INSULGEL 70 CC is a semi-flexible epoxy compound formulated with low shrinkage and a low coefficient of thermal expansion. Thanks to its flexible epoxy resin base and advanced filler technology, it provides superior thermal shock resistance, reduced internal stress, and improved adhesion to components. Multiple curing agents (B-1, Insulcure 9, Insulcure 11B) are available to meet specific processing needs—ranging from fast curing for small parts to extended pot life for large batches or high-temperature performance.
Key Features & Benefits:
Excellent thermal shock resistance.
Low shrinkage and low CTE for stress reduction.
Multiple curing options (room temperature, fast cure, heat cure).
Strong adhesion and mechanical resilience.
Service temperature range up to –55°C to +155°C depending on hardener.
Shelf life: 12 months (all components).
Encapsulation and potting of sensitive electronic or electrical components.
Adhesive or casting compound where low CTE and thermal cycling resistance are required.
High-reliability environments (electronics, aerospace, industrial power systems).
