Patent number: 8378017Abstract: The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.Type: GrantFiled: December 14, 2006Date of Patent: February 19, 2013Assignee: Designer Molecules, Inc.Inventors: Stephen M.

Patent number: 8349068Abstract: A premixed composition is formed from modified polyacrylate polymer, silicone emulsion, and silane, that cures rapidly to form a composition that can be used as a grout or coating. The premixed composition includes a latex resin including an acrylic-based polymer, a silicone emulsion, and a silane, and optionally may include various fillers, pigments, and adjuvants. These components in the proper proportions form a stable viscous suspension that can be floated into tile joints, and cleaned from an adjacent tile surface. The composition rapidly cures to form a hard mass that is resistant to abrasion, in both dry and wet conditions, is color consistent, and is resistant to staining.Type: GrantFiled: January 28, 2010Date of Patent: January 8, 2013Assignee: Custom Building Products, Inc.Inventors: Steven L. Taylor, Zosimo D. Pamaran
