Series Of Water Based Solid Resins For Varnishes OPV and prting Inks And Pigment grinding

Wangqin Solid acrylic resins suitable for producing various water based inks and varnish, ​OPV, pigment grinding, emulsion synthesis. Water based inks and varnish, ​OPV can be applied to paper board, food packaging, plastic packaging, cigarette packaging, pharmaceutical packaging and various film substrates, such as PE, BOPP, and PET. Wangqin Solid water based acrylic resin is provided in solid form and resinsis needed to neutralized and dissolved to form varnish before use.

Wangqin solid acrylic resins is designed to replace and as alternactive to Joncryl acrylic resin, SOLURYL acrylic emulsion products.

SUGGESTION OF DISSOLUTION
There are two kinds of equipments for dissolution of solid resins, reaction kettle and mixer, hence here are two sets of suggestions to dissolve the solid resins.

1. Reaction Kettle

Process:

1. Put the solid resin into the water in room temperature when rabbling at high speed;
2. Keep rabbling to ensure the resin is entirely moisted, it takes 5mins in this step normally;
3. Put the ammonia water into the kettle slowly;
4. Heat up to 70-80℃, then keep the temperature for 1.5 hours;
5. Rabble till the resin become entirely dissolved in the water, it takes more than 1.5 hours;
6. Make the PH 8.0-9.0, the ideal number is 8.5-8.7, ammonia water is used for PH adjustment.

Mixer

Process:

1. Put the solid resin into the water in room temperature when rabbling at high speed;
2. Keep rabbling to ensure the resin is entirely moisted at the speed of 1200r/min for 15mins;
3. Put the ammonia water into the mixer slowly: add 80%, then add the 20% after 30 mins;
4. Keep rabbling till the resin become entirely dissolved (around 4.5 hours), the speed could be lowered to 1000r/min in the second part of 4.5 hours;
5. Make the PH 8.0-9.0, the ideal number is 8.5-8.7, ammonia water is used for PH adjustment.
