Description

UC 101 is a two-component clear epoxy primer which has been designed as a high-performance bonding agent for use in conjunction with UC polyurethane and epoxy compounds where maximum adhesion to porous substrates is essential. Its low viscosity allows for deep penetration into porous substrates and its high solids content ensures bonding even when subjected to immersion in water.

Application

Mix base and activator thoroughly and apply the mixed material with a brush or roller to ensure complete coverage.

Particular attention should be paid to any voids and hollows.

Allow at least 30 minutes for the solvent to evaporate before applying the topcoat.

If after 3 hours or once the primer has lost its tack, re-prime before applying topcoat.

Protect the primed surface from dust or dirt, which could settle and interfere with the adhesion of subsequent coats.

Surface Preparation

Correct preparation of the substrate 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 removal of dust.

Product Application

To act as a primer for UC epoxy and polyurethane compounds when applied to porous or friable surfaces such as concrete or plaster or when water immersion or dampness is anticipated.

Cleaning

Clean all tools with UC 901 before the primer has cured as it is almost impossible to remove once this has occurred.

Safety

Contains organic solvents.

Flammable.

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.
