GE SCS1200

Anyone know where I can pick up a tube of this stuff locally in Edmonton?

Aqua Giant sells it for $10 a tube. I believe they have both clear and black.

edmonton fasterns should have them i think they are around 6.8 not 100% sure on this as we buy them in case lots

you will want to ask for the scs1201 which is clear or the scs1203 which is black


another good silicone to look into would be momentive rtv 103(black) or the rtv 108(clear). we are testing these out right now, as the scs1200 series seems to have made a change in the last few months. the momentive silicone a lot more expensive but have heard good things about them.

Awesome!! Thanks a lot for the help

Came across this, more than I wanted to know but very informative

RTV102, RTV103, RTV106, RTV108, RTV109, RTV112, RTV116 and RTV118 one-component, ready-to-use adhesive sealants are extremely versatile. They cure to a tough, durable, resilient silicone rubber on exposure to atmospheric moisture at room temperature. Acetic acid vapors are released from the sealant surface as a by-product of cure.

RTV102, RTV103, RTV108 and RTV109 sealants are standard strength paste consistency products which can be applied to vertical and overhead surfaces where pourable/self-leveling sealants are not practical.

RTV112 and RTV118 sealants are self-leveling products which are preferable to paste-consistency sealants when flow into small crevices and hard-to-reach places is desired.

RTV106 sealant is paste-consistency sealant. RTV116 sealant is a self-leveling sealant. Both RTV106 and RTV116 sealants are standard strength high-temperature sealants.


In other words:
RTV102 White
RTV103 Black
RTV108 Translucent
RTV109 Aluminum
are genreal purpose


RTV106 Red
is a high temperature paste

RTV116 Red
is high Temperature

RTV112 White
RTV118 Translucent
are general purpose.

RTV102, RTV103, RTV108, RTV109, all have identical physical properties. The others are less "strong" in tensile, elongation, and tear strength.

Is it safe? First you must sign the papers..........


FDA STATUS
RTV102, RTV103, RTV106, RTV108, RTV109, RTV112, RTV116 and RTV118 sealants can be used in food contact applications where FDA regulations apply. Reference CDS4319 ?Food Contact Applications, Silicone Rubber Compounds?, for specific regulations, limitations and conditions of use.


USDA STATUS
RTV102, RTV103, RTV106, RTV108, RTV109, RTV112, RTV116 and RTV118 sealants may be used on equipment which may contact edible products in official establishments operating under the Federal meat and poultry products inspection program. See USDA letter of Authorization. Refer to Momentive Performance Materials bulletin CDS #4319 before use.

This information, is not contained in the MSDS sheets for these products, you can tell little if anything by reading the MSDS, as most will not even know what the chemical formulations mean (some have food color in them)

What does it mean? It is strong and safe. Really the only two that have any use in an aqaurium are RTV103, and RTV108 (Black and translucent respectively) They have identical properties, the same material, just different color.

A tour of the AGA/Aqueon facility, revealed that these are the products used to build tanks. It is not the same product that is packaged for consumer use, under the AGA/Aqueon lable, as the MSDS sheets indicate. A conversation first with GE, quite some time ago, and another conversation with Momentive, revealed that the RTV100 series silicones are the most used silicones by tank builders.

Silicone is not intended for, or recommended for, attempting to bond acrylic to glass. The properties that glass and silicone hold in common (inorganic silica) are responsible for the strong bond. Acrylic, being an organic based material (oil derivative) does not have these properties.
