1. Viewfoam caulking agentThe internal structure and shape of the internal bubble. After cutting the foam, look at the cross section. If the pores are uniform and small, it is a good foam; ifpores is very large, indicating that the density is not good, it is easy to collapse, and it is a defective product.

2. Observe polyurethanefoam caulking agent‘s foam surface, a good foam surface will be groove-shaped, smooth but not particularly bright; a bad foam surface will be flat and not folds.

3. Watchpolyurethane foam caulking agent glue outeffect. When foaming, check whether the sprayed foam is smooth and not too thin or too thick. If the foam is too thin, the foaming is too small, and the fluidity is toofast, the construction is difficult and the bubbles are easy to collapse.

4. Spray polyurethane on the newspaperfoam caulking to form a layer of foam material. The next day, check whether both ends of this layer of foam material are tilted. If it tilts, it means that the foam has shrunk. The higher the tilt, the more severe the contraction. If there is no tilt at both ends, it means that the foam performance is stable.

5. Press the foam with your fingers. If the foam is elastic, it is a good foam;poorFoam is inelastic, difficult to press, and brittle; observe the polyurethane foam adhesive on the base Material adhesion. Good foam has strong adhesion to various substrates, while poor foam adhesionWeak.
