Abstract:
A plasticized binder composition suitable as a binder for chopped strand mats comprising (a) a copolymer obtainable by reacting; (i) 60-95 pphwm of vinyl acetate; and (ii) 5-40 pphwm of vinyl ester of α-substituted alkanoic acid; and b) a plasticizer, wherein the weight ratio of copolymer/plasticizer is from 1 to 6.
Abstract:
Disclosed are aqueous carpet-coating compositions suitable for use as binders or adhesives in carpet products. Such compositions, prior to being applied to carpet substrates and cured, comprise: A) a selected type of vinyl acetate/ethylene (VAE) copolymer dispersion which has been stabilized with emulsifiers and a cellulose ether-based protective colloid, and B) at least one carbon black based filler in the form of a dispersion/slurry with a solids content between 20 and 70%. These coating compositions exhibit especially desirable initial viscosity and viscosity stability characteristics. Carpet products which utilize such coating compositions to provide binder and/or adhesive layer within the carpet are also disclosed. Such carpet products can have desirable odor-controlling and odor-absorbing properties.
Abstract:
The invention relates to mineral wool fiber mats, which are stabilized by means of a binder made of polymers funtionalized with epoxy groups and/or with carboxyl groups and selected cross-linking agents. Said mats can be used as an insulating material and are characterized by low or no formaldehyde emissions.
Abstract:
Disclosed are carpet products comprising at least one flexible substrate and at least one coating and/or adhesive layer associated with the at least one flexible substrate. The coating and/or adhesive layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a selected ethylene content or glass transition temperature. It is also preferably substantially free of cross-linkable co-monomer moieties which generate formaldehyde upon curing and preferably has a particle size, dw, ranging from about 50 to about 500 nm. The carpet product is substantially free of polyvinyl chloride and bitumen and exhibits a Class B1 flame-retardancy in accordance with DIN 4102-14, corresponding to a critical heat flux of ≧about 4.5 kW/m2.
Abstract:
Disclosed is an aqueous formulation comprising a polymer which is based on a vinyl acetate copolymer, a binder system comprising said aqueous formulation and additionally an aqueous formulation comprising polymer (B). The invention further relates to a fibrous product comprising a fibrous substrate as well as the aqueous formulation or the binder system and use of the aqueous formulation or the binder system for coating synthetic or mineral fibres, for the manufacturing of Eternal Insulation Finishing Systems (EIFS), for increasing the alkali resistance of synthetic or mineral fibres and use in a process for the manufacturing of an alkali resistant glass fibre scrim. Further, the invention relates to a method for the manufacturing of the aqueous formulation.
