    Description

    CPU-76-113G is an excellent two-component polyurethane resin. It has high transparency and great adhesion to various substrates. It’s reinforced to possess better weathering-resistance. It can withstand vicious surroundings, including cold, hot, dry or wet environments.

     

     

    Guidelines for Manual Processing

    1. Keep the operation place as dustless as possible to gain products with better appearance. The ambient temperature is recommended at between 15°C and 25°C.

     

    1. Calculate the needed amount in weight. Pour Part A in half of the total amount into a clean and dry container, and then pour the same quantity of Part B into the container. The weight ratio of Part A to Part B is 1:1. Unused components must be tightly closed to prevent contamination of dust and moisture from the air.

     

    1. Agitate the mixture with an electric stirrer or manually with a stirring blade. Agitate it for 30 seconds to 1 minute till it is mixed completely.

     

    1. Place the well blended mixture in a degassing system for 1 to 4 minutes.

     

    1. Immediately start dispensing the mixture onto substrates. The operating time is about 10 to 20 minutes. Higher the ambient or resin temperature and more the blended amount, the operating time would be shorter.

     

    1. Put the coated substrates in an oven. Higher the oven temperature, they can be cured faster. Normally they can be cured in one and half an hour at 80°C. For other curing temperatures and periods, please refer to the following table. As there’re always some tiny bubbles remaining in the mixture, a blast of hot air by a flame gun is helpful to eliminate residual bubbles near the surface.

    Handling & Safety

    1. Please wear a mask of charcoal filter, gloves and goggles while operating. And keep good ventilation.
    2. In case contacting the resin, no matter which part of the body, please wash it with plenty of soap and water at once. See medical attention, if you feel unwell.
