Epoxy resin adhesive generally refers to the epoxy resin as the main body of the adhesive, epoxy resin adhesive generally should also include epoxy resin curing agent, otherwise the adhesive will not cure.
Epoxy resin adhesive is based on the epoxy resin and its characteristics are reprocessed or modified to make its performance parameters and other specific requirements, usually epoxy resin adhesive also needs to have a curing agent with it to use, and needs to be mixed evenly before it can be completely cured, generally epoxy resin adhesive is called A adhesive or main agent, the curing agent is called B adhesive or curing agent (hardener).
I. Epoxy resin glue is also divided into soft glue and hard glue
1、Epoxy resin soft glue: it is a liquid type, two-component, soft self-drying soft glue, colourless, transparent, elastic, lightly scratched surface will return to its original shape by itself. It is suitable for the decoration of polyester, paper, plastic and other signage.
2, epoxy resin hard glue: it is a liquid type, two-component hard glue, colourless, transparent, suitable for metal signs at the same time can be made all kinds of crystal buttons, crystal bottle caps, crystal wooden combs, crystal crafts and other high-grade decorative products.
2、Epoxy resin adhesive characteristics
1、 Basic characteristics: two-component glue, need to be mixed with AB, universal, can fill large gaps
2、Operating environment: room temperature curing, indoor or outdoor, can be mixed manually or use special equipment for AB glue (such as AB glue gun)
3、Applicable temperatures are generally from -50 to +150 degrees
4、Applicable to general environment, waterproof, oil resistant, strong acid and alkali resistant
5. Keep in a cool place away from direct sunlight, shelf life is limited to 12 months.
The epoxy resin adhesive is based on the epoxy resin and its characteristics are reprocessed or modified so that its performance parameters etc. meet specific requirements. Usually the epoxy resin adhesive also needs to have a curing agent with it in order to be used and needs to be mixed evenly before it can be fully cured.
The main characteristics reflecting the epoxy resin adhesive before curing are: colour, viscosity, specific gravity, ratio, gel time, usable time, curing time, thixotropy (flow stopping), hardness, surface tension, etc.
The main characteristics reflecting the cured properties of epoxy resin adhesives are: electrical resistance, voltage resistance, water absorption, compressive strength, tensile (tensile) strength, shear strength, peel strength, impact strength, heat deflection temperature, glass transition temperature, internal stress, chemical resistance, elongation, shrinkage, thermal conductivity, electrical induction rate, weatherability, ageing resistance, etc.
