Semitransparent silicone sealant
JS-388 semi transparent silicone sealant is a single component, medium modulus, neutral curing adhesive. JS-388 semi transparent silicone sealant 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 ℃ to 40 ℃;
3. Good adhesion and excellent adhesion to most building materials;
4. Excellent weather aging resistance;
5. It is non irritating and non corrosive to metal, coated glass, mirror glass, concrete, marble, granite and other building materials, overcoming the shortcomings of acid glue (ordinary glass glue) corrosive materials.

- JS-388 semi transparent silicone sealant is not suitable for structural assembly.
- It is not easy to use 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.
