1.Improve the humidity of the operating environment and material surfaces. The lower the humidity, the lower the whitening phenomenon.

2.Control the amount of adhesive applied. Precise control of the amount of adhesive can be achieved using a dispensing machine to reduce adhesive overflow.

3.Improve ventilation. Maintaining good ventilation for the bonded parts before the adhesive is completely cured can significantly reduce whitening.

4.Use 460 methoxy series products for low odor and low whitening.

5.Use 4307 series UV/moisture dual-curing instant adhesive to perfectly solve the whitening problem.

How to deal with slow curing speed of instant adhesive?

Firstly, assess the impact of temperature and humidity on the adhesive. The lower the temperature and humidity, the slower the curing speed. Then, check if there have been any changes in the material.

PE (Polyethylene), PP (Polypropylene), PA (Nylon), TPU, silicone materials, and galvanized metal are not easily bonded. They can be bonded using surface treatment agents.

It can bond to painted surfaces, but it may corrode the paint. Since the bond is to the painted surface, the integrity of the paint should be considered. Smooth surfaces can also be bonded; better bonding results are achieved after sanding the surface.

Once fully cured, the adhesive is safe and non-toxic. Our products belong to the chemical category and are not recommended for direct use in areas that come into contact with food or beverages.

For automotive repairs, exhaust systems, etc., RTV silicone adhesive is recommended.
