Seven common problems with using universal adhesive in winter

Universal adhesive can bond many types of items, but due to low temperatures in winter, it often occurs that the adhesive curing is slow and the adhesive layer is not firmly bonded. Universal adhesive manufacturers have summarized common problems with the use of universal adhesive:

1、 Poor sealing: During adhesive application, the adhesive strip continuously breaks, the selection of sealant is incorrect, and insufficient consideration is given to gaps, temperature, etc. The adhesive layer is not fully cured.

2、 Disbonding: The coating is not completely cured, the coating is too thin, and the adhesive viscosity is too high. Poor surface treatment means excessive roughness. The parking time after surface treatment is too long.

3、 Misalignment: Improper placement and premature application of pressure. Premature heating causes the glue to flow.

4、 The adhesive layer is too brittle: the amount of curing agent is too large, the temperature is heated too high, and the curing speed is too fast.

5、 Coarse adhesive layer: The mixing of the adhesive is not uniform enough, and the adhesive may have deteriorated or failed, resulting in low temperature during coating.

6、 Adhesive layer sticking: The temperature is too low and the adhesive is not fully cured. It may be due to improper use or insufficient dosage of curing agent. It is possible that solvent based adhesives have a short drying time and overlap too early.

7、 Loose adhesive layer: The drying time of solvent based adhesive after coating is too short, and the adhesive layer is too thick at once, resulting in moisture on the surface of the adhesive.
