Pressure sensitive adhesive, AD- 920, is an acrylic copolymer which contains carboxyl groups. Long time adhesion characteristics of this product has resulted in widespread application of this product in adhesive industry.
Details
- miscible with a wide range of nonionic and anionic aqueous polymers.
- compatible with Glycol ethers and Phethalate ester and Benzoate types.
- compatible with Acrylic Acid-based, Polyvinyl alcohol ,Cellulose ethers and Poly urethane thickeners.
- compatible with different types of Coalescence agents, such as Texanol, 402 solvent, Diethylene glycol monobutyl ether.
- final coating made by this product represent resistance to peeling and offers suitable adherence to slim layer of the surface underneath and at low temperature as well.
provides great adherence on plasticized/ unplasticized PVC, polyesters, polyolefin films, sealants , OPP/ BOOP films, PET and etc.
6 month from production date under standard conditions and away from freezing, direct sunlight and heat.
While using AD- 920, according to the usage, the film formation temperature can be decreased by coalescence agents and by using thickeners reach to the suitable viscosity. Using anti foam to the level of 0.1 to 0.3% when using this is necessary and in order to prevent of microorganisms attacks suitable preserver should be used.
Using of glycols leads to resistance against freezing increases but altogether the film formation temperature will not decrease noticeably.
