  • Patent number: 9920199
    Abstract: An improved silane modified polymer useful in adhesive compositions is made from a silane precursor material made by a process comprising reacting an organic compound having a backbone that is terminated by an amino group having at least one active amino hydrogen and a hydrolysable silane, wherein the backbone is comprised of at least one secondary amino group having one active amino hydrogen and a Michael addition acceptor compound, wherein the Michael addition compound fails to have a group reactive with an isocyanate group to form the silane precursor compound.

  • Patent number: 9832902
    Abstract: Electrical circuit assemblies flood coated with polymeric flood coat compositions as described or exemplified herein are provided. The flood coat composition is characterized as having a sufficient gel time and thixotropic index as to substantially cover or encapsulate the electrical circuit assembly as a fixed mass upon cure such that the thickness of the polymeric coating on surfaces horizontal to the assembly is from 20 mils to 75 mils, and the thickness on surfaces vertical to the assembly is from 4 mils to 20 mils. Such flood coated assemblies and devices containing same are advantageous over conventional potting materials or conformal coatings because they require less material thereby reducing weight and cost, and they are able to withstand extreme environmental stresses such as from temperature and/or vibrations.
