VS-SR988
VOLSUN
VS-SR988 is a one-part heat-curing silicone rubber sealant designed for sealing, bonding and protection of mechanical, electronic and electrical equipment. It is supplied as a grey paste and provides flame retardancy, waterproof sealing performance and good adhesion to various metals.
The material can be stored at room temperature in its original sealed package and cures quickly under high-temperature conditions. With good thixotropy, the applied sealant bead can hold its shape without collapse, making it suitable for dispensing, local sealing and protective bonding applications where controlled placement is required.

Clean the substrate surface before bonding or sealing to remove dust, oil and other contaminants.
Cut the nozzle to the required bead size and install the package into a dispensing gun.
Apply the sealant evenly to the target bonding or sealing area.
Assemble the parts immediately after applying the sealant to the substrate surface.
Cure the material under the recommended heat-curing conditions, such as 100°C × 3 h, 130°C × 1 h or 150°C × 30 min.
After opening, use the product as soon as possible. For reuse, remove or squeeze out any cured material at the nozzle before dispensing again.
Keep the application area clean and free from large debris, dust, oil and other contaminants to avoid affecting adhesion.
Before the material is fully cured, avoid contact with other objects to prevent surface defects or performance issues.
Avoid contact with eyes and mouth. In case of accidental contact, rinse with clean water and seek medical attention if necessary.
Follow the recommended heat-curing conditions and verify compatibility with the substrate before mass application.
Keep the product cap tightly closed and store it in the original packaging at room temperature and away from light
Product shelf life is 6 months from the production date
VS-SR988 is supplied as a one-part paste, so no mixing is required before dispensing. Its heat-curing process supports faster curing at elevated temperatures, and its thixotropic behavior helps the applied bead hold its shape without collapse. This makes it suitable for controlled sealing and bonding applications in mechanical, electronic and electrical equipment.
VS-SR988 is designed to provide good adhesion to various metal substrates. For plastics, coatings or other materials, compatibility and adhesion should be verified under actual application conditions before mass production.
Listed curing conditions include 100°C × 3 h, 130°C × 1 h and 150°C × 30 min. Actual curing performance may vary depending on sealant thickness, part size, substrate material and heating conditions. Users should verify curing results under actual production conditions.
VS-SR988 is used for sealing, bonding and protection of mechanical, electronic and electrical equipment.
