Dissolving the resin:-

  1. Take all water** in the mixer***.
  2. Add required amount of spreacol 500 MIX and mix until a homogenous solution is obtained.
  3. Other additives are added.

*Flour is added in case of gluing veneer to plywood.

**Water temperature should be 20 – 30 0C because with lower temperature mixing is more time

consuming.

***A mechanical stirrer may be used for this purpose,With high speed mixer all the water may be

placed first and then resin may be added, while mixer is running.With low speed mixer, it is better

to make a homogenous mix of the resin with about 2/ 3 of water, and rest of the water may be

added later
