Sealant

Product Information

Description
Termicide Sealant is a one component, non-flowing, NEUTRAL cure, and MID modulus silicone sealant. It cures by absorption of atmospheric moisture to form a flexible and durable elastomeric sealant.

Special Features
Termicide Sealant is a sealant for use in saw cuts, shrink cracks, ant capping and general construction. It offers good adhesion to galvanising, zincalume, PYC and concrete. The thixotropic nature of this product ensures that it will not
slump in typical construction joints.

Typical Uses
It provides a termite resistance seal when used in conjunction with other termite resistant products,
Tilt up panels: fills the voids between panels PYC strip
Shielding: fills the joints in the shielding
Saw cuts: is used to fill the saw cut
Shrinkage cracks: it is used to fill the crack
Exposed key joints: it fills the joints between concrete
Ant capping: it fills the gap between hold down rods, bolts and joins.
Exposed slab edge construction
Construction joints

One Part System
Being one-part Termicide Sealant offers the confidence of consistent even cure. It also improves operator productivity, as time is not lost mixing the product, is easy to use in difficult locations, and can be applied out of a standard caulking
gun.

Packaging
The standard packaging for Termicide Sealant is 41O-grampolyethylene cartridges.

Long Life Reliability
Termicide Sealant has excellent natural aging stability. It will maintain its elastomeric joint sealant properties permanently, even under harsh conditions and temperature extremes.

Sealant Application

Joint Design
The Termicide sealant must be capable of withstanding the expectedjoint movement. To calculate the joint width, establish the expected movement (expansion, contraction and shear movement) that the joint is required to withstand. The dynamic movement capability of Termicide Sealant is:1:20. The Data Sheet on Joint Design contains the formula for calculating the required joint width from the expected joint movement and the dynamic movement capability of the sealant. Thejoint design must avoid three -sided adhesion. The sealant depth for a weather seal is normally half the joint width. The minimum acceptable joint depth is 6mm; therefore, if the required joint width is 6mm the depth is also 6mm.

Back up Material
Use a closed cell polyethylene-backing rod, 25% larger than the joint width, to control the depth of the joint.

Compatibility with Adjacent Substrates
Silicones are not always compatible with plasticised sealants, such as butyls. Also some backing rods and glazing tapes contain bitumen or other agents that are incompatible with the silicone. The incompatibility may cause discolouration, poor sealant cure or long-term degradation of the sealant. Always carry out compatibility tests where contact with potentially incompatible materials occurs.

Application
Always ensure that the surfaces to be sealed are dry and free from oil, dirt and grease. Use the two -wipe process for impervious substrates. Ensure the cloths are clean and changed frequently, and use a suitable solvent such as White Spirits. Typical substrates are aluminium, PVC and zincalume. For porous surfaces such as concrete, abrade the surface to remove loose particles. When extruding the sealant cut the nozzle to the desired width, cut the tip off the cartridge, and apply the sealant firmly to ensure good contact between the sealant and the substrate. Before the sealant has skinned, tool it off to ensure a good finish, and to improve the wetting out of the sealant to the substrate. To achieve satisfactory adhesion a primer may be required for some substrates (PVC). Consult the manufacturer or your distributor for more information.

Curing
Termicide Sealant cures by absorbing atmospheric moisture, it will skin over in 9 minutes and cure to a depth of 7mm in 7 days.

Design Support
Because of the importance of Surface Preparation, Sealant Application and Joint Design Termicide Pty. Ltd. provide specific Data Sheets on these topics. These Data Sheets are available Free of Charge, and we strongly recommend that you consult these sheets before commencing application of the sealant. We will also review shop or working details, test substrates, and associated materials for compatibility and adhesion, and make sealant recommendations when requested.

Storage and Shelf Life
Always store the sealant in a cool dry place. Ideal storage temperature is not more than 25°c. Prolonged storage at high temperatures may affect shelf life and ultimate performance. The shelf life of Termicide Sealant is 9 months trom the date of manufacture when stored below 25°C and below 50% relative humidity.

Limitations
Termicide Sealant is NOT suitable_foruse in the following applications:
. As the sealant requires atmospheric humidity to cure, it will not cure in totally confined spaces where it does not have access to atmospheric humidity.
. Structural Glazing.
. Under Water Applications (including swimming pools)
. N. B. Thisproductis suitable for some applications where the sealant is in contact with water for extended periods. Please contact Termicide Pty Ltd. to confirm your design details before commencing such an application.
. Below Grade Applications.
. Stone (We recommend the completion of a stain testing program before using any sealant on stone)
. This silicone is not paintable

Health and Safety.
Termicide Sealant is not classified as a Dangerous Good but is classified as a Hazardous Substance according to the ADG Code and Work safe Australia respectively. The product however, should be used in accordance with good occupational, health and safety practices. May cause irritation if swallowed, moderately irritating to eyes. Repeated or prolonged skin contact may lead to irritation. High concentrations of vapour may irritate respiratory tract. Releases methyl ethyl ketoxime (mcko) until fully cured. Do not swallow and avoid contact with the skin as this may cause sensitisation. If contact with the eyes occurs, wash eyes with copious quantities of water and consult a doctor if irritation persists The Material Safety Data Sheet defining the known hazards and describing the appropriate safety precautions with respect to the product is available through Termicide Pty. Ltd.
