Description

L-8469 is a specially modified UV polyurethane resin containing hydroxyl groups, which can react with isocyanates to form dual-cure coatings. It provides good adhesion to plastic substrates such as PC, ABS, and PET. L-8469 can be used both as a modifier for UV coatings and as the primary resin in dual-cure UV coating formulations.

Technical data

Product Features

Fast surface drying, suitable for vacuum forming

Low shrinkage, high hardness

Good resistance to steel wool

Applications

Dual-cure varnishes for various plastics, dual-cure UV inks, and dual-cure UV resins for hardness enhancement.

Curing Process

Coating → (100-120℃) * 3 minutes constant temperature baking for surface drying → Vacuum forming → UV curing (800-1200mj/cm²) → Finished product performance testing

Precautions

1.Ensure that the UV coating absorbs sufficient ultraviolet energy to achieve complete curing; insufficient curing may adversely affect the coating performance.

2.Do not pour any remaining material back into the original container. Keep it tightly sealed, protected from light, and stored at room temperature.

Storage Conditions

To prevent polymerization or gelation caused by the high reactivity of this product, keep the container tightly sealed and store it away from heat sources and direct sunlight. The recommended storage temperature is below 30 °C. Reseal the container promptly after each use; do not leave it open to the air. Under normal conditions (25 °C, well-ventilated environment), the product remains stable for up to 6 months.25 KG / 200 KG per drum.

Tips: L-8469 features rapid surface curing, excellent thermoformability, and superior resistance to abrasion from steel wool.
