GUARDIAN GP is a single component Acetic cure silicone sealant which vulcanizes on exposure to moisture in the air at room temperature, to produce a flexible elastomeric sealant. It is suitable for all common construction and glazing applications. It is easy to apply and offers excellent adhesion to a variety of nonporous substrates such as glass, glazed ceramic tiles and aluminium. It is resistant to ozone, ultraviolet radiation and temperature extremes.

Properties:

• Mould Resistant, Permanently Flexible, Low Shrinkage
• Kitchen and bath installations (countertops, tubs, sinks, shower, and bath panel joints)
• All-purpose for general contractors
• Carpentry, cabinet assembly and installation
• General sealant and adhesive
• All temperature gun ability – can be applied in alltemperatures
• Excellent resistance to weathering, moisture, ozone, UV, temperature Extremes etc

METHOD OF APPLICATION-SURFACE PREPARATION

All surfaces should be clean and dry and free of dust, dirt, and grease

Priming is normally not required for applications to non-porous surfaces. Applying a small trial bead and allowing 7 days for maximum adhesion to occur can easily test unprimed adhesion. If primer is required contact the manufacturer

APPLICATION

GUARDIAN GP is ready-to-use requires no mixing or additives. The cure mechanism begins as soon as the sealant comes in contact with air. At 25°C (77°F) and 50% relative humidity (RH), the sealant will “skin” within 10 minutes and fully cure in 24 hours (1/8” bead), reaching its maximum adhesion in 7 days. Higher humidity accelerates cure, and curing time is increased with the thickness of the sealant. In applications where partial or total confinement of sealant is prevalent, the time required for proper cure is generally lengthened by the degree of confinement. Tooling, if necessary, should be done before “skinning”

APPLICATION STANDARDS

ASTM C 920-11 Type S, C 719, C 510, C 679, Grade NS

Coverage-One 300 ml cartridge will seal about 10 linear meters of 5mm x 5mm joint.

HEALTH & SAFETY

GUARDIAN GP releases small amounts of acetic acid during cure. Adequate ventilation should be provided with the extensive use of this sealant.

On direct contact, uncured sealant may irritate eyes. Flush well with water and call a physician. Avoid prolonged contact with skin. See Safety Data Sheet (SDS) available on this product.

This product is intended for use only by professional applicators in accordance with the advice given in this document, the SDS and the container(s), and should not be used without reference to the SDS that PME has provided to its customers. KEEP OUT OF REACH OF CHILDREN
