The NL302D modified polyester resin launched by Shanghai Kangming Chemical Co., Ltd. can be cross-linked with amino resin. The paint film has excellent adhesion, good pigment wettability, a wide temperature adaptability range during curing, and can be cross-linked at low temperature, which is particularly suitable for fast line speeds.
Application characteristics:
The resin can be cross-linked with amino resin, the paint film has excellent adhesion, good pigment wettability, a wide temperature adaptability range during curing, low-temperature cross-linking, and can effectively reduce the use of acid catalysts and amino groups in the coating system, especially suitable for fast line speed.
Application range:
Coil coating primer and back paint
Technical indicators:
| Appearance | transparent |
| Solid content% | 58～62 |
| Color (Fe-Co) ≤ | 3 |
| Acid value (mgKOH/g) ≤ | 12 |
| Gardner viscosity (25℃) seconds | 15-25 |
Solvent dilution:
NL302D is soluble in esters, ketones, alcohol ethers and other solvents, and can also be soluble in some aromatic solvents. It has limited solubility in aliphatic solvents, and stability needs to be tested when used. Resin compatibility: It has good compatibility with epoxy resin, and miscibility and stability tests are required before mixing with other resins. This product has now entered the excellent material library. If you need a sample, please click: Kangming Chemical NL302D modified polyester resin.
