Wheatherproof building use sealant

Weatherproof building use sealant is a high quality, low modulus, anti-fungal, neutral curing sealant.

The silicone sealant is compatible with all kinds of structural silicone sealant and most adhesives, it has excellent adhesion to alumimum, PVC, stone, ceramic, concrete, metal, plastic, vinyl, wood and most building material, with outstanding weatherproof ability make it good at using outdoor condition

Use: The sealant especially designed for outdoor use, building aluminium panel, curtain wall and outdoor decoration, offers resistance to sunlight, rainwater, snow, ozone and extreme temperatures. It easily extrudes in a wide rang weather condition and quick cures, the cured sealant can maintain its elasticity in temperatures of -50ºC to 150ºC without hardening, cracking or degrading, weatherproof sealant alos can be used for the sealing of vertical and wide joints without slumping.

How to use:
1. The subtract surfaces must be cleaned, dry and free of grease and all loose materials.
2. Inject the sealant by hand-operated or pneumatic caulking gun and fill sealant in the joints. For getting better appearance, cover outside of the joint areas with masking tapes before application. Remove the masking tapes immediately after finishing.

Notes:
1.Uncured sealant avoids contact skin for long time.
2.Incase contact eyes, rinse eyes with large quantities of water and seek medical service.
3.Keep out of reach of children

Restricted application:

The building materials that may exude grease, plasticizer or solvent, etc.Surfaces are made of vulcanized or semi-vulcanized rubber.The place is absolutely sealed and air-insulated . (curing process needs air)The joints which undertake high structural strength, have suffered excessive friction or physical destroy before injecting the sealant .Frosted or humid surface.
