1、单组份聚氨酯密密封胶是一种无溶剂单组分室温固化密封胶。该密封胶呈膏状，可挤出或涂抹施工。有抗下垂性，嵌填垂直接缝和顶缝不流淌。固化后的胶层为橡胶状，有弹性。对金属、橡胶、木材、水泥构件、陶瓷、玻璃等有粘附性。密封胶是用来填充空隙（孔洞、接头、接缝等）的材料，兼备粘接和密封两大功能。

1, one component polyurethane sealant thick is a solvent free single component room temperature curing sealant. The sealant is paste and can be extruded or smeared. It has sagging resistance, and the vertical joint and the top seam are not flowing. The cured adhesive layer is rubbery and elastic. Adhesion to metals, rubber, wood, cement components, ceramics, glass, etc.. Sealant is used to fill voids (holes, joints, joints, etc.) of materials, both adhesive and sealing two functions.
2、单组份聚氨酯密封胶广泛用于土木建筑、交通运输等行业：
2, one component polyurethane sealant is widely used in civil construction, transportation and other industries:
(1)在建筑方面的应用——门窗、玻璃等的填充密封；
(1) application in Architecture -- filling seal of doors and windows and glass;
(2)在土木方面的应用——高速公路、桥梁、飞机跑道等的嵌缝密封；
(2) in civil applications, highways, bridges, runway caulking sealing;
(3)在汽车方面的应用——车窗（主要是风挡玻璃）的装配密封。
(3) automotive applications - assembly seal of windows (mainly windshield).
密封胶是用来填充空隙（孔洞、接头、接缝等）的材料，兼备粘接和密封两大功能。聚氨酯密封胶与硅酮密封胶、聚硫密封胶构成了目前高档密封胶的三大品种。
Sealant is used to fill voids (holes, joints, joints, etc.) of materials, both adhesive and sealing two functions. Polyurethane sealant and silicone sealant, polysulfide sealant constitute the current top grade sealant three varieties.
3、单组份聚氨酯密封胶特性：性能可调范围宽、适应性强；耐磨性能好；机械强度大；粘接性能好；弹性好，具有优良的复原性，可用于动态接缝；低温柔性好；耐候性好，使用寿命长达15~20年；耐油性好；耐生物老化；价格适中。
3, one component polyurethane sealant performance characteristics: wide adjustable range and strong adaptability; good wear resistance; high mechanical strength; good adhesion; good elasticity, has excellent resilience, can be used for dynamic joint; low temperature flexibility; good weather resistance, long service life for 15~20 years; good oil resistance; resistance to biological aging; moderate price.
4、单组份聚氨酯密封胶优势：“单组分”主要是相对“双组分”而言的，有一种双组分聚氨酯胶，在使用的时候需要将A、B组分，按比例均匀地混合才能起到粘接密封的效果；而单组分则直接使用，方便、简洁，施工简便。“湿固化”是指，单组分聚氨酯胶是利用于空气中的微量的水蒸气反应而固化，与基材表面的活性基团反应起到粘接作用。
4, one component polyurethane sealant: "single component" is relative to "double component", there is a two-component polyurethane adhesive, when in use will need A, B component, according to the proportion of mixed evenly to adhesive sealing effect; and the single components to be used convenient, simple, convenient construction. "Wet curing" means that a single component polyurethane adhesive is cured by a small amount of steam reaction in the air and acts as a bonding agent to the active group on the substrate surface.
