Original Press Release:
New Environmentally-Friendly Polyurethane Potting Compound
Cranston, RI – Epoxies, Etc., a leading manufacturer of adhesive products, has released a new plant-based potting, casting and encapsulating compound for electronic applications with low toxicity requirements.
Called 20-2121 Polyurethane, this environmentally-friendly alternative to conventional potting compounds is made from natural oil polyol instead of fossil fuel feedstocks. As a low toxicity product, 20-2121 meets FDA food contact requirements and contains no TDI, MbOCA or Mercury.
Other properties include:
Little shrinkage or exotherm.
Alleviation of mechanical and thermal stresses on sensitive electrical components.
Limited stress on electronics with good elastomeric properties.
The 20–2121 compound stacks up well against traditional urethane potting compounds with a tensile strength of 2,000 psi and a tear strength of 119 PLI. It has a mixed viscosity of 2,000 cps at 25°C and a gel time of 20 minutes at 60°C.
Samples of 20-2121 polyurethane are available at: http://www.epoxies.com/try-adhesives.aspx
