Hempatop Direct 460 LH

Description

Hempatop Direct 460 LH is a high solids, low HAPS, two-component, polyamide cured epoxy coating. It forms a tough, hard-wearing coating with good resistance to water and petroleum products. It has excellent resistance to UV exposure, and exhibits excellent gloss and color retention for exterior applications when compared to traditional epoxy coatings.

Recommended use

For exterior or interior applications on the rail cars as one coat DTM application. As one coat, self- primed, surface tolerant coating in heavy duty long term protection of steel pipes and other structural materials under severe service conditions. Recommended where low VOC and low HAPS are desired.

Hempatop Direct 460 LH is a high solids, low HAPS, two-component, polyamide cured epoxy coating. While delivering excellent protection against corrosion, it is uniquely formulated to combat color and gloss fading.

A resilient, high gloss coating that gives you the best performance in the most challenging conditions with an enhanced appearance that is proven to last.

This new innovation in epoxy coatings:

Chalks to original color for extended aesthetics and color retention,
extends initial high gloss,
applies with ease, equating to less rework an quicker throughput,
offers excellent UV and chemical resistance.

Meeting environmental regulations and lowering the use of ozone depleting solvents without compromising performance is key. With that in mind, we developed Hempatop Direct 460 Low HAPS for railcar applications, this advanced formula uses the very latest technology and uniquely, chalks to original coating color, keeping your railcar assets looking their best for longer.

Meeting our customers’ demands for ever more robust coatings, we have developed high performance Hempatop Direct 460 LH.

This advanced formula uses the very latest coating technology and uniquely, chalks to original coating color, keeping your railcar assets looking their best for longer.

Hempatop Direct 460 LH is a one-coat, direct-to-metal (DTM) epoxy that dries quickly to a resilient, long wearing high gloss finish to protect rail assets from corrosion and ensure long-term color performance that gives:

Resilient gloss finish,
chalking to original color,
enhanced color retention,
ease to apply,
fast drying.
