Sulphur modified          
Butaclor SC 10 35 - 51 Very slow Yes No

Sulphur modified Butaclor grades display high building tack and high tear and flex resistance. SC10 and SC22 are suitable when high bonding and high building tack on fibers and textile are required. SC202 displays high properties and high heat resistance. SC132 is specially suitable for dynamic properties, Tear and flex resistance improved at low and high temperatures
Butaclor SC 132 35 - 51 Very slow Yes No
Butaclor SC 22 35 - 51 Slow Yes No
Butaclor SC 202 37 - 53 Slow Yes No
Mercaptan modified          
Butaclor MC 10 41 - 51 Very slow Yes No

Mercaptan modified Butaclor grades allow better compression set and temperature resistance.

Butaclor MC 10 and MC 20 are particularly suitable for the manufacturing of rubber goods withgood resistance to crystallization.

Butaclor MH 30 and MH 31, high viscosity grades, can accept more fillers and plasticzer, and therefore reduce compounds cost.
Butaclor MC 20 41 - 51 Slow Yes No
Butaclor MC 30 41 - 51 Medium Yes Yes
Butaclor MC 31 35 - 43 Medium Yes No
Butaclor MH 30 104 - 124 Medium Yes No
Butaclor MH 31 84 - 104 Medium Yes No
Butaclor DE 102 43 - 57 Very slow Yes No

These Butaclor grades contain a gel phase which confers to the raw compounds better processability in calendering and extrusion.

They can be used either alone or in blend with other mercaptan grades.
Butaclor DE 302 43 - 57 Medium Yes No
Butaclor DE 305 79 - 100 Medium Yes Yes
Butaclor ME 20 48 - 57 Medium Yes No
Xanthogen modified          
Butaclor MC 322 35 - 51 Medium Yes No

Buaclor MC 122, MC322 and MC 323, xanthogen modified grades allow to formulate compounds improved mechanical properties
Butaclor MC 323 35 - 51 Medium Yes No

Butaclor MA 437 95 to 125 1700 to 2200 Fast Yes No
Butaclor MA 41 H 33 to 42 360 to 500 Fast Yes Yes

Butaclor MA 41 H is stabilised with tetraethylthiuram disulfide which accelerates mill peptization and confers more consistent solution viscosity.

Butaclor MC 30 18 to 21 110 to 150 Medium Yes No

Butaclor Mc 30 can be used in addition to the high crystallization rate grades to adjust open time and adhesive film flexibility
Butaclor MA 334 35 to 50 400 to 700 Medium Yes No These Butaclor grades can be used to adjust open time and adhesive film flexibility.
Butaclor MA 335 50 to 80 700 to 1300 Medium Yes Yes
Butaclor MA 336 80 to 95 1300 to 1700 Medium Yes No
