Q. Can I solder to Silver Conductive Epoxy?
A. No, Silver Conductive Epoxy has the temperature constraints of an epoxy and cannot be soldered to. Soldering to this product will cause it to melt.

Q. My 8331 product has a small discoloration. Is this a problem?
A. The discoloration is not a problem and will not affect the adhesive nor the conductive properties.

Physical and Chemical Properties

Physical State: Liquid Odor: Slightly aromatic Solubility: None Evaporation Rate: N/e
Boiling Point: N/e Specific Gravity: 2.47 Vapor Pressure: N/e Vapor Density: >1 (Air=1) pH: N/a


Hazards Identification

WHMIS Codes: B3, D2B

NFPA Ratings: Health 2 | Flammability 1 | Reactivity 0

HMIS Ratings: Health 2 | Flammability 1 | Reactivity 0

Eyes: Causes irritation.

Skin: Prolonged exposure may cause skin irritation. May cause allergic reaction in some individuals.

Inhalation: At room temperature, exposure to vapors is unlikely due to physical property of low volatility. Higher temperatures may generate vapor levels sufficient to cause irritation to the respiratory tract (nose, throat, and lungs).

Ingestion: Single dose oral toxicity is low. Amounts ingested incidental to industrial handling are not likely to cause injury; however, ingestion of large amounts may be harmful.

Chronic: Chronic inhalation or ingestion of silver salts may cause argyria characterized by a permanent blue-gray discoloration of the eyes, skin, mucous membranes, and internal organs. Inhalation and/or of fumes may cause metal fume fever, which is characterized by flu-like symptoms with metallic taste, fever, chills, cough, weakness, chest pain, muscle pain and increased white blood cell count
