JDB7901 silicone adhesive sealant
JDB7901 is a solvent free, corrosion-free single component silicone adhesive sealant. When placed in humid air and cured at room temperature, it does not drip, has continuity of adhesion, and has excellent adhesion to various substrates. After curing, it will become a flexible silicone rubber.
Feature
● Absorbs moisture from the air and solidifies at room temperature, making it easy to use;

 Fast curing speed, suitable for conventional bonding operations;

 Extremely excellent moisture and heat resistance at 85 ℃ × 85% RH × Excellent performance under 1000h damp heat test;

● It has long-term adhesive properties for commonly used materials such as aluminum, PPO, Tedlar backboard, etc. And it has excellent flexibility, moisture-proof and shockproof functions, preventing water vapor, environmental erosion, as well as mechanical, thermal shock, UV light and other damage;

 Excellent ozone, UV, weather and aging resistance, suitable for use at -45 ℃ to 200 ℃.

Usage method
Instructions for use

 Clean and dry the surface of the adhesive object, and remove any pollutants such as rust, dust, and oil that may affect adhesion.

 Extrude the adhesive with a special tool and apply it to the cleaned joint surface.

 Under the condition of 23 ± 2 ℃/50 ± 5% humidity, the surface should dry within 20 minutes and cure for about 2 mm of adhesive thickness for 48 hours. Low temperature and dry climate conditions require an extension of curing time.
