Product Usage

PT303 is a strong foaming low-odor tertiary amine catalyst. Its performance is similar to that of 5, but the odor is much lower than that of 5. It can strongly catalyze urea (water —Isocyanate) reaction;

PT303 can be used for different types of rigid foam, especially rigid spray foam;

The dosage of PT303 can be adjusted according to the formula, actual application and requirements;

PT303 can be used in combination with PT302 and PT304 in spray foam.

Introduction:

PT303 catalyst is a high-efficiency polyurethane composite tertiary amine, which can strongly catalyze the urea (water-isocyanate) reaction of rigid spray polyurethane foam, thereby greatly increasing the foaming reaction time. The PT303 catalyst contains groups that can react with isocyanate, which can form a chemical bond with the polyurethane foam matrix, thereby reducing the smell of spray foam.

Typical physical properties:

Appearance Light yellow transparent liquid
Proportion 0.84
Viscosity@25℃ mPa.s 5
Water-soluble 25℃ completely dissolved
Flash point, ℃ 72

Features:

Strong blowing catalyst with similar activity to 5 catalyst

lower odor than traditional 5 catalyst

Recommendations:

PT303 catalyst can be used for rigid foam applications, especially rigid spray foam.

The usage amount of PT303 catalyst can be adjusted according to the formula, use and requirements. It can be used together with PT302 and PT304 catalysts in spray hard foam formulations.

Shelf Life:

Keep it unopened for two years

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse

Packaging:

200KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Store in a cool, dry place, keep the container tightly closed, and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry and cool place with proper ventilation. All storage containers must be well sealed to avoid contact with water or other influential substances, as this may change the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are inappropriate and should be avoided as much as possible.
