Floor Temperature Polymer

Floor temperature polymer. Its low viscosity contributes to easy handling excellent substrate wetting and the development of strong bonds to a variety of substrates including damp concrete. Polymer family glass transition temperature oc approx pctfe 120 215 ptfe 130 ps 100 pmma 100 pvc 90 pet 70 pa nylon 50 room temp. Thus the net rate of polymer growth is zero. Low temperature epoxy l t e is a specially formulated 100 solids acrylated epoxy system designed to provide positive cure down to 20ºf and extremely rapid room temperature cure.

Ceiling temperature is a measure of the tendency of a polymer to revert to its constituent monomers when a polymer is at its ceiling temperature the rate of polymerization and depolymerization of the polymer are equal. Working time cure time viscosity mixing flow air release surface tension and pigment float will all be affected. This means that if your floor temperature is 45 degrees or lower coating the floor is a risk. This is why most technical data sheets will say not to coat a floor within 5 degrees of the dew point.

When this coating was dry in about 3 hours workers applied a pigmented coat of 75 solids polyaspartic advacoat and waited 45 minutes for it to cure. As you can see if the air temperature is 75 degrees and the relative humidity of the room is 35 the dew point would be 45 degrees. Is the temperature below which polymerization cannot occur. Generally the ceiling temperature of a given polymer is correlated to the steric hindrance of the polymer s monomers.

Interior and exterior tile installations have temperature requirements not for the material itself but for the thin set mortar and grout that is used to adhere. Specific grades and types will vary samples available polymers that have a tg less than room temperature are in the rubbery state at room. James hendley general polymers published in plant engineering june 1995 each different resinous flooring system placed on a concrete slab is formulated to withstand a specific type of environment. Above the ceiling temperature depolymerization will occur and the polymer will revert to its monomer.

Selecting polymers flooring systems by. 100 solids epoxies are dramatically influenced by temperature. Advantage recommends this material any time a floor has a moisture vapor emission rate greater than 7 pounds 1000 square feet 24 hours or if the floor will be washed down on a regular basis.
