Hydroxy Polymer (107 RTV Silicone Rubber)
Reactivity: The terminal –OH groups readily condense with silane coupling agents, crosslinkers (e.g., alkoxysilanes, silicates, isocyanates) or moisture in air to form elastomers at room temperature (RTV).
This is a medium-to-high-viscosity, hydroxyl-terminated polydimethylsiloxane that serves as the backbone for RTV silicone elastomers, construction sealants, release coatings, textile finishes, and specialty polymer modifiers.
Technical Specifications:
Appearance: Smooth and fine viscous fluid, without precipitates that are difficult to disperse quickly and evenly.
Color: Colorless and transparent
Odor: No irritating odor
Leveling: Self-leveling
Tensile strength (Mpa): ≥ 2.8
Tear strength (KN/M): ≥ 6
Hardness (Shore A): 30-50
Elongation (%): ≥ 200
Linear shrinkage (%): ≤ 0.3
Main Applications:
Note：for reference only
Instructions for use:
Curing Systems: Typically combined with crosslinkers (alkoxysilanes, silicates) and condensation catalysts (organotin or titanate) to yield one-part or two-part RTV formulations. Cure time at room temperature: 30 min – 24 h; elevated temperatures (120–150 °C) accelerate curing.
Compatibility: Avoid prolonged contact with strong acids/bases, alkoxy silanes, or high-temperature steam to prevent premature crosslinking or depolymerization.
This product has good self-adhesion and can be cast or painted in batches.
