Purpose

It is a single-component silicone weather-proofing sealant, and is mainly used for bonding and sealing of plastics-steel door and window, aluminum alloy, stainless steel door and window, as well as PVC and ABS building joints.

Characteristics

1. Have special bonding property between PVC plastic and wall;

2. Excellent bonding property and wide application;

3. Neutral curing, slight odor, and no corrosion to base material;

4. Weather proofing, best ultraviolet resistance and high and low-temperature resistance;

Construction instructions and notices

1. The product is not suitable for application of structural seal or engineering application that surface temperature of base material is over 50℃;

2. The surface applying sealant must be clean without dirt;

3. When applying, sealant must filled and compacted the gaps between base materials, making it fully contact with base materials, avoiding air bubbles or cavities due to fast applying;

4. Secondary applying of sealant is required when the cavity width is over 2cm or it is applied on foaming body;

5. Please keep the construction site ventilated;

6. Do not contact sealant for a long time during use, and please see a doctor immediately once splashing into eyes.

Storage

It is stored in dry environment below 27℃ in a period of 9 months, and 6 months for color mixing sealant, unavailable for use if shelf life expired.
