MAR-AK
 
 
CHARACTERISTIC PROPERTIES
 
MAR - AK is a water - based and self crosslinking, Vinyl - Acrylic Copolymer Emulsion, having 46 (%) solid content.

MAR - AK is generally used for the back coating applications of woven carpets. It is also recommended for textile finishing agent and for bonding Nonwovens - Needlefelt Type Carpets. During the application, the Self - Crosslinking is actualized in 3 - 4 minutes at a temperature 140?c. It gives clear, hard and durable film when completely dried.

PH (at 25°c) : 2 - 4
VISCOSITY (at 25°c) (Brookfield LVDV-1)  : 20 - 100 Cps (Sp.2/60 rpm)
MECHANICAL STABILITY : Positive
STABILIZING AGENT : Anionic - Nonionic.
PARTICLE SIZE : 0,2- 0,5 micron.
DENSITY (at 25° c) : 1,03 - 1,1 gr/ml.
GLASS TRANSITION TEMPERATURE  : + 23,7 ° c
FILM APPEARANCE : Clear, medium hard.
 
APPLICATION
 
MAR - AK is successfully used as Carpet backcoating. It is diluted with water at desired concentration. Vinyl Acetate Homopolymer type textile finishing agent can be added in to a mixture. Then the mixture is transferred in to a finishing trough. Later, the diluted emulsion is applied to the back of carpet with roller and passed through a drying tunnel at 130 - 140° c. During the drying, MAR - AK penetrates the back of carpet, produces film which it strengthens the binding of the knots.
 
STORING
 
MAR - AK is a water - based and Corrosive material, therefore, it should be kept in stainless steel, polyester containers or iron drums, plastic barrels with polyethylene innerlinings. It is sensitive to temperatures below + 5°c and above +35°c. It must be protected from freezing and direct sun light. It can be stored about six month under the recommended conditions.
