Abstract:
A coating composition that is capable of absorbing UV or UV and visible light is disclosed. The coating composition includes a carrier and a pigment dispersed in the carrier. The pigment includes nanoparticles of a UV light absorber such that the coating composition is capable of absorbing UV light up to 360 nm or nanoparticles of a UV and visible light absorber such that the coating composition is capable of absorbing UV and visible light up to 550 nm, and the absorber includes an inorganic material.
Abstract:
A sulfur-crosslinkable adhesive composition of the non-aqueous type, that is to say not requiring the presence of water, usable for direct bonding of a pregelled polyester or vinyl ester composite to rubber in the uncured state. The composition comprises polyvinylpyridine-styrene-butadiene elastomer (“p-VSBR”) in combination with a polyester or vinyl ester resin. Preferably, the resin used is a novolak and/or bisphenol based resin of the epoxy vinyl ester type. This composition, unlike conventional RFL adhesives, does not require any activation treatment, such as intermediate drying, at the time of use. A process for preparing such an adhesive composition, use of said composition for the manufacture of laminated composite parts.
Abstract:
The present invention is concerned with the field of polymer chemistry and relates to rubber or elastomer compositions as can be used for vehicle tires, and to a method for the production of the rubber or elastomer compositions.The object of the invention is that in particular the elastic modulus of the compositions can be adapted depending on the temperature and/or the application conditions, and is a cost-effective and easily implemented method for the production of the compositions.The object is attained by rubber or elastomer compositions that contain at least one rubber or elastomer matrix and at least 20 to 150 phr of a phase change material in solid or liquid form. In the methods according to the invention, at least one rubber and at least 20 to 150 phr of a phase change material in solid or liquid form are used, the composition is mixed or the at least one rubber is at least brought into contact with the phase change material, and further processing steps can be performed and a vulcanization can be performed.
