8 ADDITIVES Enhancing the aesthetics, improving performance and protection REPI liquid additives for polyurethanes are often used to enhance the aesthetical characteristics, especially covering possible inhomogeneities of the material. Additives are as well used as performance and protection aids, for example to improve heat resistance, to reduce oxidation and to protect from aging - all of which are crucial in maintaining the PU physical properties. UV STABILISERS REPI UV STABILISERS are special liquid blends of UV absorbers and anti-oxidants developed to improve UV and heat resistance in PU applications like flexible foam, rigid foam and C.A.S.E. for use in Automotive and Transportation, Furniture and Bedding, Footwear, Building and Constuction, Marine and Offshore industries. REPI UV STABILISER are particularly recommended for light colour shades. They can be used as a component in the polyol formulation or can be fed in a separate stream directly into the mixing head. benefits Strong effectiveness in UV absorption Excellent thermal stability Optimal chemical stability Compatible with polyether and polyester PU systems Easy blending with polyol Can be blended with REPI colours and additives Environment and Legislation Reach and VDA compliance Low fogging Low VOC emissions REPI UV STABILISERS Effectiveness in UV Absorption Absorbance 1,,9,8,7,6,,4,3,2,1, Typical Properties Appearance: liquid Colour: neutral to pale yellow Density: g/cm 3 at C ph value: 7-8 Water Content: <,3%, Karl Fischer Reactive groups: none Shelf life: 12 months in sealed container dosing Suitable for standard liquid dosing units LDR: 1-3% on PU systems packaging Standard packaging include 2, and Kg. drums besides 1 ton bulk IBC.

9 Antiscorching Agents White Foam Stabilisers To protect neutral polyurethane flexible foam from photo degradation, oxidation and discoloration, our R&D specialists propose REPI WHITE FOAM STABILISERS that delay the effects caused by UV radiation and provide additional anti yellowing effect. With REPI WHITE FOAM STABILISERS, neutral PU flexible foams will become whiter and brighter, thus gaining the appeal of a premium foam. They can be used as a component in the polyol formulation or can be fed in a separate stream directly into the mixing head. An even brighter effect can be obtained by combining these REPI WFS with REPI OPTICAL BRIGHTENERS. benefits Strong UV light absorption Excellent anti-yellowing action Optimal anti-oxidant Compatible with polyether and polyester PU systems Easy blending with polyol Can be blended with REPI additives Typical Properties Appearance: liquid Colour: white Viscosity: 1. to. cp Density: 1,3 to 1, g/cm 3 at C Water Content: <,%, Karl Fischer Shelf life: 12 months in sealed container dosing Suitable for standard liquid dosing units LDR: 1 - % on PU systems packaging Standard packaging include 2, and Kg. drums besides 1 ton bulk IBC.
