Patent number: 11285709Abstract: Disclosed herein are various embodiments of a protective packaging system suitable for use with a prefinished building article. The protective packaging system generally is designed to reduce shrink back of the flexible substrate after tension is applied. The protective packaging system generally comprises at least one outer layer, at least one core layer and at least one adhesive layer. One or more layers of the protective packaging system may include a roughening agent such that the flexible substrate will not “gloss” or burnish a coating on a prefinished building article. The protective packaging system may also include one or more biocides.Type: GrantFiled: May 15, 2020Date of Patent: March 29, 2022Assignee: James Hardie Technology LimitedInventors: Yongjun Chen, Caidian Luo, Jimmy Lee McCammon

Publication number: 20210371338Abstract: Integrally waterproof fiber cement composite materials including interior and exterior fiber cement articles for building structures are disclosed. Fiber cement formulations include small percentages of silica fume and silanol. Formulations may additionally include a cementitious binder, silica, and a density modifier such as calcium silicate or perlite. Advantageously, the addition of preselected small percentages of silica fume and silanol has been discovered to yield waterproofness at substantially lower concentrations of silica fume and silanol than would be required to yield waterproofness when using either silica fume or silanol alone.Type: ApplicationFiled: November 6, 2019Publication date: December 2, 2021Inventors: Noel Dones, Basil Naji, Caidian Luo

Patent number: 8906500Abstract: An engineered composite building material, such as fiber cement, having one or more engineered sub-surface regions designed to provide the building material with improved moisture ingress resistance, paint adhesion, and other mechanical properties is provided. The sub-surface region has a cement-polymer matrix formed by introducing an impregnating agent into the pores of the substrate. The composite building material may be formed by applying impregnating agents to the subsurface regions of the substrate to form chemical and/or mechanical bonds with the matrix of the building material, the reinforcement fibers, and/or the surface coatings applied to the material. The thickness of the sub-surface regions may be controlled by varying the viscosity and porosity of the building material substrate. The cement-polymer building material has enhanced durability, weather resistance, strength, and stiffness.Type: GrantFiled: March 7, 2013Date of Patent: December 9, 2014Assignee: James Hardie Technology LimitedInventors: Weiling Peng, Hong Chen, Caidian Luo, Donald J.
