Description

UC 699 polyurethane coating is a solvent free, two-part polyether-based coating. It yields an extremely flexible hi-build product with good chemical resistant and elongation properties.

Application

Mix the activator and the base separately before adding the activator to the base and mixing thoroughly for a minimum of 3 minutes with a paddle mixer.

Apply a thin coat of primer by brush and allow the solvent to evaporate before applying coating or sealant.

Once the primer loses its tackiness, re-prime.

The self-levelling grade may be applied ion a single application by notched trowel or rake and rolled with a spiked roller to assist in the levelling process as well as to remove bubbles.

Walls and sloping areas should be coated with the thixotropic grade using a brush or roller. Note two coats are recommended and the intercoat time must not exceed 24Hours.

Surface Preparation

The correct preparation of the surfaces is critical.

All surfaces should be clean, sound, and dry, and all laitance or surface contamination should be removed by wire brushing, grinding or grit blasting.

Vacuum or blow with compressed air to ensure total removal of dust.

On masonry substrates, UC 695 is recommended.

Product Application

It is used as a seamless flexible waterproofing and chemical resistant coating in containment or bunded areas where crack bridging of the substrate is essential.

Cleaning

Clean all tools immediately after use with UC 901.

Once the material has polymerised it may only be removed mechanically.

Safety

Contains isocyanates.

Ensure adequate ventilation.

Do not use in confined spaces.

Ensure adequate ventilation and the absence of any ignition source.

Wear protective clothing.

In case of eye contact wash well with water and obtain medical advice.
