The flat roof structure further comprises a water reducing layer below the water attenuation layer, and at least one drainage point in fluid communication with the water attenuation layer and arranged to direct water from the flat roof structure towards the ground. The binder is an aqueous composition free of phenol and formaldehyde comprising:



a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 2.0 mmol/g, based on the dry weight of the lignosulfonate lignins,

Abstract: Binder compositions for fiberglass are disclosed, comprising a polycarboxylic acid such as polyacrylic acid and a crosslinking agent. The crosslinking agent comprises a polyhydroxy component formed from a reaction of an epoxidized plant oil with an amine and optionally with a phenolic compound. The molar ratio of the amine to the epoxidized plant oil at the beginning of said reaction may be greater than 1:1. Methods of making the binders and fiber-containing composites made with said binders are also described.

Abstract: Embodiments of the present technology may include a method of reducing leaching from a fiber-containing composite. The method may include forming an aqueous dispersion of fibers. The method may further include applying a binder composition to the aqueous dispersion of fibers to form a binder-fiber mixture. The binder composition may include a carbohydrate, a nitrogen-containing compound, and a catalyst that catalyzes the reaction between the carbohydrate and the nitrogen-containing compound. The catalyst may be water soluble before curing but water insoluble after curing. In addition, the method may include curing the binder-fiber mixture to form the fiber-containing composite.

Abstract: An air-laid blank (10) comprises natural fibers at a concentration of at least 70% by weight of the air-laid blank (10) and a thermoplastic polymer binder at a concentration selected within an interval of from 2.5 up to 30% by weight of the air-laid blank (10). The air-laid blank (10) has an average density and a portion (11) of the air-laid blank (10) has a density different from the average density. The air-laid blank (10) is produced by modifying the air-permeability of a portion (121) of an air-permeable collector (120) to form a portion (11) of the air-laid blank (10) having a density from the average density. The air-laid blank (10) has two parallel planar major surfaces (12, 14)
