Field of application
Foam is used for installation of doors and windows, insulation and fixation of tubes, filling of holes and gaps, fixation of wall panels and roof stones, and for thermal insulation.
Winter Foam-Straw Application
One-component polyurethane foam for winter is an air humidity curing prepolymerized mixture in an aerosol can. Cured foam is a good temperature and sound insulator, and has strong adhesive properties. Adheres well to most building materials, with the exception of Teflon, polyethylene and silicon surfaces. Cured foam is sensitive to UV-light and direct sunlight.
Storage Regulations
Can contains diphenylmethane 4,4-diisocyanate. Dangerous when inhaled. Irritates eyes, skin and respiratory organs. Inhalation of gas may cause allergy. In case of eye-contact rinse thoroughly with water and seek medical help. Do not smoke during work! Make sure that there is good ventilation, use protection means when necessary. Keep out of the reach of children. Detailed safety information is available on safety data sheet (SDS).
Application Instruction
Hold the foam can in upright position. Screw the applicator (straw) to the foam can valve. Shake the can at least 20 times before use. For application, turn the applicator upside down and press the applicator trigger. The foam output can be adjusted by applicator trigger. At low temperatures foam can must be warmed before work in warm room or water. Temperature of room or water must not exceed +30 °C.
Application Conditions
Luchttemperatuur tijdens applicatie -10 ° C ... + 30 ° C de beste resultaten bij 20 ° C . Kan de temperatuur tijdens applicatie 10 ° C ... + 25 ° C de beste resultaten bij 20 ° C . Oppervlakken moeten vrij van stof, losse deeltjes en olie voordat schuim wordt toegepast. Ondergrond moet worden bevochtigd als het schuim expandeert als gevolg van het vocht . Een bevochtigde oppervlak zorgt voor betere resultaten . Uitgehard schuim kan worden geschilderd
Storage Conditions
Can must be stored and transported in vertical position. Store in a cool and dry place. Store at temperatures +5 °C…+30 °C. Aerosol can must not be stored at temperatures over +50 °C and in direct sun. Storage life 12 months.
Cleaning
Uncured foam can be removed with acetone, cured foam only mechanically.
