Safety : Handle with care. Before and during use , observe all safety labels on packaging and paint containers ,consult HEMPEL Material safety data sheets and follow all local or national safety regulations. Avoid inhalation,avoid contact with skin and eye, and do not swallow.Take precautions against possible risks of fire or explosions as well as protection of the environment. Apply only in well ventilated areas.

HEMPATHANE TOPCOAT 55210

APPLICATION AND CRUING CONDITIONS : The surface must be completely clean and dry at the time of application, and its temperature must be above the dew point to avoid condensation. Minimum temperature for curing is -10℃/14℉. At the freezing point and below, be aware of the risk of ice on the surface which will hinder the adhesion. High humidity and /or condensation during application and the following 10hours(20 ℃/68℉) may adversely affect the film formation.

In confined spaces provide adequate ventilation during application and drying.

PRECEDING COAT: HEMPADUR 45141/45143,HEMPADUR MASTIC 45880/45881 or according to specification.

SUBSEQUENT COAT; NONE.

REMARKS: Certificate has been issued under the former quality number 5521.

Colours: Certain lead-free red and yellow colours may discolour when exposed to chlorine-containing atmosphere.

Leaded colours may become discoloured when exposed to sulphide-containing atmosphere. To obtain full opacity, an extra coat may be necessary, especially for certain lead-free colours ineg red ,orange, yellow and green.

Service temperatures: At service temperatures above 100 ℃/212℉,HEMPATHANE TOPCOAT 55210 will become more soft. Furthermore, discolouration may occur.

Film thickness: May be specified in another film thickness than indicated depending on purpose and area of use. This will alter spreading rate and may influence drying time and recoating interval. Normal range is 40-75 micron/1.6-3 mils.

Thinning : The type and amount of thinner depend on application conditions ,application method, temperature , ventilation ,and substrate. Thinner 08080 is recommended in general. Thinner 08510 may be used alternatively depending on local conditions.

Airless spray:5-15% thinning is recommended. Under extreme conditions up to more than 20% may be necessary to obtain satisfactory film formation.

The best result is obtained by applying a mist coat of HEMPATHANE TOPCOAT 55210 at first, and then 2-15 minutes later apply to full film thickness giving a uniform film formation. Do not exaggerate the film thickness.

Electrostatic spray: 10% thinning with specified thinner is recommended. Please contact HEMPEL for further advice.

*Faster drying and curing may be obtained by using an “accelerator”-consult HEMPEL for further advice.

A completely clean surface is mandatory to ensure intercoat adhesion, especially at long recoating intervals. Any dirt, oil, and grease has to be removed, e.g. with suitable detergent. Salts to be removed by fresh water hosing. To check an adequate quality of the surface cleaning a test patch is recommended before actual recoating.

Notes: CURING AGENT 95370is sensitive to moisture. Store in a dry place and keep the can tightly closed until use. Open curing agent cans with caution as overpressure might exist. Even small traces of water in the mixed paint will reduce the pot-life and result in film defects. HEMPATHANE TOPCOAT 55210 is for professional use only.
