Abstract: Two component resin system consisting of a first component A and a second component B characterized in that component A comprises: a. a compound capable of undergoing a radical copolymerization selected from the group consisting of unsaturated polyester resins, vinyl ester resins and mixtures thereof, b. an epoxide functional resin as compound capable of reacting with an aliphatic amine and in that component B comprises a mixture of c. an aliphatic amine d. a perester.

Abstract: 1,6,9,14-Tetrasubstituted terrylenetetracarboxylic diimides are particularly useful for absorbing and emitting in the long-wavelength red and near infrared region of the electromagnetic spectrum.

Abstract: Thermally curate resin composition, having shrink-controlled properties and being suitable for use in sheet moulding compounds and bulk moulding compounds (SMCs and BMCs) comprising, inter alia (a) an unsaturated polyester; (b) an alkenyl aromatic monomer; (c) a low profile additive; (d) a peroxide initiator; (e) a thickening agent; (f) fibrous reinforcement material; and optionally one or more components selected from the group of (g) mould release agents; (h) wetting and viscosity reducing agents; and (i) fillers, wherein the composition also comprises a uret dione diisocyanate, in an amount of at least 0.2-1.0% by weight relative to the total weight of components (a), (b) and (c) of the resin composition. The resin compositions according to the invention in particular have a low emission of volatile organic compounds (VOC). More particularly, the resin compositions have excellent Class A properties.
