COOLTHERM SC-6730
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Room-Temperature Thick-Section Cure
- 3.0 to 10.0% Mix Concentration
- Blue-Green Visual Mix Indicator
Product Description
CoolTherm™ SC-6730 Hardener is a high-viscosity catalyst for use with RTV condensation-cure silicone resins when fast room-temperature cure in thick sections is required. The blue-green liquid supports visual confirmation of thorough mixing and may be used at concentrations from 3.0% to 10.0% by weight, depending on the cure rate required. It cures deep sections without exotherm and provides documented resistance to copper corrosion. Specific mix ratios, application instructions, and cure schedules depend on the selected resin system.
Key features
- Deep-section cure: Supports room-temperature curing in thick sections without exotherm.
- Adjustable catalyst concentration: May be used at 3.0% to 10.0% by weight, depending on the cure rate required.
- Visible mixing indicator: Its blue-green color supports visual examination of mixing uniformity.
Applications / Suitable for
- RTV condensation-cure silicone resin systems
- Thick-section silicone curing requiring fast room-temperature cure
