(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

由表5可知，隨著固化溫度(105℃,115℃,125℃,135℃ ,145℃)逐漸升高，表面電阻值均穩(wěn)定在1.8x10'0 f2左右。因此，在選擇固化溫度時，表面電阻值不是主要的考慮因素。因此，本研究選擇125℃作為固化溫度。催化劑T-12用量對硅烷改性聚氨酯密封膠性能影響。
由表6可知，在選擇催化劑T-12用量時，表面電阻值不是主要的考慮因素，最佳催化劑用量為0. 09 %�？轨o電劑用量對硅烷改性聚氨酯密封膠性能影響由表7可知，隨著抗靜電劑JL-WT1用量(0.2%,0.5%,0.8%,1.1%,1.4%)逐漸加大，剝離力均穩(wěn)定在6. 1-25 mm左右，基本保持穩(wěn)定，由此可見，抗靜電劑用量對剝離力的影響較小，在選擇抗靜電劑用量時，剝離力不是主要的考慮因素。經(jīng)過200℃烘烤后，剝離力有所增加。當抗靜電劑JL-WT1用量為1. 1%時，剝離力200℃烘烤后的值最低。選擇抗靜電劑用量為1. 1%獲得較低的剝離力，從而提高硅烷改性聚氨酯密封膠的熱穩(wěn)定性。經(jīng)過200℃烘烤后，抗靜電劑JL-WT1用量為1. 1%時，膠膜的性質(zhì)最好，沒有殘膠和轉(zhuǎn)移現(xiàn)象。隨著抗靜電劑JL-WT1用量的增加，表面電阻值逐漸減小。當抗靜電劑JL-WT1用量為1. 1%時，表面電阻值最低，為1. 8x 10$ f2。綜上，在選擇抗靜劑用量時，表面電阻值是一個重要的考慮因素，本研究選擇1. 1%的抗靜電劑JL-WT1用量為最佳。http://ago-games.com/
