AUCAT series catalysts are developed for the disadvantage that ordinary organometallic catalysts gradually fail in systems containing trace water, acid and alkali and can not be stored stably for a long time.
Product Brief：
AUCAT series catalysts are developed for the disadvantage that ordinary organometallic catalysts gradually fail in systems containing trace water, acid and alkali and can not be stored stably for a long time.
Typical Properties：
Model | Appearance | Colour （Fe-Co） | Density g/cm3 (25℃) | Viscosity mPa.s (25℃) | Smell |
AUCAT-101 | Yellowish transparent liquid | ≤3 | 1.090 | 14000±3000 | With special compound smell |
AUCAT-201 | 1.059 | 6200±1000 |
Environmental protection:
It does not contain heavy metals strictly controlled by environmental protection regulations.
Solubility：Easily soluble in various polyesters, polyether polyols, hydroxypropyl resin, etc
Applications：
It is widely used in 2K oily polyurethane coatings and hydroxy acrylic coatings. It can be pre added to the coatings for stable storage without failure, so as to solve the problem of activity attenuation and failure of bismuth and tin catalysts in use. AUCAT-101 can also be used for coating resin synthesis.
Features & Advantage:
AUCAT series catalysts are developed for the disadvantage that ordinary organometallic catalysts gradually fail in systems containing trace water, acid and alkali and can not be stored stably for a long time. They have the features and advantages as follows:
Environmental protection. It does not contain harmful heavy metal elements such as mercury / tin / lead, so as to ensure that it meets the stringent requirements of environmental protection regulations at home and abroad. Organotin, as a catalyst, has always occupied a leading position in the polyurethane industry, but its toxicity and harm to the environment have attracted extensive attention. In recent years, many environmental protection regulations at home and abroad have strictly restricted organotin, which is tantamount to being banned. It is no longer suitable for market development and demand, and most enterprises have already started its elimination and substitution.
Hydrolysis resistance and no failure of catalyst. Solve the technical problem of gradual hydrolysis failure of metal catalysts such as ordinary organic bismuth / tin in 2K oily polyurethane coating due to a large number of polar solvents and high moisture content. It can be stored in the coating for a long time, the catalytic activity is stable and does not decay, and the formula and process are simpler, stabler and more flexible.
Highly compatible with resin without losing gloss. It has good compatibility with 2K Polyurethane Coatings such as hydroxypropyl resin and polyester resin, good film transparency and high gloss.
Eliminate or reduce bubbles, bulges, pitting and other adverse phenomena. AUCAT-101/201 selectively catalyzes the reaction between isocyanate and -OH, and the reaction between trace water and isocyanate in the environment is very weak or even not catalyzed, which avoids CO2 produced by chemical reaction, which can effectively reduce pitting in the paint film.
Long pot life and fast curing. AUCAT-101 has high catalytic activity. When used in 2K oily polyurethane coatings, it can significantly accelerate the drying of paint film and improve the wear and scratch resistance of paint film; AUCAT-201 has mild catalytic activity and long pot life. It can promote the crosslinking and drying of paint film. It can be used in combination with AUCAT-101 to adjust the curing speed.

User's Guide:
If it is used for two-component polyurethane acrylic coating, the general addition amount is 0.05-0.2% of the weight of coating components.
The addition time is usually in the paint mixing stage, and it is not recommended to add in the grinding stage to prevent the catalyst from being adsorbed by the powder and affecting the catalytic effect;
The method of adding while dispersing can be adopted. Due to the small amount of addition, it is recommended to add after diluting with an appropriate amount of solvent in advance.
The packaging container must be kept closed normally. After use, the opening of the container should be sealed.
Handling & Storage:
Product should be stored in a cool, dry environment away from sunlight, excessive heat and rain.
Package: 25kg/200kg in HDPE drum
Shelf Life: The unopened shelf life is 18 months from the date of manufacture. After shelf life, please do test to make sure the catalytic properties before use.
