Usage
Paint materials used to prevent lead from sticking when soldering parts on printed circuit boards for information, communication, and display
Process of processing to provide electrical insulation while protecting circuits other than parts holes or surface mounts (SMDs) soldered to the final product
Resist Ink to protect surface circuits from external environments while preventing unnecessary lead adherence when inserting and mounting parts into PCB and COF
Characteristic
A product with high surface hardness and excellent flexibility through curing between polyurethane resin synthesized with a molecular weight designed for the purpose and epoxy resin with excellent electrical insulation
It consists of a clean system from the input of raw materials to the packaging of the product, so there is less oreign substances
Using a fine size pigment, there is no poor pigment dispersion or oversize particle size
How to use
Add 110g of curing agent exactly to 690g of main agent.
Stir at 660 rpm x rev. of rotation of paste mixer (Rot.).
It should be used within 24 hours after aging for at least 2 hours.
