Product description
1.General Introduction
Urea formaldehyde (UF) is a cost-effective thermosetting resin that is widely used in the wood product industry. In the laboratory,urea formaldehyde resins are prepared by using urea with formaldehyde in an alkaline or neutral medium to produce dimethylol urea,which then undergoes polycondensation, a chemical process that produce a polymer,when heated in an acidic medium.
2.Application
Urea formaldehyde resin cure easily and are scratch resistant.They are mainly used in adhesives,finishes,particle board,MDF and molded objects.UF and related amino resins are considered a class of thermosetting resins of which urea-formaldehyde resins make up 80% globally.

1.Urea Formaldehyde Resin Powder Using and Sage Method
1. Pretreatment for gluing wood material:
A) Moisture content reach to 10 + 2%
B) Remove Knots, Cracks, oil stain and resin etc.
C) Wood surface must be flat and smooth. (Thickness Tolerance<0.1mm)
2. Mixture:
A) Mixture Ratio (weight): UF Powder: Water=1: 1(Kg)
B) Dissolution Method:
Put 2/3 of the total needed water into mixer, and then add UF powder in. Switch on the mixer with speed of 50~150 rotations / minute, after glue powder being completely dissolved in water, put the remained 1/3 water in mixer and stir for 3~5minutes till glue to being completely dissolved
C) Workable period of dissolved liquid glue is 4~8 hours under room temperature.
D) The user could add hardener into the mixed liquid glue according to actual requirement and control the active period of dissolved (if add hardener, the period of validity will be short, and if use under a heat temperature, no need to add hardener)
