Omnistab UV B 75

Omnistab UV B 75 is a synergistic blend of 20% Omnistab AN 1135, 40% Omnistab UV 571 and 40% Omnistab LS 292. Acts as a light and heat stabilizer agent. It is an easy to pump, pourable liquid allowing dust free handling, automated dosage and shortening of mixing time. Exhibits resistance to exudation/ crystallization in many PUR systems. Prevents light and weather induced degradation of polyurethane products such as shoe soles, instrument and door panels, steering wheels, window encapsulations and head & arm rests. It can be easily added to aromatic or aliphatic polyurethane systems for thermoplastic moldings, semi-rigid integral foams, in-mold skinning and dope applications. Compatible with natural and pigmented materials. Particularly suitable for preparing light stable color pastes for the above-mentioned systems. Used in polyurethanes such as reaction injection molding (RIM) polyurethane and thermoplastic polyurethane (TPU). Use levels of Omnistab UV B 75 ranges between 0.2% and 1.5%, depending on the substrate and performance requirements of the final application.

In 2007 we decided to start ICG Specialty Chemicals selling specialty chemicals and additives under the tradename Omnistab.



Partners in Chemicals expanded its business in Middle East by setting up a branch office in Dubai in 2014.
