Glass rubber powder is a one-component, elastic, deacidifying type of room temperature vulcanized (RTV) silicone sealant. It is primarily made from silicone rubber and includes additives such as reinforcing agents, crosslinkers, antioxidants, accelerators, and plasticizers. This powder is processed to form a one-component RTV sealant that exhibits excellent resistance to atmospheric aging. It is suitable for sealing general building materials like glass, ceramics, aluminum alloys, oil-free wood, bricks, and ceramic tiles. While it can be used for waterproofing, it is not recommended for structural glass assembly.
When using glass powder, consider the following important points:
1. Application: One-component silicone glass glue can be used immediately after opening. It can be easily applied using a glue gun from a plastic bottle, and excess material can be smoothed out with a spatula or wooden chip.
2. Bonding Time: The curing process of silicone rubber starts from the surface inward. The drying and curing times vary depending on the type of silicone. For example, acid-type glue and neutral transparent glue usually set within 5–10 minutes, while neutral colored glue may take up to 30 minutes. If you use masking tape to cover an area, make sure to remove it before the surface begins to harden.
3. Curing Time: The thickness of the bonded layer affects the curing time. For instance, a 12mm thick layer of acid glass glue may take 3–4 days to fully cure, but the outer 3mm layer may be cured within 24 hours. After 72 hours at room temperature, the peel strength can reach about 20 lbs/in when bonding glass, metal, or most types of wood. If the joint is completely sealed, the curing time depends on how tightly the surfaces are closed. In an airtight space, the glue may never fully cure. Raising the temperature can soften the glue. The gap between two metal surfaces should not exceed 25 mm. Always check the bond thoroughly before using any equipment that relies on the seal.
During the curing process, acidic glass powder may emit a vinegar-like smell due to acetic acid evaporation. This odor will disappear once the product is fully cured and will no longer be noticeable.
4. Bonding: A. Clean the surfaces of metal and plastic thoroughly to remove any oils. For all surfaces except plastic, rinse them with acetone. Sand the rubber powder surface with sandpaper, then wipe it with acetone. Be cautious when using acetone, as it is a strong solvent. B. Apply the glass glue evenly to the prepared surface. When joining two surfaces, place one first, then press the other side firmly to expel air without squeezing out the glue. C. Allow the bonded item to cure at room temperature until the glass powder is fully set.
5. Sealing: When used for sealing, apply the glue in the same way as described above. Force the glue into the joint or gap to ensure full contact with the surface.
6. Cleaning: Before the glue cures, it can be wiped off with a cloth or paper towel. Once cured, it must be removed using a scraper or solvents like xylene or acetone.
7. Safety Notes: Acidic glass glue releases acetic acid during curing, which can irritate the eyes and respiratory system. Neutral alcohol-based glues release methanol, which is potentially carcinogenic and can cause skin and respiratory irritation. Always use this product in a well-ventilated area. Avoid direct contact with eyes or skin, and wash hands before eating or smoking. Do not ingest the product. Keep it away from children. If the product gets into your eyes, rinse immediately with water and seek medical attention. Fully cured glass glue is safe to handle.
8. General Guidelines: Read the correct application instructions before use. Pay close attention to safety information and health warnings provided by the manufacturer.
9. Storage: Store the glass glue in a cool, dry place below 30°C. Acidic glass powder typically has a shelf life of over 12 months if unopened. Neutral weathering and structural glues can last more than 9 months. Once opened, use the product quickly. If not fully used, reseal the container tightly. When reusing, unscrew the cap to clear any blockage or replace the nozzle if necessary.
Outdoor Garden Light is typically used to illuminate areas such as gardens, lawns, pathways, and courtyards. They can be pole-mounted, wall-mounted, or ground-mounted and typically use LED or other energy-efficient bulbs to provide efficient lighting. Outdoor Garden Lights can also be equipped with sensors to automatically turn on or off when detecting people or animals, saving energy and increasing safety. Additionally, they can have different designs and colors to meet various outdoor design needs.
