Product Description

1. What is Urea Formaldehyde resin

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 treating urea with formaldehyde in an alkaline or neutral medium to produce dimethylol urea, which then undergoes polycondensation, a chemical process that results in a polymer, when heated in an acidic medium.

2. Application
It can be used for products with low requirements for water resistance and dielectric performance, such as patch panels, switches, machine handles, instrument casings, knobs, daily necessities, decorations, mahjong tiles, toilet covers, and can also be used for the manufacturing of some tableware.
Urea formaldehyde resin is the most commonly used type of adhesive, especially in the manufacturing of various artificial boards in the wood processing industry. Urea formaldehyde resin and its modified products account for about 90% of the total amount of adhesive used.

UF has many kinds of content based on the different usage.
4.Usage and Dosage 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).
