The Dabco® DC and LK products from EVONIK are silicone-free and silicone-based stabilizers for polyurethane (PUR) and polyisocyanurate (PIR) systems.
Silicone based surfactants support the emulsification of the A-component, regulate the nucleation and stabilize the cells in the foam.
Silicone-free surfactants are organic tensides for microcellular and rigid foam formulations which provide a smooth surface and excellent adhesion.
Choosing the right surfactant significantly affects the physical properties of the foam. This includes emission reduction, insulating property improvements (lambda values), achievement of the desired cell structure as well as an increased flame resistance.
The additives are used in soft block foams and spray foams as well as insulation panels and shoe soles. In non-cellular applications, the surfactants are used in the field of adhesives, sealants, elastomers and casting resins.
In addition to the stabilizers, we also offer catalysts.
