What is the use method of silicone pressure-sensitive adhesive without affecting the viscosity?

Dec 04, 2019

In the process of how to use the silicone pressure-sensitive adhesive, if it is used improperly, it will reduce its stickiness. So how can the silicone pressure-sensitive adhesive be used without affecting the viscosity? Next, the silicone pressure-sensitive adhesive manufacturers will introduce you to this knowledge, and follow this article to find out.

1. The user should appropriately adjust the mixing ratio of the silicone pressure-sensitive adhesive according to the type of substrate, coating thickness and climate conditions (ambient temperature, humidity). In high-temperature and high-humidity climatic conditions, users should increase the ratio of silicone pressure-sensitive adhesive and curing agent by about 5% to 10%.

2. The surface of the substrate to which the silicone pressure-sensitive adhesive is bonded needs to be clean and dry without dust and oil.

3. Pay attention to check and control the viscosity of the adhesive during the coating process of the silicone pressure-sensitive adhesive; it must have a sufficient coating amount and be fully cured.

4. The coating of silicone pressure-sensitive adhesive must be well-suited for the environment. It is recommended that the operation workshop adopt dust-free processing, temperature control at 25-35 ° C, and humidity control at 15-60%. Too much dust will lead to increased defects. Too low temperature will cause poor leveling and decreased adhesion. Too high humidity may cause shrinkage of the coating film. Too low humidity may cause hidden dangers to static electricity and whitening of the surface.

5. The prepared silicone pressure-sensitive adhesive should be used up within 1 hour as much as possible. If it is found that the viscosity of the adhesive is significantly increased or gel appears, it should be stopped.

6. Please pay attention to ventilation when using the silicone pressure-sensitive adhesive after mixing, and wear appropriate labor protection tools. Keep away from fire, high temperature and static electricity.

7. Please read the product safety instructions before using silicone pressure-sensitive adhesive.
