Abstract: A method of increasing the shear and tensile strength of spliced reinforcement panels used in roofing and waterproofing applications. The method is accomplished by facing and aligning at least two reinforcement panels in an end-to-end fashion on a roof deck in such a way that a seam is formed between the at least two reinforcement panels. A UV curable adhesive is then applied across the seam in a saw-tooth pattern and cured with a UV light source. The resultant spliced reinforcement panels will have a maximum load of approximately 34.4 to 48.8 lbf and a tensile strength of approximately 2.3 to 2.8%.

Abstract: A building material for roofing and the like has a UV curable top coating with a resin component and a photoinitiator component. The top coating may include pigments, such as those which increase reflectivity of the coating. The speed with which the coating can be cured permits use in a roofing material assembly line without slowing the feed rate and eliminates energy intensive drying procedures.

Abstract: A method for splicing reinforcement panels using a UV curable adhesive. The method includes the steps of: (a) aligning facing ends of two reinforcement panels; (b) applying adhesive on said facing ends of said two reinforcement panels; (c) butting together said facing ends of said two reinforcement panels; and (d) applying an ultraviolet light source to the adhesive. The method eliminates waste, reduces splicing time and improves the mechanical properties of the resultant mat.

Abstract: The present invention is directed to a fire retardant composition, comprising: a primer solution; expandable graphite particles; triethyl phosphate; and aluminum trihydrate, wherein the triethyl phosphate comprises from about 1 wt. % to about 15 wt. % based on the weight of the composition.
