單組份聚氨酯密封膠規格@錦州
單組份聚氨酯密密封膠是一種無溶劑單組分室溫固化密封膠。該密封膠呈膏狀，可擠出或涂抹施工。有抗下垂性，嵌填垂直接縫和頂縫不流淌。固化后的膠層為橡膠狀，有彈性。對金屬、橡膠、木材、水泥構件、陶瓷、玻璃等有粘附性。密封膠是用來填充空隙(孔洞、接頭、接縫等)的材料，兼備粘接和密封兩大功能。
One component polyurethane sealant thick is a solvent free single component room temperature curing sealant. The sealant is paste and can be extruded or painted. There is resistance to sag, filling the vertical joints and the top seam does not flow. The cured rubber layer is rubbery and elastic. Adhesion to metals, rubber, wood, cement, ceramics, glass, etc.. Sealant is used to fill voids (holes, joints, joints, etc.) of materials, both adhesive and sealing two major functions.
聚氨酯密封膠廣泛用于土木建筑、交通運輸等行業：
Polyurethane sealant is widely used in civil, construction, transportation and other industries:
1.在建筑方面的應用——門窗、玻璃等的填充密封；
1. architectural applications - doors and windows, glass and other filling seal;
2.在土木方面的應用——高速公路、橋梁、飛機跑道等的嵌縫密封；
2. in civil applications, highways, bridges, runway caulking sealing;
3.在汽車方面的應用——車窗（主要是風擋玻璃）的裝配密封。
3. automotive applications - assembly seal for windows (mainly windshield).
密封膠是用來填充空隙（孔洞、接頭、接縫等）的材料，兼備粘接和密封兩大功能。聚氨酯密封膠與硅酮密封膠、聚硫密封膠構成了目前高檔密封膠的三大品種。
Sealant is used to fill voids (holes, joints, joints, etc.) of materials, both adhesive and sealing two major functions. Polyurethane sealant and silicone sealant, polysulfide sealant constitute the current high-grade sealant three varieties.
“單組分”主要是相對“雙組分”而言的，有一種雙組分聚氨酯膠，在使用的時候需要將A、B組分，按比例均勻地混合才能起到粘接密封的效果；而單組分則直接使用，方便、簡潔，施工簡便。“濕固化”是指，單組分聚氨酯膠是利用于空氣中的微量的水蒸氣反應而固化，與基材表面的活性基團反應起到粘接作用。
"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 the micro reaction of water vapor in the air and reacts with the active group on the substrate surface to act as bonding.
與傳統的硅酮膠相比，聚氨酯膠具有3倍以上的高伸長率和2倍以上的粘接強度。
Compared with traditional silicone adhesive, polyurethane adhesive has more than 3 times higher elongation and more than 2 times adhesive strength.
單組分聚氨酯膠*固化后無毒，可以用于飲水工程，已經經過測試的。
One component polyurethane glue is non-toxic after being compley solidified. It can be used in drinking water engineering and has been tested by authority.
