FR-09 is a water-based acrylic pressure-sensitive adhesive used for medium to high viscosity protective films. In addition to the excellent performance of solvent based pressure-sensitive adhesives, it also has the characteristics of low cost and high solid content of adhesive. It is suitable for frosted profile protective films and is an ideal environmentally friendly product.

2、 Characteristics of adhesive liquid

1. FR-09 pressure-sensitive adhesive is a two-component product that should be used in conjunction with aziridine curing agent. Different formulation ratios will result in different adhesive protective tapes.

2. Good aging resistance (including high and low temperature resistance, high humidity resistance), and good UV resistance.

3. Recommend using PET, OPP/PET composite substrates, and PE substrates as protective films.

4. Suitable for frosted profile surfaces.

3、 Preparation and precautions of adhesive solution

1. Preparation:

In the case of mechanically stirring FR-09, slowly add a quantitative curing agent that has been diluted with an appropriate amount of water. After adding the curing agent, ensure to stir for 5 minutes to evenly disperse it in the adhesive solution, and filter it through a 200 mesh filter.

2. Precautions

① The safe use period of the adhesive solution for preparing curing agents generally does not exceed 6 hours;

② The product should avoid freezing and exposure to sunlight, with storage conditions of 5-35 ° C and an effective storage period of 6 months.
