PETIA

• PETIA is a multifunctional reactive diluent with a high degree of acrylic unsaturation and finds use in a variety of ultraviolet light (UV) and electron beam (EB) curable coatings and ink systems where a high degree of crosslinking is desired.
• PETIA is a mixture of predominantly the tri- and tetra-acrylate esters of pentaerythritol.
• PETIA has a higher ratio of tri - to tetra-acrylate ester than the similar product EBECRYL 180, and therefore remains liquid at normal ambient temperatures.

PETIA is characterized by:

• High acrylate functionality
• Residual hydroxyl content
• Very low vapor pressure
• Liquid at 25°C

UV/EB curable formulated products containing PETIA are characterized by:

• Rapid photo response
• High cross-link density
• Excellent hardness
• Excellent chemical resistance

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as oligomers, additives and photoinitiators.

• PETIA finds application in UV/EB cured coatings and ink systems.
• PETIA is an especially useful diluent where fast cure speed, hardness and high gloss properties are required.

• Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids.
• This might cause uncontrollable polymerization of the product with the generation of heat.
• Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers.
• Procedures that remove or displace oxygen from the material should be avoided.
• Do not store this material under an oxygen free atmosphere.
• Dry air is recommended to displace material removed from the container.
• Wash thoroughly after handling. Keep container tightly closed.
• Use with adequate ventilation.
• PETIA may crystallize if exposed to low temperatures, particularly in temperatures below 4°C.
• Crystallized PETIA may be safely melted by placing the container in a controlled temperature water bath or heated room, no warmer than 120°F (49°C), for a period of 24 hours or less. Steam or electrical heating systems, which generate localized hot spots, should never be used to melt this product.
• Material being melted in 55-gallon drums should be agitated at regular intervals to assure redistribution of polymerization inhibitor and oxygen.
