FR-04 medium adhesive FR-04 is a water-based acrylic pressure-sensitive adhesive used for medium adhesive protective films. Compared with acrylic solvent based pressure-sensitive adhesives, it has the excellent performance of solvent based pressure-sensitive adhesives, as well as the characteristics of low cost and high solid content in the adhesive solution. It is an ideal environmentally friendly product.

2、 Characteristics of adhesive liquid

1. FR-04 pressure sensitive adhesive is a two-component lotion adhesive, which should be used together with aziridine curing agent. Different preparation ratios will make 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 surface pasting of aluminum profiles, PVC profiles, stainless steel plates, furniture, household appliances, signs, color plates, etc.

3、 Preparation and precautions of adhesive solution

1. Preparation:

In the case of mechanically stirring FR-04, 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.
