Dama Resin DM400

• DM-400 Water-based Dama Resin

Dama resin is a secretion of a borneol spice plant produced in Southeast Asia. It has a transparent light yellow to amber appearance. After esterification conversion, hydrogen bonds are retained, and special process treatment, it becomes an excellent binder for water-based coatings and printing inks.

• Applications

Special Features and Benefits：

Natural resin, polyol modified, low molecular weight, can achieve some requirements that cannot be achieved by monomer synthetic resin. After adding, it can increase the peeling force of ink, increase the cohesion of ink and the open time of ink, and solve the color difference problem of long-term printing of ink. It can be ground with color powder alone and then mixed with ink. It can be dispersed and ground with alcohol, water, pigment, dispersant and mixed solvent. Damar resin contains two hydrogen bond acceptors and four hydrogen bond donors. It has good adhesion on non-absorbent substrates.

• Recommended Use

Used in plastic inks, composite inks, and surface printing inks such as BOPP, PP, and PE to increase adhesion, fluidity, brightness, and drying speed, increase the re-dissolution performance of printed resins, and improve the miscibility and stability of resin emulsions. In particular, it has a certain firmness when used on untreated plastic films.

• Addition amount

According to the formula amount: 5%-10%

*. The above data are the dosage ratios in the formula. The optimal dosage needs to be determined through a series of tests.

• Instructions for use

DM400 is used as an auxiliary resin. Adding 5-10% to enhance adhesion can solve the following problems: good water resistance, high adhesion, high gloss, ປົງຄາຍ. It will not fade when scalded with 100-degree boiling water, and it will not fade when pulled with 3M tape.
