Hardener for Urea-Formaldehyde Resin Curing Agent¹

Product Description Product IntroductionHardener for UF resinApplication:UF-A0012 is an aqueous hardener especially designed to be used with UF resins in the impregnation of all type of papers. It efficiently cures urea-formaldehyde resin which helps to reduce the possibilty of quality problem and paper adhesive problem. Through the use of UF-A0012, it can improve melamine paper pressing curing temperature and prolong resin flowing time, reduce the possibility of dried/wet flower problem, also it improves the heat-resisitent temperature of melamine paper storing which lenghthen the storing time.Specifiction: AppearanceLiquidColorColorless or yellowRelative density 1.2-1.27 g/cm3PH range6.5-7.5Use quantity0.2-0.3%Storage conditionsUnder 25oC, stored in a sealed container, the shelf life is one yearIf the temperature is too high, the shelf life will be shortenIf the temperature is too low, it will not affect the performance of product.Packing specification200KG/drum or 1000KG/barrel Low mole ratio F/U(1.1:1) urea-formaldehyde(UF) resin was prepared with high concentration formaldehyde.Evaluation and analysis of bonding performance and heat resistance of this resin was studied based on three different curing agent(NH_4Cl, HCOOH, NH_4Cl + urea) by 13C-NMR and DMA.The results show tha t this resin had significantly high v iscosity and solid content, and free formaldehyde content was low to 0.075%.Hydroxymethyl content, degree of polycondensation and crosslinking of this resin increased by 6.33%, 5.87% and 6.33% respectively.Compared with common UF resin, bonding strength of this UF resin was higher by 74% and 78% when NH_4 Cl and HCOOH were as the curing agent.Only with HCOOH as curing agent, this resin had excellent heat resistance. Lead timeQuantity (tons)1 - 10> 10Lead time (days)30To be negotiatedOur Customer Q1.Do you have MOQ?
