How long does the crystal glue dry? Crystal glue quick solidification method

November 6th, 2023

Crystal glue, also known as crystal drop glue, according to the different raw materials used, is divided into two categories: polyurethane PU glue, epoxy resin AB glue, epoxy resin type is relatively cheap and widely used, but yellowing resistance and toughness are relatively poor, and polyurethane PU glue has anti-ultraviolet function, which can ensure no yellowing for three years. It does not harden over time and has good toughness. It is suitable for high-end products such as vehicle signage that are used more outdoors, but it is used less because of its high price. Epoxy crystal glue commonly used in industry is composed of high purity epoxy resin, curing agent and other modified materials. After solidification, it also has the characteristics of water resistance, high temperature resistance, yellowing resistance, chemical corrosion resistance, crystal clear.

1、 the solidification time of crystal glue
Crystal glue in the process of use is susceptible to the influence of temperature solidification time will be appropriate to extend or shorten, normal temperature (25℃) after the general operation of the solidification time in 3-4 hours or so, winter due to different regions of the temperature is inconsistent, solidification time is about 5-8 hours; Of course, if the temperature is higher (100 ° C).

2、crystal glue fast drying/fast solidification method
First of all, the crystal glue is stirred, defoamed and glue dropping according to the normal product ratio recommended by the manufacturer at the factory.
Crystal glue quick drying method at room temperature:

1. The common method is to put the product on the crystal glue, put it in the industrial oven, bake it below 30 degrees for 1-2 hours, and then heat up to 60-80 degrees, bake for 2-3 hours;

2. Rapid solidification method of winter crystal glue: rapid solidification method of winter crystal glue and precautions for use;

3. Change the formula of A glue or B glue in crystal glue. This method is suitable for personal DIY use, and is not recommended for industrial products (because it will affect the stability of the product in the later stage).

Winter crystal glue rapid solidification method and use precautions

What is the reason why the epoxy AB glue does not cure completely for a long time after dropping?
