting.
- Optimized Processing: 120,000 cps mixed viscosity allows complex cavity filling; vacuum degassing eliminates bubbles in 2 minutes.
- Thermal Endurance: Stable from -60°C to 200°C (-75°F to 392°F), suitable for polyurethane, epoxy, and low-melt alloys.
Application Scenarios
Validated industrial use cases include:
- Automotive: Mass production of PU gaskets, interior trim components.
- Consumer Goods: Replication of textured surfaces (e.g., synthetic leather, wood grain).
- Industrial Casting: High-abrasion parts like hydraulic seals or conveyor belt guides.
