Urea formaldehyde (UF) is a value-powerful thermosetting resin that is widely used in the wood merchandise business. In the laboratory, urea formaldehyde resins are prepared by dealing with urea with formaldehyde in an alkaline or neutral medium to create dimethylol urea, which then undergoes polycondensation, a chemical method that benefits in a polymer, when heated in an acidic medium.
These resins remedy easily and are scratch resistant. They are mostly utilized in adhesives, finishes, particle board, MDF, and molded objects. UF and connected amino resins are regarded a course of thermosetting resins of which urea-formaldehyde resins make up 80% made EPTly.
Urea formaldehyde resin powEPTusing and sage Approach:
one.Pretreatment for gluing wooden material:
A) Dampness articles achieve to 10 two%
B)Eliminate Knots Cracks, oil stain and resin etc.
C) Wood surface should be flat and sleek. (Thickness Tolerance lt0.1mm)
A) Mixture Ratio (excess weight): UF Powder: H2o=one: 1(Kg)
B) Dissolution Approach:
Put two/3 of the total needed drinking water into mixer, and then incorporate UF powEPTin. Switch on the mixer with velocity of 50~a hundred and fifty rotations / minute, right after glue powEPTbeing completely dissolved in water, set the remained 1/3 drinking water in mixer and stir for 3~5minutes until glue to being entirely dissolved.
C) Workable period of time of dissolved liquid glue is 4~eight hrs unEPTroom temperature.
D) The consumer could incorporate hardener into the combined liquid glue according to real requirement and management the lively period of dissolved (if incorporate hardener, the period of time of validity will be limited, and if use unEPTa heat temperature, no need to have to include hardener)
1.1. PowEPTurea formaldehyde resin ought to be held unEPTseal to steer clear of direct sunligEPT and to avoid contact with dampness
2.two. PowEPTurea formaldehyde resin unintentionally splashed into the eyes, use plenty of h2o washing, if essential, seek healthcare suggestions
