Polyurethane Resin

The range of polyurethane resins can be divided into four groups

The Standard range is the starting point for most applications with the polyether/polyester chemistry allowing variations in processing properties (viscosity, pot life etc) and the cured properties (hardness, flammability, adhesion etc). The applications include PCB potting, cable jointing, transformer encapsulation and applications requiring (UL V-0 rated) for switches, sensors and encapsulation.

The Water Resistant Resins are produced from uniquely hydrophobic polyols and are formulated to add, for instance, flame retardancy. All the products in the range retain flexibility down to ?40°C and have excellent electrical properties including low dielectric loss.

The Re-enterable Range can be clear and unfilled or filled and flame retardant. They are easily removed from delicate components, and have excellent thermal cycling properties, placing no stress on components at extreme low temperatures whilst protecting the electronics from damaging moisture etc. Applications included clam-shell cable jointing, control panel displays and sealing outdoor enclosures.
