Chinese Name: 脲醛胶Hh高分子防老剂

外文名Foreign Name: Urea-Formaldehyde Glue Hh Polymeric Anti-aging Agent

一、I.Functions and Features of the Products:

It has the excellent properties such as inhibition of urea-formaldehyde glue reaction until end point, amplification of molecular weight, hot measurement glue without adhesion for 30s, reduction of free formaldehyde smell, shortening of curing time, increase of hot-pressing forming speed, improvement of fiber moisture without separation, and enhancement of internal bond strength, surface bond strength and thickness absorption, without changing the mole ration formula of various glues.

This product is the world’s unique new material that can inhibit and prevent the aging effect of urea-formaldehyde glues. It can effectively inhibit and prevent resin aging in the polycondensation reaction or storage process of urea-formaldehyde glue( to extend the storage life of the glue so that it will not loss its use performance within 3-5 months). Its primary functions are anti-heat and oxygen aging and antiozone aging. Moreover, it has very obvious anti-aging protective effects of metal ion, light and heat.

二、II. The product is light yellow resin power in appearance, with a boiling point of 88—95°。

三、III. Range of Application

广泛适用于E1级、E0级、P2级中（高）密度板、刨花板、胶合板、细木工板环保胶的生产。

It is widely used in production of Level E1, E0 and P2 high (medium) density board, chipboard, plywood, core-board environmental glues.

四、IV. Additive Amount

按防老剂含量每吨甲醛计算添加： AAAA型{bfb}含量添加6.25kg。

Without changing the manufacturer’s technical formula, it shall be calculated according to original mole ratio of ordinary glue, level E2, level E1 and level E0; the additive amount of the anti-aging agent per ton of formaldehyde: Add 6.25kg AAAA type {bfb} content anti-aging agent.

五、Addition Method:胶使用时,请厂人员在我方技术人员的指导下添加。

When the product is used for production of urea-formaldehyde glue, the technician of glue factory shall add the product under the guidance of our technician.18982082185 3981864222
