Physical and chemical properties

Use

U-CAT 5003 is a quaternary phosphonium bromide catalyst used for curing epoxy resins. It is a fast curing accelerator with a good application period and excellent physical properties such as transparency, toughness and thermal stability. U-CAT 5003 is particularly suitable for transparent applications, such as LED packaging.

Pros

· Fast curing

· Good application period

· Excellent physical properties

· Suitable for transparent applications

Precautions

U-CAT 5003 is a hazardous material and should be handled with care. It is a skin and eye irritant and can cause respiratory problems. It should be stored in a cool, dry place and kept out of reach of children.

If U-CAT 5003 comes into contact with skin or eyes, wash the affected area immediately with soap and water. If inhaled, remove the person to fresh air and seek medical attention. If swallowed, do not attempt to induce vomiting. Call poison control or seek medical attention immediately.

In addition to the above, here is some additional information about U-CAT 5003:

· It is a clear liquid with a faint odor.

· It is not flammable.

· It is compatible with most epoxy resins.

· It is usually used in concentrations of 0.5-1% by weight.

U-CAT 5003 is an important tool for formulating high performance epoxy resin systems. It has fast curing, good service life and excellent physical properties. It is especially suitable for transparent applications, such as LED packaging.
