UREA FORMALDEHYDE POWDER RESIN
Use
Paper pencils, Wooden pencils
Characteristic
UF-2301 is the thermosetting polymer. It is two components. According to the users needs, appropriate to different curing agent to adjust the use and hardening of time. UF-2301 can be dissolved with water in advance to save time before sizing. This product has good adhesion, high water resistance, fast curing time, low thermal curing, mould proof, transportation and convenient storage of superior performance.

Use methods
The powder ratio of powder: water is 2:1 by weight to fully dissolve in water, until no solid matter in the presence of liquid. Then add the hardeners (1% to 3% of the powder). The use of curing agent decides by the ambient temperature and the pot life. The modulation of the glue can immediately gelatinize.

Note
UF-2301 is moisture absorbent and quickly becomes knotted losing effect and fluidity. It is usually packed in moisture-proof bags. Bags with remaining powders should be resealed after use.
