Patent number: 6399155Abstract: This invention relates to novel airbag coating compositions and systems comprising heat-expandable microspheres that provide effective insulation for the target airbag fabric during exothermic inflation. The inventive airbag fabrics are either pre-calendered prior to application of this composition or are coated through a floating knife method with such heat-expandable microsphere-containing compositions. The coated airbag fabrics and cushions may then be heated to expand the microsphere constituents of the coating compositions both within the interstices between the individual yarns of the fabric and over the raised yarns of the fabric. Such a coating system thus provides an extremely high degree of protection from heat exposure that permits structural integrity of the target airbag cushion airbag and provides protection from such high inflation temperatures to a vehicle passenger cushion during such a highly exothermic inflation event.Type: GrantFiled: April 6, 2001Date of Patent: June 4, 2002Assignee: Milliken & CompanyInventors: Andrew D. Child, Derek S. Kozlowski

Patent number: 6395331Abstract: A process is described for applying a thin-film, hydrophobic, oil-repellant, stain-resistant, optical coating to a transparent substrate. The coating is applied using a treatment solution that incorporates an organosilane in a solvent of water, alcohol, and ethylene glycol or glycerol, and an acid catalyst, with the organosilane having a preferred concentration in the range of 0.05 to 50 mmole per liter. The treatment solution preferably is prepared in a two-step procedure, in which the organosilane is first reacted in concentrated form and then diluted. After the treatment solution has been applied to the transparent substrate, e.g., by dip coating, the coated substrate is dried, preferably by flash-drying at room temperature and then heating it to a prescribed elevated temperature, in a prescribed humidity.Type: GrantFiled: April 10, 2000Date of Patent: May 28, 2002Assignee: Yazaki CorporationInventors: Yongan Yan, Din-Guo Chen

Patent number: 6364993Abstract: A laminate and a method for making a laminate having a hidden or shielded image. The laminate includes a substrate having an first surface containing an image thereon and a polymeric film laminated to the first substrate surface overlying the image. The film contains an exposed water activatable opaque layer having a thickness ranging from about 0.60 mil to about 2.0 mil, the opaque layer including aluminum silicate and a binder. Upon wetting the opaque layer, the hidden or shielded image is revealed. The method includes a means for producing the laminate in high volumes for minimizing the production costs thereof. Upon drying the opaque layer, the image is again hidden or shielded from view. The laminate may be used multiple times without adversely affecting its ability to reveal and hide images.Type: GrantFiled: September 1, 1999Date of Patent: April 2, 2002Inventors: Bryan A. Netsch, Mark H. Bailey
