Product Features

1.  KLX-717 Silicone weatherproof Sealant for Stones & Marbles can produce superior adhesion to most building materials without base primer.
2.  Easy to use: it can keep good consistency and easy to extrude at - 25℃ ~ 50 ℃.
3.  Excellent thixotropy and extrusion properties, it can be extruded at any normal temperature (- 40 ~100 ℃).
4.  Good adhesion, excellent adhesion to stone, ceramics and cement components and other building materials; no pollution to porous materials.
5.  Excellent weather and aging resistance, excellent tensile and compressive resilience, can bear ±20% displacement capacity.
6.  Neutral solidification, no corrosiveness to stone, cement and other building materials, overcome the shortcomings of acid glue (ordinary glass glue) corrosive materials.

Main Applications

1.  KLX-717 Silicone weatherproof Sealant for Stones & Marbles is suitable for sealing of dry-hanging marble or granite curtain wall engineering project and cement prefabrication engineering project;
2.  Concrete expansion joint sealing of road engineering project;
3.  Bonding and the joint sealing of sanitary ware installation, ceramic engineering project;

Usage Restrictions

KLX-717 Silicone weatherproof Sealant for Stones & Marbles is not suitable for structural assembly use and the following conditions:

1.  All materials that ooze grease, plasticizer or solvent, some unvulcanized or partially vulcanized rubber and adhesive tapes;
2.  The construction part that is not ventilated since silicone sealant needs moisture in the air to solidify;
3.  Long-term immersed and year-round underground damp environment;
4.  Paint surface, because the cracking or peeling of the paint film may cause the failure of sealing;
5.  Frosted or damp surface;
6.  Surfaces with direct contact with food;
7.  Areas susceptible to mechanical wear;
8.  Not advisable to construct when the surface temperature of the material is lower than 4℃ or exceeds 40℃.

Construstion Guide

1.  Clean the interface before using, if necessary, use special solvents to clean and keep dry. If primer is used to enhance the adhesion, it must be constructed after the primer is dried.
2.  Completely filling to the joint to ensure bonding on both sides during construction.
3.  Adhesive tapes should be affixed to the place where protection is needed, but the tape should not touch the surface to be constructed.
4.  Trim immediately before curing to achieve a beautiful appearance.

Safety Attentions

1.  Maintain a good ventilation environment at sealant construction site; and
2.  keep out of reach of children to avoid eating by mistake;
3.  If the eyes are inadvertently exposed to the uncured adhesive, promptly wash with plenty of clean water and ask help from a doctor.

Storage & Validity

1.  KLX-717 Silicone weatherproof Sealant for Stones & Marbles should be stored in the original packaging under dry and ventilated conditions with temperature at 27 ° C or lower.
2.  The product shelf life is 12 months from the date of production.
