How to use:
1. Keep the surface clean,dry before apply the two polyurethane sealant.
2. In order keep the surface of substrate clean, please use 50mm wide protective tape on both side of the gap(the proper distance from the tape to the gap is 10mm)
3. The mix proportion of component A and component B is 100: 8~12. Mix component A with component B throughly until the color is uniform and no color difference.
4. The prepared product should be used up within 3 hours
5. Remove the protective tape after completion of works. Avoiding water or rain within 24 hours. Irrigation experiment can perform after 7 days. After 28 days, the product properties can be achieved.
T260 Two-Component Polysulfide Sealant is manufactured in accordance with ISO 9001 / 14001 quality assurance system and the Responsible Care Program.
