Silicone sealant for fire protection
JS-701 fire-resistant silicone sealant is a single component, neutral curing silicone sealant. JS-701 product can produce superior adhesion to most building materials.
Product features
1. Easy to use: can be squeezed out for use at any time;
2. Excellent thixotropy and extrudability, which can be extruded at - 5 ℃ - 40 ℃;
3. Neutral curing: suitable for most building materials without adverse reactions or corrosive effects:
4. When encountering an open flame, it does not support combustion and extinguishes itself without fire;
5. After curing, maintain good elasticity under environmental conditions of -25 ℃ -50 ℃.

- JS-701 fire-resistant silicone sealant is not suitable for structural assembly. It should not be used in the following situations:
- 1. All materials that can exude grease, plasticizers, or solvents, as well as certain unvulcanized or partially vulcanized rubbers and tapes;
- 2. Closed areas (silicone sealant needs to be cured with moisture in the air);
- 3. Long term immersion and year-round underground humid environment;
- 4. The paint surface may cause sealing failure due to cracking or peeling of the paint film;
- 5. Frosted or damp surfaces:
- 6. Will come into direct contact with the surface of food;
- 7. Places susceptible to mechanical wear and tear;
- 8. Avoid contact with rubber materials (such as rubber strips, rubber pads, etc.) to avoid yellowing;
- 9. Avoid contact with acidic or alkaline substances (such as exterior wall cleaning solution) to avoid discoloration;
- 10. When the surface temperature of the material is below -5 ℃ or exceeds 40 ℃, construction is not suitable;
- 11. All building materials used in engineering have successfully passed adhesion, compatibility, and contamination tests.
Color products offer commonly used standard colors: black, white, and other colors can also be provided according to customer needs.
