聚氨酯发泡剂 

　　格宁科温聚氨酯泡沫填缝剂是一种单组分、湿气固化、多用途的聚氨酯发泡填充弹性密封材料。
　　聚氨酯泡沫填缝剂是将聚氨酯预聚体﹑发泡剂﹑催化剂等组分装填于耐压气雾罐中的特殊聚氨酯产品。
　　施工时通过配套施胶枪或手动喷管将气雾状胶体喷射至待施工部位，短期完成成型、发泡、粘结和密封过程。
　　其固化泡沫弹性体具有粘结、防水、耐热胀冷缩、隔热、隔音甚至阻燃(限阻燃型)等优良性能，广泛用于建筑门窗边缝、构件伸缩缝及孔洞处的填充密封。

　　The Geningcoven polyurethane foam sealant is a one-component, moisture-cured, multi-purpose polyurethane foam filling elastic sealing material. Polyurethane foam sealant is a kind of special polyurethane product, which is composed of polyurethane prepolymer, foaming agent, Catalyst, etc. . During construction, the aerosol colloid is sprayed to the site to be constructed by matching glue gun or manual nozzle, and the process of molding, foaming, bonding and sealing is completed in a short time. The cured foam elastomer has excellent properties such as bonding, waterproof, heat-resistant expansion and contraction, heat insulation, sound insulation and even flame retardant (limited flame retardant type) , it is widely used to fill and seal the side seam of doors and windows, expansion joint of components and holes
