- Do not contact uncured sealant products with food or cosmetics;
- Uncured sealant should not come into contact with the skin for a long time;
- If the sealant accidentally enters the eyes, it must be immediately rinsed with a large amount of water and then checked by a doctor;
- Place the product out of reach of children.
This product can be colored using traditional methods after surface drying, including epoxy resin and acrylic acid coatings. Coatings containing high solvent components such as glossy enamel or high oil based coatings can cause the adhesive surface to become soft. It is recommended to use water-based environmentally friendly coatings.
In order to achieve the best appearance and performance, the coating must be close to the tensile strength of this product. For areas with adhesive thickness less than 3mm, coloring can be carried out after 24 hours. For thicknesses greater than 3mm, coloring can be carried out after 48 hours.
JS-905 silane modified sealant is a 500ml aluminum plastic film soft packaging.
It is recommended to store in a cool and dry place at 5-25 ℃ for a storage period of 12 months.
