Dissolving the resin:-

  1. Take all water** in the mixer***.
  2. Add required amount of MUF and mix until a homogenous solution is obtained.
  3. Hardener is added.


  • The hardener quantity depends on pressing conditions like temperature, timing, pressure, and thickness.
  • Water temperature should be 20 – 30 0C because with lower temperatures mixing is more time-consuming.
  • A mechanical stirrer may be used for this purpose. With a high-speed mixer, all the water may be placed first and then resin may be added, while the mixer is running. With a low-speed mixer, it is better to make a homogenous mix of the resin with about 2/ 3 of water, and the rest of the water may be added later.

  • Very good adhesives for wooden materials.
  • Wide variety of end uses such as wood-based panels, furniture, load – bearing constructions, and wooden building products.

Packing:  • 25 Kg net laminated polyethylene bags.


Handling: Like any formaldehyde product, MUF contains free formaldehyde. This may cause dermatitis when it comes into contact with the skin of sensitive persons. Skin contact with powder should be avoided. Hands should be thoroughly washed with soap and hot water at the end of the working day and before meals. A dust mask should be worn while emptying the bags.          


Storage: The powder should be stored in the original bags in a cool place protected from heat. Care should be taken that powder doesn't absorb moisture and water. The bags which have been opened should be carefully closed before storage. When stored in original bags at 200C, the shelf life would not be less than one year.
