我发现玻璃胶已经干了，但我担心还会有甲醛释放。据了解，玻璃胶在固化过程中会放出刺激性气体，而且即使干透，也可能持续释放甲醛，需要一段较长的时间才能完全释放。

关于玻璃胶的凝固时间，我了解中性类型通常表面干燥需要2小时，而酸性类型可以在30分钟内凝固。但是要达到完全干透，则中性型需48小时，酸性型则为24小时。

对于使用硅酮胶进行修补，必须在它表面干之前完成，因为其固化过程是从外向里扩散的，不同特性的硅酮产品其表面干和完整固化所需时间各不相同。如果想要覆盖某个区域，用分色纸覆盖并确保在外皮形成前取走。

Glass glue's drying and curing process is quite fascinating. The adhesive can take anywhere from a few minutes to several days to fully harden, depending on the type of glue and the thickness of the application. For instance, an acid-based glass glue might dry in as little as 30 minutes, while a neutral one could take up to 5-10 minutes.

When it comes to using glass adhesives for repairs, it's essential to ensure that surfaces are clean and free of oils or other substances that might interfere with bonding. Acidic materials like metal should be wiped down with acetone before applying the adhesive.

Once applied, it's crucial not to disturb the surface until it has had time to cure completely. This can take anywhere from a few hours for thin applications up to several days for thicker ones.

The curing process involves chemical reactions between components in the adhesive mixture. As these reactions occur, heat may be generated which can cause nearby objects or surfaces to become warm or even slightly discolored.

In summary, while glass adhesives are incredibly versatile tools for DIY projects and home repairs alike – offering strong bonds between different materials – they require patience during their curing process so as not achieve optimal results without compromising safety standards around handling them safely throughout this duration period given by manufacturer instructions guidelines provided within packaging information supplied along side product purchase at store checkout counter display case shelf rack unit etcetera...
