Two, fat and PVC paste resin paste into the sizing, coated on glass fiber cloth, so that after baking, how do not shrink?
Diluent can also be added as a diluent substance is hydrocarbons, and their boiling point should be 100~200 degrees. But in any case, the boiling point of the diluent used should be lower than the dispersant. Some swelling effect of aromatics is on PVC resin, almost no Naphthalene Hydrocarbons, aliphatic hydrocarbon is not completely.
The auxiliary plasticizer can be added, and the dissolving capacity of the auxiliary plasticizer is relatively small, and when used, the viscosity is reduced and the storage is favorable.
Do not grind finer, the particles are too small at room temperature, often because of excessive solvent and paste viscosity high.
