单组份（聚氨酯）密封胶用途

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。
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.

This sealant is a solvent-free, one component curable sealant at room temperature. 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. The market in the southwest of Chongqing Xinhe plastic in the production of such products.
聚氨酯密封胶广泛用于土木建筑、交通运输等行业：
Polyurethane sealant is widely used in civil engineering, 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 seals for 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.
“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。
"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; while the single components used directly, convenient and 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.
与传统的硅酮胶相比，聚氨酯胶具有3倍以上的高伸长率和2倍以上的粘接强度。
Compared with the traditional silicone adhesive, polyurethane adhesive has more than 3 times higher elongation and more than 2 times of bonding strength.
单组分聚氨酯胶完全固化后无毒，可以用于饮水工程，已经经过权威测试的。
One component polyurethane glue is nontoxic after being completely solidified. It can be used in drinking water engineering and has been tested by authority.
