“THERMALBOND” – “EUROTBOND” #I, #II, & #III

THERMALBOND’S development was spurred by Williams Hayward’s interest in formulating economically and ecologically non-toxic, safe alternatives to solvent based epoxy and urethane systems, yet having automotive Acrylic gloss retention, Vinyl flexibility, Urethane abrasion and impact resistance all in a one single package. Generically, these coatings are derived from the melding of technologies of high molecular weight acrylic resins emulsified in water and emulsified rubber and vinyl latexes. The resulting polymers are extremely flexible, tough, and resistant to a vast variety of corrosive materials, while possessing superior gloss and color retention. THERMALBOND systems are single component therefore considerations such as pot-life, improper mixing procedures, flammability, pungent solvent odors, and hazardous waste disposal of spent coatings are virtually non-existent. THERMALBOND coatings also possess excellent humidity and salt spray resistances.

PARAMETERS FOR APPLICATION AND STORAGE OF THERMALBOND / EUROTBOND LATEX EXTERIOR FINISHES

THERMALBOND/EUROTBOND systems dry to recoat and stencil times are affected by temperature and humidity. For all waterbased products the higher the humidity, the slower the dry time, generally; the lower the humidity and the higher the temperature, the faster the dry times. To compensate for either situation, the choice of the proper tip and fan size is important. Wider fan sizes are suggested for humid conditions to assist I water evaporation. Narrower fan sizes and lower pressures are suggested in extremely hot temperatures to reduce over spray. The use of air assisted airless virtually eliminates overspray concerns.

1. Store coatings below 90 Deg. F. and above 40 Deg. F.
2. Do not apply to surfaces below 40 Deg. F. or above 90 Deg. F. Note: If surface temperatures are consistently above 90 Deg. F., severe dry spray will result. Solvent modifications may be necessary to insure proper aesthetics.
3. Apply under conditions such that surface temperatures are a minimum of 8 Deg. Higher than the dew point. THERMALBOND/EUROTBOND paints may be applied to slightly damp surfaces; however, the tendency to sag and flash rust is greatly increased, for the surface moisture mixes with the paint diluting it. Caution should be taken, and if it is absolutely necessary to paint a damp surface, a dust-coat, dry to touch, and second full coat approach should be performed.
4. Before exposing fresh paint to freezing temperatures, THERMALBOND/EUROTBOND should be completely dry to touch to ensure proper film formation.
5. Before exposing fresh paint to direct rainfall, THERMALBOND/ EUROTBOND should be dry for at least 5 hrs. @ 40F to ensure proper film formation. In general, water spotting may occur; however, this will disappear on exposure to sunlight. The disappearance of the whitish or milky look is a good indicator of film drying.
6. When re-coating THERMALBOND, the first coat must be dry to touch and free of visual signs of moisture, such as, angular blush or haze. If coated prior to this set up condition, a phenomenon known as “sliding” will occur; the second coat begins dissolving the partially dried first coat, creating a tear in the film to bare metal. Under extremely humid conditions, recoat times can be extended to three or four hours, from the normal 45 minutes to an hour.
7. A factor in drying water-based coatings is airflow. High velocity air helps remove moisture and increase set up times. This coupled with warm air can improve increase production rates.
