ALH Systems Clear Polyurethane Resin

<P>A two-component polyurethane potting compound that is totally transparent to normal light and forms an excellent water-resistant barrier around encapsulated components. Specially designed divided cartridges and syringes, with disposable mixing nozzles, provide freshly mixed, accurately placed compound.</P><P>Each 250ml cartridge (1x 87-7172) has 2 compartments inside that keep the resin and hardener separated. When the cartridge is compressed in a caulking gun, both resin and hardener are emitted in the correct proportion. Inside the mixing nozzle (87-7174) is a matrix of tubes that mix the resin with the hardener as it progresses, exiting the nozzle completely mixed.</P><P>One 250ml cartridge produces 250ml of mixed resin and hardener, ready for use. If not all the 250ml is used at once, a new mixing nozzle (87-7174, available separately) will be required.</P><P>For smaller amounts of ready-mixed resin, we recommend the smaller 50ml dual syringe (87-7176 plus nozzle 87-7178). </P>
