Structure & Industrial
The structural adhesive is needed to bond multiple identical or different substrates together. Compared to adhesives used for other purposes, structural adhesives are required to withstand the forces involved during the product's service life. These forces can be either constant loads or intermittent. They are also susceptible to various external factors that can weaken or damage them, such as impact, vibration, chemical exposure, temperature fluctuations, and more.
Common structural adhesives include anaerobic adhesives, cyanoacrylate adhesives, epoxies, methacrylates, polyurethanes, UV curing adhesives, and others.
Another trend in structural adhesives is the substitution of fasteners, particularly in industries such as automotive manufacturing.
Rosin resin plays multiple roles in structural adhesives: it enhances adhesive strength, controls viscosity, improves water resistance, and enhances chemical resistance. Commonly used rosin-modified resins in structural adhesive formulations include pentaerythrite modified rosinate and rosin modified phenolic resin.
松香甲酯
CAS: 68186-14-1
SPECS: M305
松香甲酯由松香和甲醇酯化制得，具有低蒸汽压、高沸点、良好的导热稳定性等特点。并具备优异的表面润湿性能。被应用在胶黏剂、助焊剂、活性表面涂层和涂料等诸多领域。
氢化C5石油树脂
CAS: 71700-94-2
SPECS: H51150
C5聚合加氢精制而得的水白色热塑性石油树脂。主要用作增粘剂、连接料和增塑剂应用。由于其相容性能相比较传统C5石油树脂更具稳定，能够在高温下持久保持聚合物的内聚力强度，尤其适合热熔胶（HMA）、热熔压敏胶(HMPSA)、玻璃强化、汽车部件和高级橡胶制品。
氢化丙烯酸改性树脂
CAS: 144413-22-9
SPECS: HAR125220
氢化丙烯酸改性树脂HAR125220是一种无色透明的松香衍生物，只有采用独特的技术才能诞生。它具有高酸值和高软化点。HAR125220能够替代该种浅色松香衍生产品。
氢化松香
CAS: 65997-06-0
SPECS: H108
氢化松香由松香中枞酸型树脂酸的共轭双键在催化剂和一定温度、压力下，经部分或全部被氢饱和所得。氢化松香具有较高的抗氧化性能、在空气和光照下不被氧化和不变色、无结晶趋势、脆性小、粘结性强、能长期保持弹性和颜色浅且无特殊气味等优点，在工业上有广泛的用途。氢化松香钾皂和钠皂是合成橡胶的乳化剂，松香皂留在橡胶中可作活性填料，既是增塑剂又是增粘剂，同时也可作为天然橡胶和合成橡胶的软化剂；高度氢化松香可作为汽车…
