PUT3220-2L Two-component Polyurethane Potting Compound
PUT3220-2L is ideal for potting and sealing various lighting, electronic, and electrical items. It has a low mixing viscosity, excellent fluidity, easy pouring capabilities, and is easy to work with. Its primary uses include waterproofing, protection, sealing, filling, and insulation. Once cured, it forms a strong adhesive colloidal structure with good electrical properties. This product meets RoHS and Reach environmental standards as well as flame retardant requirements.
Features and benefits
- PUT3220-2L is a two-component, high-performance (high thermal conductivity, high flame retardant) polyurethane potting material.
- PUT3220-2L consists of main agent and curing agent
*A glue: curing agent/cured isocyanate.
*Glue B: main agent/polyol.
