GLT-983 – Addition-Type Two Components Silicone Potting Sealant

Features and benefits

• High transmittance
• High purity
• Excellent moisture resistance
• Good adhesion
• Addition Reaction (Two Components)
• The hydrosilylation process of platinum catalyzed
• High optical transparency and good anti-foaming
• High dimensional stability, soft and bright after curing
• Suitable for potting protection of high-power electronic components.
• Good protection function for electronic components (such as
waterproof, moisture-proof, shock proof, anti extrusion, anti-aging and
other protection functions)
• Cured at room temperature or medium temperature (100°C),no any
by-product released during the curing .
