01 — Product description
An inorganic coating, not a paint
Vermiculite emulsion is an inorganic suspension made from vermiculite as the raw material and purified water as the solvent. It is an inorganic refractory material that is coated on the surface of various materials to enhance the refractory and fire-retardant performance of the substrate. The usual substrates are refractory fiber materials such as ceramic fiber cloth and fiberglass cloth.
| Item | Value |
|---|---|
| pH value | 6 – 8 |
| Non-volatile content | 18 % ± 1 % |
| Viscosity (25 C, 4# spindle at 30 rpm) | 3000 – 12000 mPa·s |
The product is packaged in drums. It is used for fire-retardant enhancement coating on the surface of various substrates, and is suitable for refractory fiber materials such as ceramic fiber cloth and fiberglass cloth.
Working condition suitability and restrictions
Suitable for conventional room-temperature coating processing and dry static fire protection. After coating, the film must be completely dried and cured before being put into high-temperature use. It is not suitable for long-term water immersion, strong acid or alkali corrosion or high-speed erosion, which damage the coating structure and reduce protection effectiveness. All technical data are for reference; users should test suitability and follow the relevant safety regulations.
02 — Characteristics
Inorganic suspension
Vermiculite dispersed in purified water, without organic binder chemistry.
Coating application
Applied to the surface of a substrate to raise its refractory and fire-retardant performance.
Suits fiber textiles
Intended for refractory fiber materials such as ceramic fiber cloth and fiberglass cloth.
