Heat conductive glue is most often used for attaching a cooler heatsink to a processor or memory, mounting LEDs, and other parts to a heatsink in cases where the use of thermal paste and fasteners is inappropriate or impossible.
Product description
Externally, thermally conductive glue looks like a viscous glue-like mass of white color of homogeneous consistency with almost no smell. It is sold in a tube with a screw-on plastic cap, which prevents air from entering the tube and allows you to keep the glue in liquid form. When using for the first time, it is necessary to pierce the special protective coating on the tip of the tube. When reused, the cap easily unscrews to expose the adhesive.
Glue is used to connect fast heating parts on a heat-conducting radiator.
Advantages of glue
Strength and density during drying are also among the positive qualities possessed by thermally conductive adhesive "Alsil". Absolute adhesion of the adhesive to the surface ensures a secure connection.
Heat-conducting glue "Radial" is sold in a sealed airtightpackaging that provides protection from drying out for a long period of time. Such packaging increases the shelf life of the adhesive. This is very convenient, because you do not have to buy a new tube every time without using the old one to the end. This is the undeniable advantage of "Radial" in comparison with products manufactured by other manufacturers.
In terms of its technical characteristics, this heat-conducting adhesive is similar to Alsil.
To dismantle the component attached to the heatsink with this adhesive, use a knife to gently pry the required part and remove it, then repair or replace.
Heat-conductive heatsink adhesive has proven to be a reliable and versatile tool for mounting even the most powerful LEDs and other parts.
How to apply heat transfer adhesive?
The process of mounting diodes with glue consists of several stages:
- Degrease all surfaces you will be working on with alcohol or acetone.
- Apply a small amount of thermally conductive adhesive to the surface of the part to be cooled.
- Using force, press the part to be cooled against the surface and try to make progressive circular motions to evenly distribute the adhesive over the entire surface of the part to be cooled on the radiator.
- Fix pressing for 3-4 minutes for better adhesion.
- Let the mixture dry. Glue hardens in 20 minutes, but complete drying occursonly in a day.
Do-it-yourself hot melt adhesive?
You can even create an adhesive that conducts heat with your own hands. In this article, you will find simple but effective tips on how to make your own heat-conducting adhesive if you don’t have a special tool. So, what is the best way to attach parts to a heatsink without damaging the system (it is important that thermal conductivity is maintained)?
To get a high-strength thermally conductive adhesive, you need to combine 25 ml of glycerin and 100 g of lead oxide. Water from glycerin is evaporated by heating the mixture to a temperature of 200 degrees Celsius. Lead oxide powder is also heated for several minutes, while maintaining a temperature of 300 degrees Celsius. Only after such manipulations, the components are mixed. The result is a pasty paste that is formed by a chemical reaction.
Another easy way to attach diodes to a heatsink is to mix epoxy and thermal paste. But there are cases when the use of thermal paste is inappropriate, then it is better to use specially prepared or purchased hot melt adhesive.
