導(dǎo)讀:目前,很多行業(yè)的材料都向輕量化發(fā)展。結(jié)構(gòu)膠粘劑同樣如此。為適應(yīng)結(jié)構(gòu)膠粘劑這一發(fā)展新趨勢(shì),美國(guó)卡德萊公司推出了高性能環(huán)氧樹脂固化劑NX-5607和NX-5608,NX-5607和NX-5608已經(jīng)成功應(yīng)用于汽車用膠粘劑,工業(yè)用膠粘劑,維修等領(lǐng)域。
這些固化劑主要是是使用腰果殼油等原料,目的是針對(duì)極具挑戰(zhàn)性的性能,以及滿足膠粘劑行業(yè)相關(guān)的監(jiān)管要求,產(chǎn)品特點(diǎn)包括:不含任何溶劑,也無(wú)需在配方中通過(guò)添加任何溶劑來(lái)獲得優(yōu)異性能,施工期短、與新型建筑材料之間具有優(yōu)異的附著力,耐久性能優(yōu)異。
關(guān)于卡德萊:卡德萊是運(yùn)輸和剎車工業(yè)中使用的高性能腰果殼油粘合樹脂的龍頭生產(chǎn)商。這些熱固化樹脂是與四氮六甲圜進(jìn)行化學(xué)交聯(lián),將剎車帶,剎車片,剎車片和皮帶結(jié)合一起。腰果殼油樹脂也許是最好的改性酚醛樹脂,具有直酚醛的各種優(yōu)質(zhì)特征(抗沖擊性,韌性,熱穩(wěn)定性),而且不會(huì)產(chǎn)生油面現(xiàn)象。油面現(xiàn)象會(huì)導(dǎo)致摩擦系數(shù)的減少。
卡德萊粘合樹脂有各種不同的粘度,固體份(特殊溶劑或者無(wú)溶劑),以及改性特點(diǎn),滿足不同的使用要求。這些樹脂作為摩擦材料粘合劑用于石棉和非石棉滾壓剎車帶和亞光段,以及重型機(jī)車和火車閘瓦領(lǐng)域。在其他應(yīng)用領(lǐng)域,例如替代剎車帶和輪胎邊芯的桐油領(lǐng)域,粘合樹脂也能派上用場(chǎng)。

Cardolite Presents Recently Developed Phenalkamines for Structural Adhesives
Cardolite Corporation presents NX-5607 and NX-5608 high performance phenalkamine epoxy curing agents to address new trends in the development of structural adhesives. Leveraging the inherent benefits of cashew nutshell liquid (CNSL) derived materials, these curing agents were designed to satisfy the challenging performance and regulatory requirements of the adhesive industry including: solvent-free and label-friendly formulations, fast processing, excellent adhesion between new construction materials, and increased durability.
As many industries move to lighter weight materials, the next generation of structural adhesives is expected to be versatile and deliver the same level of adhesion for lighter materials as they do for steel. By providing high adhesion and mechanical strength to bonds between various composite, aluminum and plastic substrates, NX-5607 and NX-5608 allow the same adhesive to be used in multiple parts of a job. These products also have high glass transition temperatures to help withstand external stress and excellent hydrophobicity to minimize moisture absorption. These two features allow for more durable bonds which in turn lead to more sustainable products.
Although new levels of performance are demanded from structural adhesives, the adhesive industry continues to face pressure to reduce costs and use non-toxic, consumer-friendly chemicals. NX-5607 and NX-5608’s fast bond strength development, even at low temperatures and high humidity, offers both time and cost savings by increasing productivity, widening the application window, and lowering the risk of adhesion failure due to uncontrollable environment conditions. To meet rising toxicity concerns and lower volatile organic compound (VOC) emission targets, these products contain no solvents, phenols, or benzyl alcohol.
Marketed and volume produced by Cardolite for over a year, NX-5607 and NX-5608 have been successfully formulated in adhesives for automotive, industrial, field-applied construction, rapid-set repair, and maintenance applications.
