2. In the case of low humidity (<50% RH) or large temperature difference between day and night (>15 ℃), the adhesive joint may bulge, but it does not affect the sealing performance;
3. It is not suitable for all materials that may exude oil, plasticizers, or solvents, such as the surface of oil soaked wood;
4. It is not suitable for use in poorly ventilated areas, as the sealant needs to absorb moisture from the air and solidify;
