STRUKSILON 8002

Application Fields

STRUKSILON 8002 is used as a silicone surfactant for production of polyurethane rigid foam. It is especially recommended for the use in PU 1- or 2-component spray foam applications.

Chemical and Physical Properties

According to its chemical structure STRUKSILON 8002 is a polyether-modified polydimethyl siloxane resistant to hydrolysis. Due to the negligible content of hydroxyl or other groups reactive towards isocyanates it is chemically inert in polyurethane formulations.

STRUKSILON 8002 is a clear, colourless to slightly yellow liquid of middle viscosity, has strong surfactant properties and is miscible with water at room temperature.

General chemical structure:

Typical Properties:

Viscosity at 25°C	[mPas]	950
Turbidity point	[°C]	35
Density at 25°C	[kg/m³]	app.1.03
Flash point (DIN/ISO 2562)	[°C]	>100
Refractive Index at 25°C		1.449

Technical Properties

Due to its chemical structure STRUKSILON 8002 can be incorporated in A as well as in B-components.

STRUKSILON 8002 is compatible with isocyanate. STRUKSILON 8002 can be mixed without problems with the polyols commonly used in the formulation of PU 1- or 2-component spray foam.

STRUKSILON 8002 is well suited for most of the common blowing agents like Propane/Butane, 134 a , 152 and dimethylether. STRUKSILON 8002's high activity results in high foam yields combined with excellent foam structures.

STRUKSILON 8002 can also be used in the majority of gun foam applications. As it might fail in some gun foam formulations it is recommend to check foam structure and shrinkage carefully before applying

STRUKSILON 8002 in gun foam.

Recommended Dosage

Usually, STRUKSILON 8002 is applied in quantities of 0.5 to 1.5 php (parts on 100 parts polyol). We recommend to adjust the optimum dosage to the corresponding formula. However, a concentration of 3 php should not be exceeded.

Product Safety and Handling

STRUKSILON 8002 is not a hazardous material for the purposes of hazardous materials regulation.

STRUKSILON 8002 does not contain aminic components.

Further information regarding safety, toxicology, special properties of the product, transport and storage are given in the safety data sheet.
