STRANGE-468PU胶粘剂
 
 
                               STRANGE-468PU胶粘剂
 
 STRANGE-468PU胶粘剂 是一种改性聚氨酯胶粘剂。用于三明治结构粘接.可用做木材、玻璃钢板、铝板、钢板等材料与各类蜂窝结构、聚氨酯夹芯板、聚苯乙烯泡沫板等的结构粘接。
产品特性
 对各种基材表面粘接力优异;
 固化速度快,缩短冷压或热压的时间;
 优良的耐湿热性能,耐候性良好;
使用方法
a、基材的表面处理
  基材表面应该干燥,无油脂,无灰尘或其它污物(可用乙醇、丙酮等清洗)。若金属表面涂有底漆或被粘表面经过打磨处理,粘接力会明显增加;
b、配比
  AB  2:1主剂在使用前请先搅拌均匀。严格按要求比例进行机械(手工)混合,快速搅拌至颜色均一以后,再搅拌1~2分钟即可;
c、涂胶
  根据基材表面情况,平面涂胶量于 300g左右;实际施工时,会随基材表面平整度的不同,施胶量略有变化;涂胶可采用合适的带齿刮板、平刮板刮胶或滚涂上胶,也可采用涂胶机机器上胶;
  胶黏剂按比例配完后请于适用期以内,涂于基材表面。已经施胶的基材需要在开放时间以内进行压合,否则影响粘接强度。在不影响材料成型的情况下,应尽可能提高复合压力;
d、施压时间
  根据温度不同,固化速度不同,形成粘接力的时间也不同。温度降低,固化速度变慢,需要延长施压时间。温度升高,固化速度变快,需要的施压时间短。23℃情况下,卸压时间需要5-8小时,7天完全固化;
e、工作环境
 在-5~40℃,相对湿度80%以下进行操作;
包装规格:55加仑
 
 
STRANGE-468PU adhesive is a kind of modified polyurethane adhesive. Adhesive used for sandwich structure. Can be used as wood, glass steel, aluminum, steel and other materials and all kinds of honeycomb structure, polyurethane sandwich panel, polystyrene foam board, etc. The structure of the adhesive.
Product features:
For a variety of substrate surface sticky relay is excellent;
Fast curing speed, shorten the time of cold or hot pressing;
Excellent wet and heat resistance, good weatherability;
Method of use:
A, base material surface treatment
Base material surface should be dry, no grease, no dust or other contaminants (or ethanol, acetone and other cleaning). If the metal surface coated with primer or glued surface after polishing treatment, stick relay can obviously increase;
B, the ratio of
AB 2:1 main agent please stir well before use. In strict accordance with the requirements for mechanical proportion (manual), quick stir until after color uniform, 1 ~ 2 minutes; stir again
C, glue
According to the base material surface, surface coating amount to about 300 g; Actual construction, with different substrate surface roughness, sizing quantity changes slightly; Glue can adopt appropriate toothed scraper, scraper scraping gum or roller coating glue, also can use glue machine machine glue;
After the adhesive in proportion with period of less than, please apply on substrate surface. Have glue base material need to be done within the open time of pressing, otherwise affect the bonding strength. In does not affect the material forming the situation, should increase composite pressure as far as possible;
D, pressing time
According to the different temperature, curing speed, forming sticky relay time is different also. Temperature is reduced, curing speed slow, need to extend the time pressure. Temperature, curing speed faster, need the pressure of time is short. 23 ℃, unloading time need 5-8 hours, 7 days completely curing;
E, the working environment
In 5 ~ 40 ℃, relative humidity below 80% for operation;
Packing specification: 55 gallon
