ARATHANE® CY 11035-1 / ARATHANE® HY 11036

• Low viscosity and good impregnation capability
• Solvent free and free of foaming agent
• Long pot-life, low exotherm, suited for large bushings
• Permanent elastic, mechanically strong, good adhesion
• Temperature range -60 °C to 120 °C
• Low dielectric losses
• No filler, no sedimentation
• Cures at 8 °C
• Low water absorption

Preparation of parts

• The parts, which are to be casted, should be dry, clean and free of greases.

• Preheating is not necessary, best temperature range for processing is between 18 and 40 °C, it also works at temperatures down to 8°C.

Mixing and Injection

• Polyol and Isocyanate are mixed according to the specified mix ratio using preferably a two component metering and mixing machine.

• High speed mixing head is preferred.
• The foaming gas is injected during mixing at elevated pressure.
• Molds to be filled preferably from the bottom side. Heights of several meters are possible.

Note:

• CY 11035 /HY 11036 is the precursor of the actual system, based on ARATHANE® CY 11035-1 / ARATHANE® HY 11036
• The technical difference is not significant.
• One component of Polyol CY 11035 was no more available, a slight change to CY 11035-1 could not be avoided.

Processing methods: Casting with gas injection

• ARATHANE® CY 11035-1 180KG Q4E
• ARATHANE® HY 11036 25KG Q4E 

• Store the components in a dry place according to the storage conditions stated on the label in tightly sealed original containers.
• Under these conditions, the shelf life will correspond to the expiry date stated on the label.
• After this date, the product may be processed only after reanalysis.
• Partly emptied containers should be tightly closed immediately after use.
• ARATHANE® HY 5610 must be protected from moisture. Storage tanks should be blanketed with dry air or nitrogen.
• Storage at temperatures above 50°C is not recommended, since this can lead to the formation of insoluble solids and also the viscosity build-up increases on extended storage. Storage at low temperature is not recommended because it may lead to some crystallization.
• Crystallized material must be melted out immediately by short time heating.
• For information on waste disposal and hazardous products of decomposition in the event of a fire, refer to the Material Safety Data Sheets (MSDS) for these particular products.
