DB 75 is liquid heat and light stabilizer system designed for polyurethanes
DB 75 is used in polyurethanes such as Reaction Injection Molding (RIM) polyurethane and thermoplastic polyurethane (TPU). The blend can also be used in sealant and adhesive applications, in polyurethane coating on tarpaulin and flooring as well as in synthetic leather.
DB 75 prevents the processing, light and weather induced degradation
of polyurethane products such as shoe soles, instrument and door panels, steering wheels, window encapsulations, head and arm rests.
DB 75 can be easily added to aromatic or aliphatic polyurethane systems for thermoplastic moldings, semi-rigid integral foams, in-mold skinning, dope applications. It can be used with natural and pigmented materials. DB 75 is particularly suitable for preparing light stable color pastes for the above mentioned systems.
easy to pump, pourable liquid allowing dust free handling, automated dosage and shortening of mixing time
all liquid package; no sedimentation of additives in the polyol phase even at low temperatures
resistant to exudation/crystallization in many PUR systems
Product forms Clear, slightly yellow liquid
Guidelines for use
The use levels of DB 75 range between 0.2 % and 1.5 %, depending on the substrate and performance requirements of the final application:
Reactive two-component integral foams 0.6 % – 1.5 %
Adhesives 0.5 % – 1.0 %
Sealants 0.2 % – 0.5 %
Extensive performance data of DB 75 are available for many applications.
