PARSEAL 7011 is a low viscosity sealant specifically formulated for impregnation of porosity of metal castings, powdered metal parts and ceramics. The liquid sealant undergoes free radical polymerization to form a tough thermoset polymer that permanently seals the pores. Liquid sealant can be easily removed with plain water.

Advantages

• Fluorescence under blue light. Inspection of impregnated parts performed under blue light.
• Excellent resistance to coolants, lubricants, fuels, hydraulic fluids, air, glycols and industrial solvents.
• High performance sealant cures at room temperature.
• Meets military specification Mil-I-17563 Rev.C-Class 1

Application

• Ideal for automotive powertrains, steering systems, air conditioning and other components.
• Wide variety of applications in military, aerospace, general industry, electronics and telecommunication industry.
• Plating and coating of metal parts.

Impregnation Process:

• Resin Activation: - Liquid resin is loaded into impregnation tank aerated and cooled at 2-3 °C; adding catalyst at level of 5-10 g/100 liters makes activation. This quantity is normally sufficient to have curing time of 16-25 minutes measured in probe glass tube at 45 °C. This test should be the standard reference for bath stability conditions and will assure room temperature anaerobic curing of about 3 hours into metal porosity. In case of bath contamination from active metals, such as brass and copper, test time needs to be shortened; retarder solution may be added to restore correct time.
• Metal parts are loaded into a basket and lowered into resin tank.
• Vacuum of about 20 mill bars is applied for 3-5 minutes.
• Air restored to tank, basket is extracted from bath and centrifuged to remove excess of liquid sealant.
• Basket is transferred to wash tank charged with water or water-detergent solution.
• Curing is normally performed at room temperature. In some cases is heated at higher temperature to increase the curing speed. 

Handling and Storage: Store in a cool place, avoid exposure to direct sunlight and heat. Air space in container keeps product liquid, the absence of oxygen may lead to premature polymerization with large heat generation. Product is classified as irritant. Avoid contact with skin and eyes, refer to MSDS before use.

PRECAUTIONS: This product and the auxiliary materials normally combined with it are capable of producing adverse health effects ranging from minor skin irritation to serious systemic effects. None of these materials should be used, stored, or transported until the handling precautions and recommendations as stated in the Material Safety Data Sheets (MSDS) for this and all other products being used are understood by all persons who will work with the.

Parson makes no other warranty, either express or implied, including those regarding such other information, the data upon which the same is based, or the results to be obtained from the use thereof; that any product shall be merchantable or fit for any particular purpose; or that the use of such other information or product will nor infringe any patent.

PARSEAL 7090 is a low viscosity sealant specifically formulated for impregnation under vacuum of porosity of metals castings, powdered metal parts, wood and ceramics. The liquid sealant undergoes free radical polymerization to form a tough thermoset polymer that permanently seals the pores. This product cures in 5 -15 minutes at temperature of 75 - 90°C.

Advantages

• Fluorescence under blue light. Inspection of impregnated parts performed under blue light.
• Excellent resistance to coolants, lubricants, fuels, hydraulic fluids, air, glycols and industrial solvents.
• High performance sealant for low to medium production capacity with minimum maintenance.
• Meets military specification Mil-I-17563 Rev.C-Class 1

Application

• Ideal for automotive powertrains, steering systems, air conditioning and other components.
• Wide variety of applications in military, aerospace, general industry, electronics and telecommunication industry.
• Plating and coating of metal parts.

• Liquid resin is loaded into impregnation tank aerated and cooled at 2-3 °C; adding catalyst at level of 5-10 g/100 liters makes activation.This quantity is normally sufficient to have curing time of 5 – 15 minutes measured in probe glass tube at 75 °C.

PARSEAL 7091 is a low viscosity reactive sealant specifically formulated for impregnation under vacuum of porosity of metals castings, powdered metal parts, wood and ceramics. The liquid sealant undergoes free radical polymerization to form a tough thermoset polymer that permanently seals the pores. This product cures in 5- 15 minutes at temperature of 90 0C.

Advantages

• Excellent resistance to coolants, lubricants, fuels, hydraulic fluids, air, glycols and industrial solvents.
• This resin technology greatly reduces the consumption of the impregnation resin and will minimize the output of wastewater from the process.
• Meets military specification Mil-I-17563 Rev.C-Class 1

Application

• Ideal for automotive powertrains, steering systems, air conditioning and other components.
• Wide variety of applications in military, aerospace, general industry, electronics and telecommunication industry.
• Plating and coating of metal parts.

Impregnation Process:

• Impregnation by immersion of parts in the resin 7091 under vacuum.
• Cleaning of parts: the residual resin being removed from the surface by a water washing solution containing the additive 7091 W/A at level of 12% w/w. A further cleaning by pure water will improve the surface quality of the parts. The resultant water will be feed together with further additive 7091 W/A to restore the level of the washing bath.
• Recovery of resin 7091 from the washing solution: the resin will be separated and collected at the surface of the washing bath after rest time, than recycled at the impregnation step.
• Curing of impregnated parts by immersion in hot water bath typically at 90°C per 5 - 15 minutes.
