Arathane 5753 A/B Kit

Urethane Casting Compound

Arathane 5753-A/B (LV) is a translucent, amber, two-component polyurethane casting compound which, when cured, provides excellent electrical insulation to electrical/electronic parts.

Arathane 5753-A/B (LV) exhibits excellent reversion resistance under heat and high humidity conditions. As a cured system, this material meets NASA outgassing properties critical for applications in outer space and high vacuum environments.

Arathane 5753-A/B (LV) is typically recommended for encapsulating coils, trimpots, potentiometers and modules with complicated circuitry and/or stress sensitive components.

Packaging & Storage

Arathane 5753-A/B (LV) is moisture sensitive and should be stored in a dry place and, whenever possible, in the tightly closed original containers at 25°- 40°C. Under these conditions, shelf life will be 6 months from the date of shipping. Partial containers should be resealed using dry nitrogen or argon. Contact Customer Service for packaging information.

System Preparation

Exposure of Part A to low temperatures for prolonged periods may cause crystallization. Part A must be reliquified by heating to 70°C (158°F). Heat Part A until clear amber solution is achieved. Remove container from oven. Do not disturb contents. Allow material to cool to 25°-40°C in a controlled environment; do not force cool.

Measure height of the precipitate from outside of bottle. Do not use if level of precipitate is above 3/8 inches (0.6 cm), or if liquid remains cloudy or contains gelled particles. Contact our Customer Service Department with lot number, date received and condition of bottle.

Material is ready for use if level of precipitate is below 3/8 inches. Do not agitate. Slowly decant clear resin out of the bottle without disturbing the precipitate. Enough material has been packaged to allow for any precipitate and to assure sufficient Part A. For best results, filter Part A through nylon tricot, 10-25 micron size.

Use entire bottle so remaining material will not be contaminated with moisture. If this is not possible, any remaining material must be will blanketed with dry nitrogen or argon and the cap tightened securely. Store at 25°-40°C for best long-term stability.

Mixing

Container should be plastic, glass, or metal. Paper and wooden containers or utensils are not recommended because of high moisture content. Weigh Part B into container first. Add Part A to container. (Do not use Part A if precipitate level is greater than 3/8 inches.)

Slow machine mixing or hand stirring will minimize air entrapment. Complete and thorough mixing of Parts A and B is essential for optimum end properties.

Mixture may be vacuumed by drawing 29-29.5 inches of Hg for 2-3 minutes. Material will rise and "break" so allow enough room for expansion inside the container.

Handling/Safety Precautions

Mandatory and recommended industrial hygiene procedures should be followed whenever our products are being handled and processed. For additional information please consult the corresponding material safety data sheets.

Work in a well-ventilated area and use clean, dry tools for mixing and applying. For two component systems, combine the resin and hardener according to mix ratio. Mix together thoroughly and use immediately after mixing. Material temperature should not be below 65°F (18°C) when mixing.

First Aid

Skin: Immediately wash with soap and water. Remove contaminated clothing and launder before reuse. Discard contaminated shoes.

Eyes: Immediately flush with water for at least 15 minutes. Call a physician.

Ingestion: If conscious, give plenty of water to drink. Do not induce vomiting. Call a physician. Inhalation: Remove person to fresh air. Administer oxygen or artificial respiration if necessary. Call a physician.

Other: Referral to physician is recommended if there is any question about the seriousness of an injury
