Do you know the action of pressure sensitive adhesive thickener?

Pressure sensitive adhesive is a kind of adhesive that only needs to apply mild pressure and can be firmly bonded with the adhesive. Because pressure sensitive adhesive has certain initial viscosity and holding viscosity, no pollution to the adhesive surface after stripping, it has been widely used in electronic insulation, electronic component processing, color printing, automotive interior decoration and medical treatment and many other fields. However, in the actual application field, pressure sensitive adhesive will appear due to insufficient viscosity, resulting in the phenomenon of pressure sensitive adhesive degumming, therefore, manufacturers will add pressure sensitive adhesive thickener in pressure sensitive adhesive to adjust its viscosity and maintain stable liquidity at the same time, some manufacturers may be unfamiliar with pressure sensitive adhesive thickener, so let me introduce this thickener to you.

Use and composition of pressure sensitive adhesive thickener

Pressure-sensitive adhesive thickener is a thickener used for water-based acrylic copolymer without volatile organic compounds. It can be thickened quickly and add less, which is beneficial to help manufacturers save costs. It has excellent overall performance of thickening and leveling, and can also increase its viscosity at high shear rates, so that the product has rheological behavior similar to that of Newtonian fluid. Without chemical reaction with glue, it will also make the original performance of glue better. Does not affect the glue sticking relay, good stability, will not appear stratification phenomenon.

Advantages of pressure sensitive adhesive thickener:

1. High molecular weight, stable system after thickening, wide application range;
2. Simple to use, can be directly added to use, can obtain good thickening effect;
3. Good settlement and mildew resistance, excellent can opening effect, easy to use.
4. Has a good compatibility, and a variety of water-based resin system of good compatibility.
