In our industrial production, for products requiring dispensing, we usually have to first understand its performance, and then choose the right glue. Often the performance is different, so will the glue we choose. Compared with organic silica gel, which type of epoxy resin sealant is better? Glue itself has no difference between good and bad, only because the choice of filling products, different performance, so will choose different glue.
First of all, we need to understand the characteristics of epoxy resin sealant and organic silica gel. Epoxy resin sealant can be used only when it is mixed with AB adhesive, and its versatility is strong. Epoxy resin sealant is cured at room temperature, and can be used indoors or outdoors. The applicable temperature is between - 50 and 150 degrees Celsius. It is waterproof, oil-proof, strong acid and strong alkali resistance, but it must be placed in places where the sun cannot shine. Generally speaking, the application of visual dispensing opportunities is very suitable for this glue.
Silicone gel and epoxy resin sealant have some similar characteristics, as well as high and low temperature resistance. Silicone gel has oxidation stability, weather resistance, flame retardant, corrosion resistance, non-toxic and odorless, and also has physiological inertia.
These two kinds of glue have many similarities in application, which are widely used in aviation, vehicle, machinery, transportation and other fields. Epoxy resin sealant is generally difficult to bond leather, wool fabrics and other materials, but it has good bonding ability in metal, ceramics, wood, cardboard, plastics, stone and so on. Silicone gel is widely used in food and medical industry because of its non-toxic, odorless, physiological inertia and other properties. It is not affected by ultraviolet light. It will be widely used in the selection of glue. If the medical industry chooses glue, it will usually choose silicone gel. The dispensing machines used in conjunction with these glues include visual positioning dispensing machines and accessories such as American dispensing syringes.
