       This product is used as a two-component non-yellowing polyurethane coating curing agent, with good weather resistance.

 general shape

 Features 
 CORONATE HXR as a non-yellowing polyurethane coating curing agent, trimer has better properties than other biuret type and amino adduct type curing agents. CORONATE HXR has good heat resistance and good compatibility when mixed with polyols or solvents, and can be widely used in motorcycle parts, auto repair, wood furniture and so on.

application
The non-yellowing paint produced by CORONATE HXR mixed with acrylic polyol has good weather resistance and UV resistance, so it can maintain the original color of the paint for a long time. This two-pack paint is ideal for automotive surface coatings and other industrial applications. It forms a two-component coating with alkyd resin and can be used in woodworking applications.

Solubility
CORONATE HXR is soluble in most ester and aromatic hydroxy solvents. For example: butyl acetate, butyl ester, toluene, xylene, etc. But aliphatic solvents are not suitable for isocyanates.

Operating Rules

Storage Conditions
CORONATE HXR should always be stored in an airtight container at room temperature. Since it is extremely reactive with active hydrogen groups, it should avoid contact with moisture in the air. For long-term storage, it should be stored indoors at room temperature (15 – 25C).
when using it
If the NCO group in this product reacts with water, some insoluble substances such as urea group and CO2 gas will be generated, which will increase the pressure in the closed container and cause the container to expand. When accessing this product or emptying the raw material barrel, care should be taken to avoid moisture contamination. The operation of transferring the raw material to the container must also be carried out in a dry environment, and the container must be nitrogen filled before sealing.
when diluted
When diluting this product, a solvent with low water content should be used as much as possible, and attention should be paid to avoid contact with water during the dilution operation. The dilution operation must be carried out in a dry environment.

safety measures
Because CORONATE HXR contains reactive isocyanates and solvents, please pay attention to safety when using it. Please refer to the MSDS safety instructions for proper use and operation before using this product. This product is flammable and should be constructed in a non-smoking area. In order to prevent this product from coming into contact with the skin, please follow the safety operation rules and wear protective equipment such as safety glasses and safety gloves when using it. CORONATE HXR is mainly used for spraying paint. To prevent the dust from being inhaled into the human body, please wear a gas mask or protective mask. The free isocyanate content of CORONATE HXR is less than 0.2%, and it will not increase in long-term storage.
