HLD-9621 polyurethane potting compound

Polyurethane potting compound

Also known as Ulidang adhesive, it is mainly divided into two types: polyisocyanate and polyurethane.  Polyurethane potting compound is an important part of the rapidly developing polyurethane resin. It has excellent electrical properties and has been widely used in many aspects. It is one of the important varieties among the eight major synthetic adhesives.  Polyurethane potting compound has excellent impact resistance and shear strength, is suitable for various electrical sealing fields, and features excellent flexibility.

Characteristics and Applications

Polyurethane potting compound has excellent rubber-like properties and can adapt to the bonding of substrates with different thermal expansion coefficients. It forms a soft-hard transition layer between substrates, providing not only strong adhesion but also excellent cushioning and shock absorption functions.  The low and ultra-low temperature performance of polyurethane potting compound surpasses all other types of adhesives.  Two-component polyurethane electronic potting compound has superior properties such as low stress, heat and cold resistance, thermal conductivity, impact resistance, etc., features stable electrical properties, can be applied manually or mechanically, and can cure at room temperature or low temperature.  It is suitable for small and medium-sized electronic components, such as automotive ignition coils, solid-state voltage regulators, motorcycle electrical equipment, etc.  Igniters, capacitors, neon electronic transformers, ballasts, lighting starters, dry-type transformers, relays
