聚硫建筑密封膏系列使用时候的注意事项：

1、适用期：聚硫建筑密封膏甲、乙组分混合后，混合料逐渐变稠，超过适用期就不能使用。使用时的环境温度对聚硫建筑密封膏的固化起相当大的作用，气温越高适用期越短，气温过低时固化速度变慢，施工温度以5℃～35℃为宜。

2、使用时，聚硫建筑密封膏的宽深比例要适当。

3、聚硫建筑密封膏贮存时要避免太阳直晒，宜放在阴凉干燥处。在5～26℃环境温度下可贮存半年，时间过久会影响其物理及使用性能。比如SS521是单组分、中性固化，专为玻璃、铝板幕墙和玻璃采光顶及金属结构工程的结构粘结密封而设计的硅酮结构密封胶，聚硫建筑密封膏具有优异的结构粘结性能和耐气候老化性能，经过人工加速气候老化测试，聚硫建筑密封膏的各项理化性能无明显变化。

Generic names: polysulfide sealant building (glue), waterproof two-component polysulfide sealant (cream), PS852 of two-component polysulfide sealant (cream), PG321 a two-component polysulfide sealant (cream), SGJL - 851 two-component polysulfide sealant (glue)

【 product technical performance 】

The performance of the complexes:

Not droop type, high elongation, low modulus of polysulfide sealant building completely cured for rubber high elastomer. Mix: master agent (A) : curing agent = 100 (B) : 10 (quality, standard conditions), the seasons, regional temperature changes. Available curing agent usage, how to adjust the length of the applicable period, changes in the B component range between 8 and 12.

【 features 】

L, caking: polysulfide sealant of cement, steel, glass, wood, natural stone material and so on all have good cohesiveness. The appropriate on general construction and water conservancy project using low modulus, high elongation of polysulfide sealant, its bond strength 0 or higher. 2 mpa, the elongation is 300% or higher.

2, water resistance, polysulfide sealant in sea water, tap water and distilled water is stable, compared with minimal weight change of the sea (salt).

3, acid, alkaline, polysulfide sealant is not resistant to strong acid, alkali. But for dilute mineral acid, alkali and salt is stable.

4, heat aging resistance, thermal aging polysulfide sealant performance is very good, can long-term in a 40 ℃ ~ 120 ℃ under the condition of work.

5, good radiation resistance: polysulfide sealant r_ radiation resistant performance is very good.
