BP 6007 is a fast-setting, three component polysulfide that will cure at room temperature into a very flexible rubber mold with excellent dimensional accuracy and stability. When a mold is to be used to cast epoxy, polyester, or to make a negative rubber mold, a release film will be required. A diluted PVA solution is recommended.

Features:
Mix ratio (by wt.): See datahsset
Viscosity (mixed): 6,500cps
*Cure time (hrs)(72°F): Dependent on mix ratio
Hardness (shore): 10A
Color: Black
Datasheet
*note: less than 15 parts hardener will not cure product

BP 6008 Cold Setting Rubber (CSR) is a slow-set, two component polysulfide molding system specially formulated for casting that will cure at room temperature into a very flexible rubber mold with excellent dimensional accuracy and stability.
BP 6008 will bond to itself so that changes or additions to a CSR mold may be made at any time. When a CSR mold is to be used to cast epoxy, polyester, or to make a CSR negative mold, a release film will be required. A diluted PVA solution is recommended. CSR will soften laquered surfaces if left in contact with these surfaces for more than two hours.

Features:
Mix ratio(by wt.): See datasheet
Viscosity (mixed): 6,500cps
*Cure time (hrs)(72°F): Dependent on mix ratio
Hardness (shore): 10A
Color: Black

*note: less than 12 parts hardener will not cure product

BP 6604 Cold Setting Rubber (CSR) is a two component polysulfide molding system specially formulated for casting that will cure at room temperature into a very flexible rubber mold with excellent dimensional accuracy and stability. Before pouring the freshly mixed CSR into a mold, allow 3-4 minutes for the air to rise to the surface. A full cure will take place overnight (16 hours).

Features:
*Mix ratio(by wt.): See datasheet
Viscosity (mixed): 6,500cps
Cure time (hrs)(72°F): 16
Hardness (shore): 4A
Color: Black

BP 6608 Cold Setting Rubber (CSR) is a, two component polysulfide molding system specially formulated for casting that will cure at room temperature into a very flexible rubber mold with excellent dimensional accuracy and stability.
Thorough mixing is necessary to insure a uniform mix as the hardener will settle rapidly to the bottom of the mixing container when added to the CSR resin. Before pouring the freshly mixed CSR into a mold, allow 3-4 minutes for the air to rise to the surface. A full cure will take place overnight (16 hours).

Features:
*Mix ratio(by wt.): See datasheet
Viscosity (mixed): 6,000cps
Cure time (hrs)(72°F): 16
Hardness (shore): 15A

BP 6920 is a two component polysulfide molding system utilizing a low toxicity manganese dioxide hardener, formulated especially for casting tire foundry molds. It has a low viscosity with excellent flow characteristics enabling it to duplicate fine mold detail, while allowing entrapped air to escape. After curing, BP 6920 may be easily stretched to release from delicate porous plasters and still maintain excellent Total Indicated Run-out (TIR).

Features:
Mix ratio(by wt.): See datasheet
Viscosity (mixed): 6,500cps
Cure time (hrs): 3 (complete 16 hrs) *Hardness (shore): Dependant on mix ratio
