SiO-718 Room Temperature Curing Silicone Resin Emulsion
SiO-718 Waterborne High-Temperature Silicone Resin Emulsion (Room Temperature Curing Type) is an upgraded version of SiO-715. Unlike SiO-715, which requires high-temperature curing, SiO-718 can achieve room temperature curing, overcoming the limitations of large facilities and equipment that cannot be baked. The product is packaged in two components.

Typical Physical Data (SiO-718A)
Curing Conditions
Room temperature curable, fully cured in one week. Curing can be accelerated at temperatures below 80℃.
Usage Recommendations
1. It is recommended to first prepare waterborne non-resin color paste and then use it in combination with waterborne silicone resin emulsion.
2. SiO-718A must be used with a curing agent for deep curing. The addition amount of curing agent SiO-718B is 10% of SiO-718A. The curing agent must be independently packaged and added to the main component before use, thoroughly mixed, and then applied. The mixed coating must be used within 8 hours; otherwise, increased viscosity or gelation will render it unusable. The coating should be prepared as needed to avoid waste.
3. If the formulated coating is too viscous, a small amount of water can be added for dilution.
4. The applied coating can cure at room temperature but requires 7 days to fully cure, with performance testing conducted after this period. To achieve excellent heat resistance and physical mechanical properties more quickly, curing can be accelerated at temperatures below 80℃. If no baking equipment is available, a small infrared lamp or a hot air blower can be used.
Packaging and Storage
1. Packaging Specifications: 50 kg plastic barrels.
2. Store in a ventilated, cool place above 0℃, not exceeding 40℃. Transport as non-hazardous goods.
Shelf Life
Store in a sealed container for 6 months. (Each product label will indicate the "best before" date. Storage beyond the indicated date does not necessarily mean the product cannot be used, but the relevant properties should be rechecked to ensure quality).
