硅胶粘的好,底涂剂少不了

Recommendations for NuSil’s Primers

粘合性是涉及硅树脂材料的众多应用的关键性质

有机硅底漆通常用于改善有机硅和各种基材之间的粘合性。
硅氧烷底漆的正确处理和应用可以增强粘合剂的整体强度和一致性。
建议采用以下步骤以获得最佳粘合效果:
储存和处理倾倒使用量。

丢弃未使用的底漆。

不要放回原装容器中。
容器在不使用时应保持密封

底漆将在大气湿气存在下水解
建议
用干燥气体(如氩气或氩气)填充容器中的空白处在密封容器(原始或二级容器)之前的氮气

白色固体的出现表明底漆水解并且不再有助于粘合。

Adhesion is a critical property for numerous applications involving silicone materials. Silicone primers
are often used to improve adhesion between silicones and various substrates. The proper handling and
application of silicone primers can enhance the overall strength and consistency of bonds. The following
procedures are recommended for best bonding results:
Storage and Handling
Pour out amount needed for use.
Discard unused primer. Do not place back in
original container.
Containers should remain sealed when not in
use. The primer will hydrolyze in the presence of
atmospheric moisture.
It is recommended to fill empty space in the
container with a dry gas, such as argon or
nitrogen, before sealing container (original or
secondary container). The appearance of white
solids indicates that the primer is hydrolyzed
and will no longer aid in adhesion.

推荐材料/条件


手套 - 处理零件时使用乙烯基或丁腈手套。
已知乳胶手套会引起硅酮的固化抑制,其中手套与待涂底漆的表面接触

这适用于铂固化(也称为附加固化)有机硅。


清洁剂 - 建议使用电子级异丙醇(IPA),因为它不会留下残留物并迅速蒸发


泡沫湿巾 - 使用洁净室擦拭布。避免使用可能含有灰尘,油和纤维的湿巾。

这些物质会干扰引物反应。


溶剂 - 通常为VM&P石脑油或二甲苯(NuSil的R-1001)。


通风 - 使用易燃材料时应用标准安全程序

Recommended Materials / Conditions
Gloves - Use vinyl or nitrile gloves when handling parts.
Latex gloves are known to cause cure inhibition of silicone
where the gloves come into contact with the surface to be
primed. This applies to platinum cure (also known as Addi-
tion Cure) silicones.
Cleaning Agent - Electronic grade Isopropylalcohol (IPA) is
recommended as it does not leave residues and evaporates
rapidly.
Foam Wipes - Use clean-room grade wipes. Avoid using
wipes that may contain dust, oil, and fibers. These items can
cause interference with the primer reaction.
Solvents - Typically VM&P naphtha or xylene (NuSil’s
R-1001).
Ventilation - Apply standard safety procedures when working
with flammable materials.
