Causes and solutions of bubbles in glass bottles after high temperature painting

The main reasons for glass bottle temperature spray paint foaming are:


1. The film is in contact with water or exposed to a warm environment;


2, the solvent volatilizes too fast, the viscosity of the paint is biased;


3. The gas mixed in the paint is not released before painting;


4, some solid substances in the coating will automatically decompose and release gas, which can not penetrate the coating film and foam.

Glass bottle temperature spray solution:


1, paint in the construction do not contact with water, dry film should avoid long-term exposure in a wet environment;


2, the use of supporting solvents and diluents, paint viscosity to adjust moderate;


3, good to add alcohol solvents and defoaming additives.


4, the stirred paint should be cured for a certain period of time before construction.
