Product Design Thermo-Flex 750 is a technologically advanced, high solids, fire retardant, thixotropic, acrylic elastomeric coating uniquely formulated for the protection of polyurethane foam insulation.

Thermo-Flex 750 is designed to withstand the intense heat and ultra-violet rays of low humidity desert environments.

Product Use Thermo-Flex 750 is used as a protective coating over polyurethane foam.

Product Application Thermo-Flex 750 may be applied by medium nap rollers, brushes, or by conventional or airless spray equipment.

Airless spray application is most efficient whereas rolling or brushing may be used for touch-up, flashing and edge terminations or to fill voids, pinholes, holidays or cracks.

CONTACT LAPOLLA INDUSTRIES TECHNICAL SERVICE

PERSONNEL FOR SPECIFIC RECOMMENDATIONS,

PRICING AND AVAILABILITY OF SPRAY AND AUXILIARY

EQUIPMENT. Apply Thermo-Flex 750 only to clean, dry, sound surfaces, free of loose particles or other foreign matter.

A primer may be required subject to type and/or condition of the substrate. Consult Lapolla Technical Service Personnel for specific primer recommendations and substrate preparation procedures. Apply only to roofs that have adequate positive drainage (i.e. a minimum slope of 1/8 inch per foot).

Some separation may occur during shipment and storage, therefore the contents of each container should be thoroughly power mixed for ten (10) to fifteen (15) minutes before application. Thinning is not recommended. It is recommended that Thermo-Flex 750 be sprayed in multiple coats applied in multi-directional (north-south, east-west) passes to insure uniform film build and to avoid pinholing. Backrolling sprayed material may be necessary to fill pinholes in substrate. Final cured dry film thickness must be free of voids, pinholes, holidays, cracks or blisters.

Apply in a minimum of 2 coats with each coat at a maximum rate of 1.5 gallons per 100 square feet, for a total minimum coating rate of 3 gallons per 100 square feet. Additional coats of 1.5 gallons maximum per 100 square feet may be applied to obtain the desired final thickness of coating. The minimum allowable dry mill thickness shall be 24 mils. Granules may be broadcast into the final coating application at a rate of 35 – 40 pounds per 100 square feet. No foot traffic shall be permitted on the finished coated surface for 72 hours after application.

Processing Parameters Thermo-Flex 750 is a water-based elastomeric acrylic coating which will freeze and become unusable at temperatures below

32°F. PROTECT FROM FREEZING DURING SHIPMENT

AND STORAGE. Do not store material at temperatures below 50°F. Do not apply Thermo-Flex 750 when ambient air and substrate temperatures fall below 50°F or when there is a possibility of temperature dropping below 32°F within a 24-hour period after application.

Limitations and Precautions Do not apply over wet substrates or when inclement weather is imminent. Total cure of Thermo-Flex 750 requires complete evaporation of water. Cool temperatures and high humidity retard cure. Furthermore, all white or light colored coatings can cause a premature artificial dew zone during the curing process under certain climatic conditions. This is generated as the water in the coating evaporates, cooling the white surface and attracting moisture in the form of dew. Therefore, do not apply if climatic conditions prevent complete cure before rain, dew, or freezing temperatures.

Thermo-Flex 750 is not a vapor barrier coating and not recommended for use over most cold storage installations.

Where a vapor barrier is required, contact Lapolla Technical Service Personnel for proper selection and installation procedures.

General Safety, Toxicity, Health Data Material Safety Data Sheets are available on this coating material. Any individual who may come in contact with these products should read and understand the M.S.D.S. In case of emergency contact CHEMTREC EMERGENCY NUMBER at 800-424-9300.

WARNING: Avoid eye contact with the liquid or spray mist.

Applicators should wear protective clothes, gloves and use protective cream on face, hands and other exposed areas.

CLEAN UP: Water

EYE PROTECTION: Safety glasses, goggles, or a face shield are recommended.

SKIN PROTECTION: Chemical resistant gloves are recommended. Cover as much of the exposed skin area as possible with appropriate clothing.

RESPIRATORY PROTECTION is MANDATORY! Respiratory protective equipment, impervious foot wear and protective clothing are required at all times during spray application.

Contact Lapolla for a copy of the Model Respiratory Protection Program developed by API.

INGESTION: Do not take internally.

Consider the application and environmental concentrations in deciding if additional protective measures are necessary.
