Tackifier for Elastomers
Tackifiers are employed in elastomeric compositions to produce wider practical ranges for elastomer properties such as stiffness and tack. AUROTACK 202 has been developed to improve adhesion and sometimes cohesion without necessarily stiffening or softening the elastomer compositions.
For various applications, it is desirable that elastomers have good tack properties prior to curing. The tack property should be to allow the elastomer to bond on contact with a force, which is sufficiently high to oppose delaminating forces which appear enough during the fabrication of elastomers products.
AUROTACK 202 is particularly useful in elastomer products which require green tack in their construction. these elastomers include natural rubber (NR), poly butadiene rubber (PBR), ethylene propylene diene copolymer rubber (EPDM), butadiene-styrene copolymer rubber (SBR), acrylonitrile copolymer (ABS) etc. AUROTACK 202 does not have any adverse effect on the cure rate of the vulcanisation.
APPLICATIONSAUROTACK 202 may be used in elastomers as tire stock tackifier, cement tackifier and tackifier for any rubber application requiring green tack. Rubber products that require good green tack in their construction include tyres, belts, hoses and tread rubber. These tackifiers may also be utilized in rubber based adhesives containing SBR, NR, EPDM, NBR etc both of the solvent and the emulsion type
