OLV77 Caulk Sealant

1, one part,water based,paintable caulking pound
2, medium to high grade, good adhesion
3, sealing and filling gaps and joints
Description:
OLV 77 Caulk Sealant for windows and doors is a one part, water based acrylic sealant that cures to a flexible and tough rubber with good adhesion to porous surface without primer. Suitable for sealing and filling gaps or joints where low demands of elongation are required.

Main purposes:
1. Mainly for sealing the gaps or joints interior and exterior, such as doors and window frames, walls, window sills, prefab elements, stairs, skirting, corrugated roof sheets, chimneys, conduit-pipes and roof gutters;
2. Can be used on most construction materials, such as brick, concrete, plasterwork, asbestos cement, wood, glass, ceramic tiles, metals, aluminum, zinc and so on;
3. Acrylic sealant for windows and doors.

Characteristics:
1. One part, water based acrylic sealant that cures to a flexible and tough rubber with good adhesion to porous surface without primer;
2. Suitable for sealing and filling gaps or joints where low demands of elongation are required.

Limitations:
1. Unsuitable for permanently flexible sealing, for cars or spaces where wet conditions exist, e.g. aquaria, foundations and swimming pools;
2. Do not apply at temperature below 0;
3. Be not fit for continuous immersion in water;
4. Keep out of reach of children.

Tips:
1. The joint surfaces must be clean and free from dust, rust and grease. Tar and bitumen substrates reduce the bonding ability;
2. In order to improve the bonding ability to strongly absorbing porous surfaces, such as stone, concrete, asbestos cement and plasterwork, these surfaces should first be primed with a diluted sealant (1 volume of Acrylic Sealant to 3-5 volumes of water) until the primer to dry completely.

Shelf life: Acrylic Sealant is sensitive to frost and must be kept in tightly closed packing in a frost-proof place. The shelf life is about 12 months when stored in a cool and dry place.
