Hychem PA Glaze 5 — Clear polyaspartic coating

Prior to the application, the substrate must be thoroughly prepared and coated.

• HYCHEM PA Glaze 5 is designed for application over other coatings, primarily applied to concrete substrates.
• Other coatings include, but are not limited to, HYCHEM epoxies, polyaspartics and polyurethanes which are recommended to form part of a complete system.
• If application as a clear coat over the substrate is required, consult HYCHEM for advice on suitable clear primers.

It is important to note that even when the application environment is warm, products which have been stored in cold or cooler conditions should be pre-conditioned, ideally to 20-25°C.

In a clean container, mix PA Glaze 5 Part A Resin and Part B Hardener at 1:1 by volume or weight using a mechanical stirrer at slow speed to minimise air and moisture incorporation. Move the mixer around from side to side and top to bottom and scrape the sides of the mixing vessel to ensure thorough mixing. If dilution is required, add xylene after mixing Part A and Part B for 45 seconds and then mix for a further 45 – 60 seconds. Total mix time should be 90 – 120 seconds.

Apply by brush and roller at a rate of 3 – 7 sqm/litre depending on surface porosity. Hychem PA Glaze 5 can be applied at approx. 4 sqm/litre in one coat over standard flake. High humidity will reduce work time, tack free time and curing rate. PA Glaze 5 can be diluted up to 15% with xylene (HYCHEM Solvent X).

Temperature and the surrounding atmospheric conditions will play a part in the curing process of all resin products. Under conditions of low temperatures and high humidity the final cured surface finish can be adversely affected, potentially resulting in poor gloss retention, discoloration over time, poor overcoat ability and inter-coat adhesion. Quite often these conditions will result in the formation of a white film over the surface, often evident after contact with water. If this occurs, the existing coating will need to be abraded to completely remove the affected surface to ensure the adhesion of subsequent applications. In some cases, partial or complete re-priming may be necessary. Attention also needs to be paid to the substrate temperature, which should be at least 3-5 °C above the dew point during the curing phase. Industry standards recommend the accurate recording of environmental conditions such as substrate and air temperatures, humidity levels and dew point readings during both the application and curing processes. Full material warranties cannot be provided unless all the relevant data has been recorded accurately. If in doubt consult the HYCHEM technical department for advice.

Polyaspartic polymer products may cause allergic reactions through skin contact. Goggles and protective gloves and clothing should always be worn. Ensure that there is adequate ventilation and air flow and avoid breathing the vapour. If skin contact occurs, wash skin with soap and water. If eye contact occurs, wash immediately with copious amounts of clean water.

24 months from date of manufacture, stored under shelter at 23 °C in the original un-opened container.

The packaging must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between 5°C and 30°C.

HYCHEM PA Glaze 5 is a clear coating with excellent UV resistance. It is non-yellowing and high gloss.

• High humidity will reduce work time, tack free time and curing rate.
• PA Glaze 5 can be diluted up to 15% with xylene (HYCHEM Solvent X).
• If application as a clear coat directly over the substrate is required, consult HYCHEM for advice on suitable clear primers.
