Description

L-6367-5 is a trifunctional UV polyurethane modified with a polycarbonate backbone, offering excellent weathering and yellowing resistance. It is primarily used in excimer UV skin-feel coatings requiring high yellowing and weathering resistance. On white substrates cured at 500 mJ/cm² with repeated exposures, the resin exhibits a Δb ≤ 0.2. When activated under short-wavelength excimer UV spectra (172 nm, 222 nm, 254 nm), it forms a fine, soft, elastic matte finish with excellent scratch resistance.

Precaution & Storage

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

2.Do not pour unused material back into the original container. To prevent premature polymerization due to the high reactivity of this product, keep it tightly sealed and store away from heat sources and direct sunlight. Recommended storage temperature: ≤30°C. Unused portions should be sealed promptly and not left open. Under room temperature (25°C) and ventilated conditions, the safe shelf life is 6 months.

Packaging: 25KG / 200KG per drum

Tips:L-6367-5 offers excellent compatibility, high softness and elasticity, and fast curing speed. The use of mono- and difunctional monomers allows easy adjustment of wrinkle formation speed and size.
