快速固化医用胶水指南

Fast-Cure Silicone Adhesives

NuSil的快速固化有机硅粘合剂系列是两部分,铂催化的加成固化体系,具有优异的机械性能,包括高剥离强度。

无限制粘合剂(MEDX-4213)可考虑用于长期植入(> 29 天)医疗器械应用,限制粘合剂(MEDX-4013)可用于短期植入(<29天)或外部申请。

这些粘合剂通常用于将有机硅粘合到金属,塑料,聚氨酯,陶瓷,玻璃或其他有机硅上 - 通常不使用底漆。
虽然每种产品都可以通过加热来快速固化,无论是通过加热灯,热风枪还是在烤箱中,一些粘合剂都经过独特设计,可在室温下在24小时内固化(参见下表)。

与其他固化体系不同,这些配方不需要环境水分来固化。

该固化体系不会释放醇副产物或腐蚀性酸,这些常见于其他有机硅粘合剂固化机制。

所述可行的稠度使产品从一个被容易地分配无气侧由端试剂盒,消除了与混合和除气的困难。
MED3-4213和MED3-4013是该产品系列的最新成员,具有更长的工作时间(最少60分钟),同时仍在室内固化24小时内的温度

NuSil’s line of fast-cure silicone adhesives are two-part, platinum
catalyzed, addition cure systems that provide excellent mechanical
properties including high peel strength. The Unrestricted adhesives
(MEDX-4213) may be considered for use in long-term implantable (>29
days) medical device applications, and the Restricted adhesives
(MEDX-4013) may be used for short-term implant (<29 days) or external
applications. These adhesives are typically used to bond silicones to
metals, plastics, urethanes, ceramics, glass or other silicones – frequently
without the use of primer.
While each product is designed to cure rapidly with the application of heat,
either by a heat lamp, heat gun, or in an oven, some of the adhesives are
uniquely designed to cure in less than 24 hours at room temperature
(reference table below). Unlike other cure systems, formulations such as
these do not require ambient moisture to cure. This cure system does not
release alcohol byproducts or corrosive acids, which are often
encountered with other silicone adhesive cure mechanisms. The
workable consistency allows the products to be easily dispensed from an
airless side-by-side kit, eliminating difficulties with mixing and de-airing.
MED3-4213 & MED3-4013 are the latest addition to the product line
having a longer work time (minimum 60 minutes) while still curing at room
temperature in 24 hours
快速固化医用胶水

符合USP VI级的广泛生物相容性测试,并选择ISO-10993测试要求。
已向美国食品和药物管理局提交了每种产品的主要访问文件(MAF)。

有兴趣参考MAF的客户必须直接联系NuSil。
基材考虑虽然这些粘合剂与生物医学组件常见的大多数材料接触固化,但例外包括硫磺固化有机橡胶,乳胶,氯化橡胶,一些RTV硅酮和一些固化剂的未反应残留物

某些应用可能需要使用底漆。

Each product is supported with extensive biocompatibility testing
conforming to USP Class VI and select ISO-10993 testing requirements.
Master Access Files (MAFs) for each of these products have been filed
with the U.S. Food and Drug Administration. Customers interested in
authorization to reference the MAFs must contact NuSil directly.
Substrate Consideration
While these adhesives cure in contact with most materials common to
biomedical assemblies, exceptions include sulfur cured organic rubbers,
latex, chlorinated rubbers, some RTV silicones and un-reacted residues of
some curing agents. Some applications may require the use of primer.
