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.

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. |
