APPLICATIONS

1. The product is suited for fabricating moulds of figures, art objects, furniture, and similar items.

2. This product can be used in part fabrication.

3. Potting in electrical/electronic assemblies/devices, imparting water repellant and insulation coating.

4. Part encapsulant of motor, automotives, mechanical and chemical equipment.

5. Sealant in building.

6. Other potential applications.


HOW TO USE

1. Mixing Part A and Part B in a reasonable ratio, mixing completely until uniform.

2. Suggested use level: The ratio of Curing agent/Base is 2~5%. It should be noted that increasing the ratio of curing agent will hasten the rate of curing.

3. For DY-OH201, the curing typically requires about 40 minutes when curing agent ratio is 5%.

4. For DY-OH202, the curing typically requires 3~5 hours when curing agent ratio is 5%.

5. It is recommended that the two parts be combined using process equipment that will not introduce air contamination. If air bubbles are entrapped during mixing, the mixture must be degassed under vacuum. Introduction of air into the system will result in lowering the physical properties of the cured rubber.


PRODUCT SAFETY INFORMATION

1. Care should be taken to minimize air entrapment.

2. When the A and B parts are mixed, the mixture must be used at once and should not be re-mixed with silicone rubber again in case curing failure.

3. The final mechanical properties of the mold will be reached within 4 days.

4. Precautions must be taken to prevent moisture from contacting these materials.

5. When used in electrical potting, the mixture may de-polymerize when exposed to temperatures above 150℃ over a period of time or when totally confined in storage at high ambient temperatures.
