In addition, this rigid urethane potting compound adheres strongly to a wide variety of substrates, including metals, composites, glass, ceramics, and many plastics. This 2-part polyurethane resin offers exceptional physical protection and is designed for potting and encapsulating intricate electronic components and cable jointing boxes.

Black Flexible Urethane 8800 is a black, 2-part, flexible polyurethane resin. It has a low mixed viscosity and maintains excellent flexibility at low temperatures. In addition, this flexible urethane adheres strongly to a wide variety of substrates, including metals, composites, glass, ceramics, and many plastics. It is a cost-effective flexible potting option that provides exceptional physical protection and creates minimum stress on circuit boards and surface-mounted devices. It offers superior moisture resistance and is an ideal choice for harsh environments, especially saltwater exposure and marine applications.

UB-907FL is a two-component, industrial grade polyurethane adhesive system. Once cured, it forms a highly flexible bond line which provides peel and shear strength. It is deal for bonding a variety of metals, as well as plastics, glass, wood, and more. Can also be used for potting and encapsulating strain and heat sensitive electronic components.

Polytec PU 1000 is a one-component, room- temperature curing, highly flexible with excellent polyurethane-adhesive electrical conductivity. Polytec PU 1000 has been specifically developed for contacting chip modules on dual interface smart cards. It is used in micro electronics, hybrid and electronic applications. Polytec PU 1000 cures at room temperature or accelerated with heat. Polytec PU 1000 stands out due to its high flexibility combined with mechanical strength. It is also suitable for electrical contacting of copper surfaces The material can be applied by dispensing, jet-dispensing or manually.

Humiseal Urethane Adhesives Family are designed for demanding bonding requirements in industries including electronics, automotive, and health care devices among others. Polyurethanes are supplied as 2 component, chemical cure systems.

Diamond Tapes™ Polyurethane (PU) Foam Tape is coated with a medium strength acrylic adhesive which is scrim reinforced for stability. It is laminated to a silicone release paper liner. The tape has excellent flexibility which is suitable for thermal insulation & duct gasket purpose.

APPLI-TEC 0709 Urethane is a dark gray, thermally conductive, precision mixed, degassed, and frozen polyurethane adhesive compound for advanced electronic assembly. 0709 (Hacthane 121 B‐1) is HMS‐2353, Type IV certified. This thixotropic compound is suitable for electronic bonding, staking, and may be used as a filet as well. 0709 has a thermal conductivity of 0.9 W/mK, ideal for heat dissipation of components. 0709 cures to a tough and flexible material with low modulus and a very low Glass Transition Temperature (Tg). The cured material’s ability to not crack or harm bonded rigid components during thermal cycling provides a major advantage, as it will not compromise the integrity of the component. The CTE of 0709 is lower than conventional polyurethane elastomers, while retaining relatively low modulus. 0709 provides thermal conductivity and strain relief for many staking applications.
