Primer

Inroduction:

It is a solution of various reactive siloxanes and silicone resins in a mixture of isoalkanes. It is a formulated silicone based primer for use with a wide range of silicone sealants. It imparts good adhesion to most metals. It is recommended as a primer for use on non porous surfaces.

Physical Properties & Chemical Properties:

Appearance	:	liquid
Colour	:	yellowish
Density	:	0.76 g/cm3
Viscosity	:	1mm2/s
Flash point	:	3OC
Ignition temperature	:	370oC

How to use:

1	Surfaces to be bonded should be dry and free from grease, oil ,dust and release agents.
2	Non porous substrates ,including that of silicone rubber,could be solvent degreased prior to application.
3	Primer should be applied with a unit –free cloth or paint brush and allowed to dry thoroughly at room temperature for 15 to 45 minutes before applying the sealant.
4	Drying should be carried out in a ventilated area.

Applications:

1	Used with addition curing silicone rubber from RTV-2 & LSR to achieve adhesion to metallic and non metallic substrates.
2	It may be used to bond these silicone products to metals.

Advantages:

1	Suitable for use with ACC and RTV sealants .
2	Suitable for non porous surface.
3	For use with silicoset 1& Part RTV’s.
4	Provides good resistance to water immersion.

Packing:

Available in 100 ml, 1 Lt & 20 kg containers.

Handling & Safety:

1	Avoid direct sunlight and heat sources. After it has been tightly sealed, store the product in a dark and cold indoor area at 10°C or below.
2	Use the product in a well-ventilated area by operating local ventilating equipment in order to prevent any inhaling or absorbing through the skin.
3	Wear eye protection, protective gloves and respiratory protection when handling the product.
4	For an electrostatic prevention, have equipment and devices grounded.
5	Since it is flammable, strictly prohibit the use of fire equipment.
6	Since foreign substance causes decomposition, ensure that dust or other foreign substances are not entered during the mixture.
