EBECRYL® 170

EBECRYL® 170 is a chemical substance used as an acrylate modified acidic adhesion promoting agent. It's primarily employed as a modifier for ultraviolet (UV) and electron beam (EB) curable coatings on metals. Here's a breakdown of its key characteristics and applications:

Performance Highlights:

• Light color
• Low viscosity
• Acid functionality

Suggested Applications:

• Solder resist formulations
• Metal coatings

EBECRYL® 170 is soluble in various substances such as TPGDA, OTA 480, and TMPTA, with limited solubility in HDDA. It's typically used in formulations at concentrations ranging from 1% to 10% of the total formulation. Due to its acidic nature, precautions should be taken to protect formulations containing EBECRYL® 170 from humidity, and its use should be avoided with alkaline materials to prevent reactions.

Physical Properties:

• Density: 1.33 g/cm3
• Polymer solids: 100% by weight
• Höppler viscosity at 25°C: Approximately 3000 mPa.s
• Gardner color: Maximum 6
• Acid value: 270 - 330 mg KOH/g

Precautions:

• EBECRYL® 170 may have toxicological properties and can cause eye and skin irritation. Sensitization or allergic responses are also possible.
• It's important to consult the Safety Data Sheet for appropriate handling procedures and protective equipment.
• Storage should be done at temperatures below 40°C, and exposure to direct sunlight should be avoided to prevent uncontrollable polymerization.
• Contamination with acetone or other ketones can cause coloration of the product during storage.

Storage and Handling:

• Temperatures exceeding 40°C should be avoided for prolonged periods to prevent uncontrollable polymerization.
• Storage for more than 2 years is not recommended.
• Contamination with acetone or other ketones should be prevented to avoid coloration of the product.
