Examination of FRP vacuum glue

There are different types of vacuum glue or membrane glue, generally vacuum glues are liquid and based on water solvent. For more than ten years, vacuum adhesive has been used to attach PVC covers or vacuum membrane covers to wooden sheets such as MDF and chipboard, however, in these ten years, the nature and quality of vacuum adhesives have changed in the direction of improvement. which we will briefly mention below.

The nature of vacuum glue
It might be interesting for you to know that vacuum glue or membrane glue has two generations:

First generation two-component vacuum adhesive
In this type of vacuum membrane adhesives, to activate the vacuum adhesive, a pressure of 4 bar atmosphere and a minimum temperature of 90 and a maximum temperature of 140 for 10 to 15 minutes were needed for vacuuming. For this pressure above 4 atmospheres, which must be created from above in the press machine, in order to neutralize this pressure, very strong jacks were needed, as well as a very strong body structure, and these press machines had a very high price, in terms of cost. The use of first generation vacuum adhesives was not economical. To use the first generation vacuum adhesives, a hardener is needed, which is combined with the two-component vacuum adhesive in a certain percentage, and in general, the only advantage of the first generation vacuum adhesive compared to the one-component vacuum adhesive is its higher thermal resistance.

Second generation single component vacuum adhesive
Single-component membrane vacuum adhesive or second generation vacuum adhesive is the adhesive currently used by vacuum cleaners. Second generation vacuum adhesives have many more advantages than their previous generation. It can be mentioned from the activation conditions of this series of adhesives to the level of efficiency, affordability, ease of use and reasonable price. These vacuum adhesives require less temperature and pressure to activate. In general, single-component vacuum adhesives can be considered a turning point in this industry.

Membrane adhesive properties
A good membrane adhesive or vacuum adhesive in standard conditions should have these features:

High thermal resistance

Good coverage

Quick drying

No bad smell

Moisture resistance

Cost-effectiveness

Uniform spraying

Strength on the sides of the work

High purity and no pollen

Can be used for all coatings
